    The Washington Post's Speaking of Science ^ | September 4, 2014 | Meeri Kim
    Scientists have discovered the fossilized remains of a new long-necked, long-tailed dinosaur that has taken the crown for largest terrestrial animal with a body mass that can be accurately determined. Measurements of bones from its hind leg and foreleg revealed that the animal was 65 tons, and still growing when it died in the Patagonian hills of Argentina about 77 million years ago. “To put this in perspective, an African elephant is about five tons, T. rex is eight tons, Diplodocus is 18 tons, and a Boeing 737 is around 50 tons,” said study author and paleontologist Kenneth Lacovara at...

    Are there out-of-sequence fossils that are problematic for evolution? by Gary Bates and Lita Cosner Published: 17 April 2014 (GMT+10) In his debate with Ken Ham, (the ‘science guy’) Bill Nye dogmatically claimed, and asked Ham, to cite any out of order fossils in the geologic record, because if there were any, it would be problematic for the evolutionary model. Due to the seeming confidence of Nye’s assertion (and that it was not answered during the debate), many have contacted us for an answer on this single question. In addition, while out on ministry our speakers have mentioned how this...

    The oldest human footprints ever found outside Africa, dated at between 850,000 and 950,000 years old, have been discovered on the storm-lashed beach at Happisburgh in Norfolk, one of the fastest eroding stretches of the British coast. Within a fortnight the sea tides that exposed the prints last May destroyed them, leaving only casts and 3D images made through photogrammetry – by stitching together hundreds of photographs – as evidence that a little group from a long-extinct early human species had passed that way. They walked through a startlingly different landscape from today’s, along the estuary of what may have...

    Trilobites are one of the most popular fossils for collectors and are found all over the world. The Ute Indians used one species as an amulet, and there is even a cave in France called the Grotte du Trilobite that contained a relic made out of one of these extinct marine creatures.1,2 Trilobites are members of the phylum Arthropoda, which includes spiders, insects, and crustaceans. Today, members of this group make up at least 85 percent of the species on Earth and live in every environment. Insects alone account for over 870,000 of these species.1 God designed all arthropods with...
  • Primate fossil 'not an ancestor'

    The exceptionally well-preserved fossil primate known as "Ida" is not a missing link as some have claimed, according to an analysis in the journal Nature. The research is the first independent assessment of the claims made in a scientific paper and a television documentary earlier this year. Dr Erik Seiffert says that Ida belonged to a group more closely linked to lemurs than to monkeys, apes or us. His team's conclusions come from an analysis of another fossil primate. The newly described animal - known as Afradapis longicristatus - lived some 37 million years ago in northern Egypt, during the...

    Scientists at the Georgia Institute of Technology have found genetic evidence that seems to support a controversial hypothesis that humans and chimpanzees may be more closely related to each other than chimps are to the other two species of great apes – gorillas and orangutans. They also found that humans evolved at a slower rate than apes. Appearing in the January 23, 2006 issue of the Proceedings of the National Academy of Sciences, biologist Soojin Yi reports that the rate of human and chimp molecular evolution – changes that occur over time at the genetic level – is much slower...

    The brains of chimpanzees show a number of similarities to human brains, the results of two new studies suggest. Findings published in the December issue ofBehavioral Neuroscience indicate that the animals have differences between the right and left sides of their brains in much the same way that humans do. In addition, it appears that the neurological basis for handedness is not unique to our species. Hani D. Freeman of the Yerkes National Primate Research Center and his colleagues scanned the brains of 60 chimpanzees with magnetic resonance imaging (MRI) and measured two key regions of the brain's limbic system,...

    Despite decades of study, geneticists don't know what makes humans human. Language, long arms, and tree-climbing prowess aside, humans and our kissing cousins, chimpanzees, share practically all of our DNA. Genomic studies have suggested that the regulation of genes, rather than the genes themselves, set the two primate species apart. But genes are still an important part of the story, says Michele Cargill, a geneticist at Celera Diagnostics in Alameda, California. She and her colleagues found key differences between chimp and human genome coding sequences, differences that propelled human evolution and sometimes lead to genetic diseases. Genes for olfaction and...

    Why the Y chromosome is a hotbed for evolution Mark Henderson, Science Editor The Y chromosome is often seen as the rotten corner of the human genome — a place of evolutionary decline that is slowly decaying and threatening the end of man. Reports of its imminent demise, however, have been exaggerated. Research has indicated that, far from stagnating, the male chromosome is a hotspot of evolution that is changing more quickly than any other part of humanity’s genetic code. In most mammals the sex of offspring is determined by X and Y chromosomes. Females have two Xs, males have...

    A group of researchers from Korea and Japan has deciphered the Y chromosome of chimpanzees' genetic code, getting a step closer to solving the mysteries surrounding human evolution. It is well known that we share more than 98 percent of our DNA and almost all of our genes with the chimpanzee. Now the researchers have decoded more than half of the Y chromosomes, or 12.7 million base pairs, of man's closest living relative. "Because no genetic exchange occurs, the Y chromosome is important in explaining the evolution process," said Park Hong-seog, a senior researcher at the Korea Research Institute of...

    Since the human-chimp split about 6 million years ago, chimpanzee genes can be said to have evolved more than human genes, a new study suggests. The results, detailed online this week in the Proceedings of the National Academy of Sciences, contradict the conventional wisdom that humans are the result of a high degree of genetic selection, evidenced by our relatively large brains, cognitive abilities and bi-pedalism. Jianzhi Zhang of the University of Michigan and his colleagues analyzed strings of DNA from nearly 14,000 protein-coding genes shared by chimps and humans. They looked for differences gene by gene and whether they...

    Each poo is a time capsule to the dawn of the dinosaurs. A gigantic "communal latrine" created at the dawn of the dinosaurs has been unearthed in Argentina. Thousands of fossilised poos left by rhino-like megaherbivores were found clustered together, scientists say. The 240-million-year-old site is the "world's oldest public toilet" and the first evidence that ancient reptiles shared collective dumping grounds. The dung contains clues to prehistoric diet, disease and vegetation says a study in Scientific Reports. Continue reading the main story [snip]

    Two fossils have got palaeontologists scratching their heads about where to place an enigmatic group of animals in the mammalian family tree. A team analysing one fossil suggests that the group belongs in mammals, but researchers looking at the other propose that its evolutionary clan actually predates true mammals. The situation begs for more analysis, more fossils, or both, experts say. The fossils represent previously unknown species, described today in Nature1, 2. Both are members of the haramiyids, a group of animals that first appeared around 212 million years ago and that researchers first recognized in the late 1840s. Until...

According to The Sydney Morning Herald, "Migaloo quickly located the 600-year-old remains of an indigenous Australian,"1 which researchers found a decade ago. But that specialized training resulted in an unforeseen crossover—Migaloo can also smell fossils. Fossils are supposed to be rocks in the shape of bones, with no original bone material remaining.

    Scientists have revealed insights into a peculiar, phallus-shaped creature discovered at a fossil site in Canada. The animal has been identified as Spartobranchus tenuis, a species from the Cambrian period that was previously unknown to science. The odd-looking creature was an ancient relative of acorn worms that exist today, according to researchers. Their study, published in the journal Nature, is the first full description of the prehistoric animal. Remains of soft-bodied worms were found in the Burgess Shale fossil beds in Yoho National Park, British Columbia, Canada throughout the last century. But now researchers studying the 505 million years old...

    Cryptic comments seem to have an ambiguous, obscure or hidden meaning. In biology, cryptic species are outwardly indistinguishable groups whose differences are hidden inside their genes. Two University of Michigan marine biologists have identified three cryptic species of tiny clams, long believed to be members of the same species, which have been hiding in plain view along the rocky shores of southern Australia for millions of years. The unusual convergence of a climate-cooling event and the peculiarities of local geography caused the three cryptic species to split from a common ancestor more than 10 million years ago, the U-M researchers...

    Chinese researchers have tracked the "exceptionally well-preserved fossils" to the Middle Triassic of China (235-242 million years ago). The Triassic period saw the re-establishment of ecosystems after the Permian mass extinction. The fossils represent new evidence that marine ecosystems re-established more quickly than previously thought. The Permian mass extinction had a bigger impact on the earth's ecological systems than any other mass extinction, wiping out 90-95% of marine species. Previous studies have suggested that Triassic marine life developed more quickly than was once thought and that marine ecosystems were re-established more rapidly than terrestrial ecosystems...

    The behaviour of an ancient horseshoe crab in its final moments before death has been captured in the fossil record. A 9.7m-long trackway was created around 150 million years ago when a horseshoe crab fell into a lagoon. The find is of interest because the fossil of the animal itself is present at the end of the trackway, where the animal died. The research appears in the journal Ichnos. The fossil trackway of the animal's last moments - known as a mortichnia, or death march - was discovered in the lithographic limestone of Bavaria in Germany in 2002, where spectacular...

Oliver Rauhut, curator of the Bavarian State Collection for Palaeontology and Geology in Munich, announced the find yesterday. Although Chinese bird and dinosaur fossils are famed for delicate details such as their feathers, they don't match this 72-centimetre-long theropod in terms of clarity and completeness of preservation. The young dinosaur has been dated at 135 million years old, putting it in the early Cretaceous, but it has yet...

    A giant cache of nearly 20,000 fossil reptiles, shellfish and a host of other prehistoric creatures unearthed from a mountain in China is now revealing how life recovered after the most devastating mass extinction on Earth. This research could help point out which species might be more or less susceptible to extinction nowadays, and how the world might recover from the damage caused by humanity, scientists added. Life was nearly completely wiped out approximately 250 million years ago by massive volcanic eruptions and devastating global warming. Only one in 10 species survived this cataclysmic end-Permian event. Much was uncertain regarding...

    For fossil hunters, it represents one of those breakthrough moments. A pterosaur has been found in China beautifully preserved with an egg. The egg indicates this ancient flying reptile was a female, and that realisation has allowed researchers to sex these creatures for the first time. Writing in Science magazine, the palaeontologists make some broad statements about differences in pterosaurs, including the observation that only males sported a head-crest. David Unwin, a palaeobiologist in the Department of Museum Studies at the University of Leicester, was part of the research team. He told the BBC the discovery was astonishing: "If somebody...

    Topeka — About 80 million years ago, the Pteranodon longiceps flying reptile would not have been powerful enough to swoop down and successfully nab the big Xiphactinus audax fish. In a bid to be designated the official state fossil, though, don't count the pteranodon out yet. On Monday, state Reps. Tom Sloan, R-Lawrence, and Don Hineman, R-Dighton, introduced a bill to declare the fossil of the Xiphactinus audax the official fossil of the state of Kansas. The bill's genesis came from Sloan's constituents. On Wednesday, Sloan said, he started hearing views that the more fitting state fossil was the pteranodon....

    I found all of these on my first outting in one creek. I was told the large teeth are from a mastodon but they don't look like the ones I've seen on the web. The vertabra I was told, are maybe from a mosasaur.

    Specialists and collectors around the world have long decried the flood of sham fossils pouring out of China. But Science has learned that many composites and fakes are now finding their way into Chinese museums, especially local museums. One paleontologist estimates that more than 80% of marine reptile specimens now on display in Chinese museums have been "altered or artificially combined to varying degrees." One consequence of the fakery is an erosion of trust in museums, which are supposed to enlighten—not con—the public. Scholars, too, pay a price: They waste time sifting authentic specimens from counterfeit chaff. And a genuine...

    The Utah reptiles belong to the horned-dinosaur family, which is known for outlandish anatomy, and are wowing seasoned fossil hunters. The species named Kosmoceratops had 15 horns decorating its massive head, giving it the most elaborate dinosaur headdress known to science. At 15 feet long, it was larger than a Ford Fiesta. Its name means "ornate horned-face" in Latin. The newly discovered dinosaurs, close relatives of the famous Triceratops, were announced today. Utah scientists believe most of the horns were used to attract mates and intimidate rivals of the same species. The dinosaur fossils were found in the Grand Staircase-Escalante...

    RIVERSIDE, Calif. – A utility company preparing to build a new substation in an arid canyon southeast of Los Angeles has stumbled on a trove of animal fossils dating back 1.4 million years that researchers say will fill in blanks in Southern California's history.The well-preserved cache contains nearly 1,500 bone fragments, including a giant cat that was the ancestor of the saber-toothed tiger, ground sloths the size of a modern-day grizzly bear, two types of camels and more than 1,200 bones from small rodents. Other finds include a new species of deer, horse and possibly llama, researchers affiliated with the...

    Bob Schieffer on Sunday blamed the internet for the growing number of Americans that think Barack Obama is a Muslim. Namelessly referring to last week's Pew Research Center poll finding that eighteen percent now believe this, the "Face the Nation" host concluded Sunday's program saying that "in the internet age, ignorance travels as rapidly as great ideas."

    Fossils of what could be the oldest animal bodies have been discovered in Australia, pushing back the clock on when animal life first appeared on Earth to at least 70 million years earlier than previously thought. The results suggest that primitive sponge-like creatures lived in ocean reefs about 650 million years ago. Digital images of the fossils suggest the animals were about a centimeter in size (the width of your small fingertip) and had irregularly shaped bodies with a network of internal canals. The shelly fossils, found beneath a 635 million-year-old glacial deposit in South Australia, represent the earliest evidence...

    On our way through eastern Tennessee on US 26 for the fortieth time, give or take a few, we decided to visit the Gray Fossil Museum. It is one of the most extraordinary preserves of fossilized bones of long-extinct creatures ever found. An excellent book describes how this sink hole that preserves thousands of whole skeletons of ancient creatures was discovered, preserved and exploited. The book is The Bone Hunters by Harry Moore. In some cases, the scientists can identify a species from a single tooth. Compare paleontology to political science. We know more about the life and death of...

    Remarkably well preserved for a two-million-year-old fossil, this child's skull belongs to Australopithecus sediba, a previously unknown species of ape-like creature that may have been a direct ancestor of modern humans, according to a new study in Science. Scientists think this particular Australopithecus sediba fossil is from a male between 8 and 13 years old. The child's fossils were found in the remnants of a subterranean South African cave system alongside the fossil remains of an adult female in her 30s. "It's the opinion of my colleagues and I that [A. sediba] may very well be the Rosetta stone that...
  • First Chimpanzee Fossils Cause Problems for Evolution

    by Dr. Fazale ("Fuz") Rana Where were you on September 1, 2005? Perhaps you missed the announcement of a scientific breakthrough: the influential journal Nature published the completed sequence of the chimpanzee genome.1This remarkable achievement received abundant publicity because it paved the way for biologists to conduct detailed genetic comparisons between humans and chimpanzees.2Unfortunately, the fanfare surrounding the chimpanzee genome overshadowed a more significant discovery. In the same issue, Nature published a report describing the first-ever chimpanzee fossils. This long-awaited scientific advance barely received notice because of the fascination with the chimpanzee genome. News of the two discoveries produced different...
