    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...

    Another Cambrian Discovery Discredits Evolution by Jeffrey Tomkins, Ph.D. * A fossil creature from the phylum Entoprocta (invertebrate animals that have tentacles and lacking a mineralized skeleton) was found in marked abundance (over 400 individuals) in Burgess Shale. The Burgess is a sedimentary layer that's purportedly part of the Cambrian period about a half-billion years ago, according to evolutionists.1 The problem for paleontologists is that the supposedly 520 million year old creature looks exactly like its living counterparts, only up to 8 eight times larger. The Cambrian geologic system is an enigma for the evolutionary paradigm. If evolution is true,...
  • Eel-like creature identified as 'earliest human ancestor'

    A prehistoric eel-like creature discovered in a Canadian shale bed has been identified as the earliest known ancestor of man. Fossils dating back 505 million years preserve the relics of tiny, slithering animals which are the oldest life forms ever discovered with primitive spinal cords. As the precursor of vertebrates the species is also believed to be the direct ancestor of all members of the chordate family, which includes fish, birds, reptiles, amphibians and mammals. The finding means the 5cm long creatures, known as Pikaia gracilens, were the forerunners of animals as diverse as snakes, swans and humans, scientists said....

    Our research at the State Key Laboratory of Palaeobiology and Stratigraphy, Nanjing Institute of Geology and Palaeontology, has shown, based on a refined division and correlation of the graptolite-bearing strata in southern Jiangxi, China, that the Kwangsian Orogeny commenced in the early Katian Age of the Late Ordovician. Because of its significant research value, this study is published in Issue 11 of Science China Earth Sciences. An angular unconformity separating the Lower-Middle Devonian and underlying strata is widespread in the Zhujiang region of South China, and occurs across most of Jiangxi, Hunan, Guangxi and Guangdong provinces. This angular unconformity indicates...
  • Fossil of giant ancient sea predator discovered (w/ video)

    The creatures, known as anomalocaridids, were already thought to be the largest animals of the Cambrian period, known for the "Cambrian Explosion" that saw the sudden appearance of all the major animal groups and the establishment of complex ecosystems about 540 to 500 million years ago. Fossils from this period suggested these marine predators grew to be about two feet long. Until now, scientists also thought these strange invertebrates -- which had long spiny head limbs presumably used to snag worms and other prey, and a circlet of plates around the mouth -- died out at the end of the...

    Storming the Beaches of Norman Norman, Oklahoma, that is. Okay, so there aren’t any real beaches in Norman, Oklahoma. But when Steve Meyer and I went there recently, the Darwinists who have installed themselves as absolute dictators at the University of Oklahoma (OU) made our arrival feel like D-Day. On September 28, Steve gave a talk on his best-selling book Signature in the Cell at the Oklahoma Memorial Union on the OU campus. The following evening, September 29, Steve and I answered questions after a showing of the new film Darwin’s Dilemma at the Sam Noble Museum of Natural History,...
  • Fossil embryos deep in the fossil record (40 mya before Cambrian Explosion, yet still look "modern")

    ...The fossilized embryos shatter some ideas about evolution. Not only have certain cellular processes been pushed way back in time, but also there does not appear to be any evolution seen in these embryos, since many cellular processes, including some modern features, go clear back to the beginning of the fossil record. These embryos demonstrate that complex metazoans have been around since at least the Neoproterozoic and that from an evolutionary point of view their origins go back even further. Thus, the origin of animals is firmly based on nothing, and a huge evolutionary mystery: ‘The origin of animals is...

    Mollusk fossils push back evolution, ROM scientists say Life 560 million years ago more advanced than previously believed, article says. Two Canadian paleontologists have discovered dozens of fossils of a soft-bodied, deep-sea dweller that lived more than half a billion years ago, adding one more piece to the enigmatic puzzle that is the history of life on Earth. The 189 well-preserved fossil specimens of Odontogriphus omalus have been interpreted as the world's oldest known soft-bodied mollusk, and were found in British Columbia's mountains in the Burgess Shale, one of the most important fossil sites in the world. The newly discovered...

    Ediacaran assemblages immediately predate the Cambrian explosion of metazoans and should have played a crucial role in this radiation. Their wider relationships, however, have remained refractory and difficult to integrate with early metazoan phylogeny. Here, we describe a frondlike fossil, Stromatoveris (S. psygmoglena sp. nov.), from the Lower Cambrian Chengjiang Lagerstätte (Yunnan, China) that is strikingly similar to Ediacaran vendobionts. The exquisite preservation reveals closely spaced branches, probably ciliated, that appear to represent precursors of the diagnostic comb rows of ctenophores. Therefore, this finding has important implications for the early evolution of this phylum and related diploblasts, some of which...

    American Scientist ^ | May-June 2005 | Derek E. G. Briggs (reviewer)
    The recent surge in interest in the origins of multicellular animals (metazoans) is fueled by new evidence from three major sources: molecular sequencing, the study of evolutionary development and the discovery of exceptionally preserved fossils of Precambrian and Cambrian age, particularly from China. Genetic sequences provide a means of analyzing how the major animal groups are related and of estimating their time of origin (using the molecular clock) — a means that is independent of morphological data and the record of evolutionary events the fossils reveal. The study of developmental processes in an evolutionary framework ("evo-devo") provides the link between...

    After the Army, Clark signs up as businessman Doors open for retired general Retired Gen. Wesley Clark’s business resume reads as if it belongs to an upwardly mobile executive who’s had his nose to the grindstone for three decades. In the three years since he left the Army, Clark has signed on as an adviser or director with more than half a dozen companies, written two books, worked as a CNN pundit and launched a campaign to become president of the United States. The common denominator: He was working with a government he knows inside out. The information that...
  • Study suggests macroscopic bilaterian animals did not appear until 555 million years ago

    RIVERSIDE, Calif. -- The traces left behind by ancient animals may hold the key to determining when macroscopic bilaterians -- animals that are symmetric about a central axis, with a body divided into equivalent right and left halves, and with an anterior-posterior polarity (e.g., this includes worms, ants, and ranging up to humans) -- first appeared. A team led by Dr. Mary Droser, professor of geology at the University of California, Riverside, studied "trace" fossils, e.g., burrows, trails and tracks left behind by the earliest bilaterian animals. Results from their study suggest that bilaterian animals did not appear until approximately...
