Was the Burkle impact close enough to this iridium layer? It hit in the Indian Ocean.

Speaking of cosmic stuff, is there anyone here that did not know that Voyager 1 is still operational and is currently in interstellar space and approaching the heliopause which is outside out our star system?

And with greeings from President Carter and U.N. Secretary General Waldheim.

the author's counterparts claim that mammoths were still around until just a few thousand years ago. The author's claim mammoths were overhunted to extinction may also be exaggerated, in light of the numerous animals that co-existed with mammoths, i.e., horses, camels, lions, tigers and bears.

Fossils of mammoths, bison, cave bears and horses all seem to disappear from parts of Alaska and Siberia around

35,000 years ago.

“And then they show up again around 10,000 years later,” he said. “So they came in from elsewhere.”

Gillette believes that present-day vegetation in the area is similar to what was here 11,500 years ago. Mammoth remains are most often found in areas that were covered by grasslands during the last Ice Age; in this area, there were likely both conifers and grasses, probably fed by a good water source. The mammoths co-existed with other now-extinct species, such as saber tooth tigers, giant ground sloths, musk oxen, camels, horses, tapirs, and lions.

Great. Just great. Voyager I runs into some alien race out there and those two idiots are going to screw up First Contact, just like they screwed up everything else in their careers.

We'll be lucky if First Contact doesn't degenerate immediately into an interstellar war of extermination. With us as the exterminatees.
