Undermining long-held paradigms

Nemesis-Juggernaut: This assertion, that most biologists believe mammals did not exist along with dinosaurs, is false and has been false since at least the late 60s when I first started following paleontology.A very basic google search would show this:Mammal - WikipediaAdditionally, mammals obviously had to exist contemporaneous with dinosaurs in order to supersede them after the K-T extinction event, unless of course, they were poofed into existance.

NJ misrepresenting biologists concerning contemporaneous existance of mammals and dinosaurs states: Name them. I would bet every single one is due to the fact you, and your apparent sources at AIG and ICR either misinterpret or misrepresent science. The tissue in question is not unfossilized facial tissue. It is from a leg bone. More disinformation from NJ.T. rex Fossil Yields Soft Tissue | NSF - National Science FoundationDo you hate telling the truth? How do you think your God may respond to such falsehoods should there be a judgement day?

Nemesis_Juggernaut: "Far from anything factual" in anti-science fantasyland, there is a lot of evidence. An asteroid Chicxulub, strikes the Earth, as shown by geology. Strangely enough there is all these shocked quartz grains showing up all around the event. Stranger still, there is all this iridium, rare on Earth but more common on certain asteroids, showing up in this very narrow layer of sediments. Dinosaur fossils show up below the layer but not above. What kind of conclusion is one supposed to make?Sure a few blame the volcanism of the Deccan traps, but as stated here before, the events are in all likelihood directly related. I think the asteroid caused the volcanism.The evidence is compelling. Many of your assertions, given your history here, are not.ABE - I guess we are making progress if you accept that dinosaurs are extinct and asteroids strike the planet.Edited by anglagard, : misplaced quotes and NJ progressEdited by anglagard, : clarity

Technically that is correct under the modified Benton Classification system. The Class Aves (birds) is under the Order Saurischia. I think you are being conservative in this. The object would be an asteroid or comet I would think. The iridium argument is based upon the chemical makeup of certian types of asteroids. I am unfamiliar with iridium being considered a trace constituent of comets. Do you have evidence to the contrary?

Nemesis_Juggernaut: Read in its entirety, it sure looks to me that NJ {in the role of speaking for virtually all evolutionary biologists} is denying the coexistance of (non-avian) dinosaurs and mammals as in the phrase "should have ever been contemporaneous with dinosaurs."It is possible that this is not what NJ meant, in which case I'm sure he can correct me and strive to be more concise in his use of the English language in the future.ABE - Also examine the subsequent sentence: Notice the dinosaurs first go extinct, then the proliferation of small mammals is allowed.Once again, NJ is saying, to me at least, that the vast majority of evolutionary biologists did not believe (non-avian) dinosaurs coexisted with mammals to any significant degree or over any significant timespan, if at all.Perhaps in this case proliferation implies preexistance, if one gives the benefit of the doubt.Once again, perhaps NJ can let us know what he really meant.Edited by anglagard, : clarity (for example)Edited by anglagard, : No reason given.

Well, you got me there, I thought it was a mispelling. My post #9 is therefore rendered irrelavant.I apologise for being mistaken.ABE - Note to self: Don't post when you have the fluEdited by anglagard, : No reason given.

Nemesis_Juggernaut reveals: Well, I guess I need to take your posts a lot less seriously. Hope you don't mind that I will still challenge what you assert if I believe it is wrong. However, given this admission, I think I will do so with less venom.

This source claims up to a meter in length for at least some cretaceous mammals. Will check further.http://www.fossilmuseum.net/...Paleobiology/Castorocauda.htm

OK, from Science News 3/18/06:

quote:

IN THE SWIM The latest entry in the early mammalian diversity parade is Castorocauda lutrasimilis-which, translated from Latin, means "beaver-tailed creature that looks like an otter." The 50-centimeter-long creature, about the size of a modern-day platypus, lived about 164 million years ago in what is now northeastern China.

And for weight:

Castorocauda probably tipped the scale at around 800 grams, at least 10 times the weight of its known mammalian contemporaries.

Hope this helps.
