Simple google search turn this up: http://www.internacional.edu.ec/publicaciones/arco_iris/001/english/magazine001b.htm A piece of burned bone which had been carbonized would leave a distinct trace fossil as opposed to a mineralized fossil. Besides, nothing ever burns completely in a fire storm, something is always left. Even in a nuclear blast, something is left a ways from ground zero. And birds did survive it, so there had to be breaks in the flashover pattern. And as for marine lifeform, all the forams show you is that something in the water hit them. Dinosaurs had made it past weather changes before and so had forams. You cannot equate a foram to any land dwelling creature. It will not hold up when all the cards are placed on the table. All you have is a marine lifeform and a land lifeform and for all we know, there was a sudden uptake of a crutial mineral in the water which left the forams in a hurt. Ever wonder why there are some species of radiolarlia which uses strontium instead of silica for thier tests? There are no dinosaur bones within many feet of the K-T boundary and none have yet to be found in the boundary. That is the important clue. They had already died out, so something other than the K-T event did it. I could have been another impactor, but no one has found another layer with a high iridium content that is earlier and at a dinosaur fossil level. So, it is most likely something else that caused the end of the dinosaurs. A reptilian pandemic has been suggested, but not proved. Personally, I think it was a major loss of the ozone layer and the beasties without complete body coverings of hair or feathers got serious sunburns which became cancerous or they got radiation sickness and died from that exposure. Either way, it would have eliminated all the megaforms including the marine and flying reptiles. But, the fact is, there have been no correlating dinosaur fossils found at the K-T boundary. This is the significant fact that these people never mention whenever they publish the "Dinosaur Extinction Event". Has Bakker, Horner, Currie, Sareno or dozens of other world class experts come forward and published that the K-T boundary is what caused the end to dinosaurs? No, they only say that below it you can find bones and above it you don't, but they also qualify it with how far below. So, anyone who uses some other lifeform dying off as proof that another lifeform died doesn't have enough sandwiches for a picnic. When you have one lifeform dying off side by side with another, then you have evidence for something which may well lead to the proof. Now, there is one possibility that really needs looking at, find a marine reptile that has died in the youngest rock you can find before the K-T boundary, and look for your forams there and talk to me about what's different or not between these "associated" forams and those forams at the K-T boundary. That would be a meaningful study which might lend real clues to a worldwide reptilian die off. But without the "associated" fossil bones, you have nothing. I want to hear about real scientific investigation here, not smoking guns and some astrophysicist's "expert" opinion (read that as mathmatical models) or some foram expert's "proof" on the end of the dinosaurs. Let the dinosaur experts come forward and say they have proof. This is like saying "Because all the cable channels are carrying reality or religious shows, everyone, absolutely everyone, must be watching them with no exceptions". Now, can we get on with meteorites and reality? ----- Original Message ----- From: <MexicoDoug_at_aol.com> To: <mafer_at_imagineopals.com> Cc: <meteorite-list_at_meteoritecentral.com> Sent: Friday, September 23, 2005 1:27 AM Subject: Re: [meteorite-list] Fossils Offer Support for Meteor'sRoleinDinosaur Extinc... > Mark Fe wrote: >>Lack of a fossil means nothing. >>A charred bone fossil will. > >>Mark Fe "I've only driven through Missouri, but show me anyway" > > Hola Mark, List, > > 64.8 - 65.3 million years later and you expect to find a charred dinosaur > bone?
