32fordboy Posted July 24, 2010 Share Posted July 24, 2010 (edited) Here's a Columbian mammoth molar that looks deformed-not sure if it is, though. Instead of being slightly convex across the top, it is very much concave. A picture of a normal Woolly mammoth molar is also attached for comparison. EDIT: it is supposedly from a Columbian mammoth, but I'm not sure-the scales look too wide.

megateeth Posted July 24, 2010 Share Posted July 24, 2010 These are a few of mine. I have 8 posted in the center of this page http://www.megateeth.com/sharkteeth.php My Favorite Patheo. This one measures 5.85" long. I thought it was broken when I first found it. Another cool one. Megateeth Fossils - Megalodon Teeth, Other Shark Teeth and Info about Megalodon shark tooth collecting.

Northern Sharks Posted July 25, 2010 Share Posted July 25, 2010 Another one for you: a Flexicalymene retrorsa with a bryozoan on its eye. I did not take the pics.

32fordboy Posted July 25, 2010 Share Posted July 25, 2010 Yep, not technically a pathology, but it seems to fit This thread is full of all kinds of neat oddities.

PrehistoricFlorida Posted July 26, 2010 Share Posted July 26, 2010 Sorry for the poor pictures, had to take them indoors with the camera flash. This is the worst pathology that I've seen in quite some time. This is an impacted mastodon or mammoth tusk. This is a nearly complete tusk from a full grown proboscidean, problem is, instead of being 7-10 feet long, it's only 19" long. This tusk is extremely deformed with all kinds of weird growths, it almost looks like a massive coprolite!! Nasty!! 3 www.PrehistoricFlorida.com Link to comment Share on other sites More sharing options...
tracer Posted July 26, 2010 Share Posted July 26, 2010 that is extremely interesting. how were you able to tell what it was? Link to comment Share on other sites More sharing options...
JohnJ Posted July 26, 2010 Share Posted July 26, 2010 Nate, that looks like a nasty infection...might have led to the animal's death. Would love to see some "daylight" photos.

32fordboy Posted August 9, 2010 Share Posted August 9, 2010 There's another paper somewhere that talks about tuberculosis in mastodon bones (apparently it effects the bones?). The guy doing the research said more than 50% of the bones he looked at showed signs of tuberculosis. If that's true, it wouldn't have helped the mastodon (and probably other animal) populations at the end of the Pleistocene. Supposedly, the study is highly controversial with plenty of other paleontologists calling BS. www.nicksfossils.com Link to comment Share on other sites More sharing options...

brachiomyback Posted August 11, 2010 Share Posted August 11, 2010 Here is one I found in a creek in Summerville, SC. Still not sure what the ID is. Enjoy.... Link to comment Share on other sites More sharing options...
Roz Posted August 11, 2010 Share Posted August 11, 2010 I am not certain of the specimen either but I really, really like it.. Bet someone knows the ID too.. Is that area Cretaceous or younger? I wish I would find more pathological fossils. I have a real fascination with them.. Welcome to the forum! Link to comment Share on other sites More sharing options...

THobern Posted August 11, 2010 Share Posted August 11, 2010 I believe it is from the Chandler Bridge Formation, Oligocene Epoch (approx 28 mya) Likely a Carcharhinus sp., but it's so hard to be sure with pathologies like that. Link to comment Share on other sites More sharing options...

Harry Pristis Posted August 12, 2010 Author Share Posted August 12, 2010 Here is another pathological bone. This one is a diseased osteoderm from a fair-size 'gator. The bones in the image are well-mineralized. In the diseased specimen the central boss is barely distinguishable. In the normal osteoderm of roughly the same size, the central boss is knobby with some wear after death, I think. Compare the pitted surface of the normal bone to the distorted surface of the diseased bone. Note also the difference between the undersurface of the normal example and that of the pathological example. 1 http://pristis.wix.com/the-demijohn-page What seest thou else In the dark backward and abysm of time? ---Shakespeare, The Tempest Link to comment Share on other sites More sharing options...
Roz Posted August 12, 2010 Share Posted August 12, 2010 I see huge differences.. The underside is so distorted, almost not recognizable. Makes me wonder if he was in pain but I don't know how alligators were wired as far as nerve endings go.. Welcome to the forum! Link to comment Share on other sites More sharing options...
