Troodon Posted April 10, 2017 Share Posted April 10, 2017 Boy this one has me stumped and I haven't got a clue what it is. From the late Jurassic of the Morrison Formation. I cleaned out the base and its a concave cavity. Any help pointing me in the right direction would be appreciated. Thanks 1 cm tall. 3 Link to comment Share on other sites More sharing options...
jpc Posted April 10, 2017 Share Posted April 10, 2017 Yikes... I saw the heading and I was hoping I could help you out for a change... but NO, this is weird. 1 Link to comment Share on other sites More sharing options...
LordTrilobite Posted April 10, 2017 Share Posted April 10, 2017 That definitely is weird. I'd say it looks like a kind of tooth with enamel on it. Maybe a fish tooth? Some fish have some seriously weird tooth morphology. 1 Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
FossilDudeCO Posted April 10, 2017 Share Posted April 10, 2017 Haha, I had the same idea as JP....interesting piece... 1 Link to comment Share on other sites More sharing options...
Troodon Posted April 10, 2017 Author Share Posted April 10, 2017 @jpc that's exactly what I said when I first saw it. @LordTrilobite that crossed my mind but I've never seen a tooth with this morphology but I'm clueless when it comes to fish. It does appear to have enamel on it and its size would not exclude fish. I will do some research thanks guys. Link to comment Share on other sites More sharing options...
Troodon Posted April 10, 2017 Author Share Posted April 10, 2017 @FossilDudeCO appreciate the look all I can ask for. Its definitely an odd ball Link to comment Share on other sites More sharing options...
ynot Posted April 10, 2017 Share Posted April 10, 2017 Just a wild thought, but could it be part of a crab? 1 Darwin said: " Man sprang from monkeys."

sagacious Posted April 10, 2017 Share Posted April 10, 2017 Looks a lot like either a conifer terminal bud (bud cap), or a male conifer cone. 1 Link to comment Share on other sites More sharing options...

Many have a resinous surface to protect against desiccation, insect damage, etc. The mineralization may just look somewhat enamel-like. 1 Link to comment Share on other sites More sharing options...
goatinformationist Posted April 11, 2017 Share Posted April 11, 2017 Maybe the surface is just agatized much as what I see in many coral fossil clusters. 1 Link to comment Share on other sites More sharing options...

Renaud Posted April 11, 2017 Share Posted April 11, 2017 It look like a turtle limb osteoderm as in Solemydidae. But I'm not sure. 1 Link to comment Share on other sites More sharing options...

Got Bones? Posted April 11, 2017 Share Posted April 11, 2017 This find resembles a Cycad species to me.

Fruitbat Posted April 11, 2017 Share Posted April 11, 2017 I was thinking that it might be an araucariaceous conifer seed cone as well. There are some silicified seed cones of that family found in the Morrison Formation. -Joe 3 Illigitimati non carborundum Fruitbat's PDF Library Link to comment Share on other sites More sharing options...
Troodon Posted April 11, 2017 Author Share Posted April 11, 2017 Thanks guys will add roses and conifers to my research list. Looks like we have a few members on the conifer track. Link to comment Share on other sites More sharing options...
ynot Posted April 11, 2017 Share Posted April 11, 2017 I disagree with plant as, in the first picture, there is no pattern/organization to the pimples. All of the plant buds I have seen have an organized repeating pattern. (Including the ones posted by Fruitbat.) Also there is no segmentation in the piece which I would expect to see in a leaf bud or seed cone. I still think it looks crustacean. 1 Darwin said: " Man sprang from monkeys."

Don RCR Posted April 11, 2017 Share Posted April 11, 2017 This looks a little like a horsetail cone. If it is, its the most beautifully, well preserved cone I've ever seen. 3 Link to comment Share on other sites More sharing options...

If crustacean, it should have an opening on both ends (unless it was a tip of a chela, which it doesn't appear to be). Crayfish are known from the Morrison. @Troodon, does the narrow end have an opening or is it enclosed entirely? 1 Link to comment Share on other sites More sharing options...
