RescueMJ Posted March 17, 2021 Share Posted March 17, 2021 Supersized Tilly Bone? Looks like a Large Gummy Bear. Do you agree on the fossil? Not dense at all. Looks like a sample I have collected already...but this one is very large. 7 cm long, 4.2 cm wide This is a good reference piece. -Michael Link to comment Share on other sites More sharing options...
Rockwood Posted March 17, 2021 Share Posted March 17, 2021 Bone ? Yes. Vertebra ? Probably. Tilly ? I'm not so sure. Could be just not a fish. Link to comment Share on other sites More sharing options...
hemipristis Posted March 17, 2021 Share Posted March 17, 2021 I have a gray one very similar from Lee Creek, about 4 cm. It's currently labeled 'unknown'. Tilly or some type of tympanic bulla? Its stored away somewhere. I should have posted it here. Following this 'Those who cannot remember the past are condemned to repeat it.'

Mahnmut Posted March 17, 2021 Share Posted March 17, 2021 Hello together, interesting piece. the second pic looks very symmetric to me. I would say it is from the midline of the skeleton. I have found a recent tillybone of similar size from a catfish in 2019.

jcbshark Posted March 17, 2021 Share Posted March 17, 2021 I think you're correct on it being a tilly, I have a few just like it Every once in a great while it's not just a big rock down there! Link to comment Share on other sites More sharing options...
Harry Pristis Posted March 17, 2021 Share Posted March 17, 2021 It does have the look of a Tilly bone. MJ says that it is "not dense at all," and that is not a character of a Tilly bone, at least, not of the fossil examples with which I am familiar. 4 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...
RescueMJ Posted March 17, 2021 Author Share Posted March 17, 2021 Here is my comparison example which is not as big. This example is very dense. They are very similar in appearance though. Link to comment Share on other sites More sharing options...
Rockwood Posted March 17, 2021 Share Posted March 17, 2021 I'm afraid the density, just outweighs any similarity. I had seen it as porosity, but it's likely about the same measure. Link to comment Share on other sites More sharing options...
RescueMJ Posted March 18, 2021 Author Share Posted March 18, 2021 I’m out of town. I’ll add some better photos Friday. Regardless, pretty cool to see it at surface, brush a little, some more, and recover. Surprising what is under foot. Link to comment Share on other sites More sharing options...
RescueMJ Posted March 22, 2021 Author Share Posted March 22, 2021 Just for fun... I had my students assist with calculating density today. The results are in. Item that is topic of the post has a density of 1.27 g/cm3. The comparative sample I posted has a density of 1.895 g/cm3. Thanks for your interest. Look out for my next post on "Indian Artifact?" -Michael 1 Link to comment Share on other sites More sharing options...
