austinswamp Posted December 28, 2019 Share Posted December 28, 2019 Hello I was hoping to get an ID on this jaw to help clarify the particular age of a layer that is eroding away currently in Dallas County, North Texas. Thank you Link to comment Share on other sites More sharing options...
austinswamp Posted December 28, 2019 Author Share Posted December 28, 2019 This scute also came from the same layer...looks like it could be box turtle of soft shell turtle Link to comment Share on other sites More sharing options...
caldigger Posted December 28, 2019 Share Posted December 28, 2019 The jaw looks like it might be something like muskrat or similar critter. Link to comment Share on other sites More sharing options...
Misha Posted December 28, 2019 Share Posted December 28, 2019 To me the jaw looks more like a hare or rabbit, I am not sure about the second item. 1 Link to comment Share on other sites More sharing options...
Al Dente Posted December 28, 2019 Share Posted December 28, 2019 The second item might be part of a soft shell turtle carapace. Link to comment Share on other sites More sharing options...

Creek - Don Posted December 28, 2019 Share Posted December 28, 2019 Can you tell me what type of sediment layer these were found? In Dallas county there are several layers, cretaceous (limestones), Pleistocene ( limestone gravel layer), light clay and then modern dark soil layer that are recent. I usually don't find anything above the Pleistocene layer though. Link to comment Share on other sites More sharing options...

When you find mammal bones closer to limestone layer in Dallas county, they are most likely a Pleistocene mammals. Those bones are probably thousands of years old.

Well this can be subjective, if a prehistoric person placed the animals out of context Link to comment Share on other sites More sharing options...
JohnJ Posted December 29, 2019 Share Posted December 29, 2019 @austinswamp Based on your photos, your finds are not Cretaceous age bones. 1 The human mind has the ability to believe anything is true. - JJ Link to comment Share on other sites More sharing options...

austinswamp Posted December 29, 2019 Author Share Posted December 29, 2019 Never claimed this to be of Cretaceous age, there is a more recent formation above the layer of limestone. Link to comment Share on other sites More sharing options...
