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

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.

Thanks. 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

Never claimed this to be of Cretaceous age, there is a more recent formation above the layer of limestone. 

 

 

Your response to the question above ("Can you tell me what type of sediment layer these were found?") was....

I was just clarifying these did not originate in the "Cretaceous limestone".
