Gavin Posted February 3, 2019 Share Posted February 3, 2019 This was found on my property in Ellis county Texas. Ellis county has history of mammoth fossil and we might of thought this part is a piece of a mammoth tooth? Link to comment Share on other sites More sharing options...
KimTexan Posted February 3, 2019 Share Posted February 3, 2019 It is an Inoceramus clam shell fragment. it looks like Austin Chalk formation material. The Austin Chalk is loaded with those clams. I’ve found some that were in excess of 4 feet across. 4 Link to comment Share on other sites More sharing options...
Gavin Posted February 3, 2019 Author Share Posted February 3, 2019 Yeahhhh, most likely, you don't always find mammoth teeth in your yard we we're just making the best of the situation, lol Link to comment Share on other sites More sharing options...
DevonianDigger Posted February 3, 2019 Share Posted February 3, 2019 +1 for Inoceramus As far as I'm concerned it doesn't matter what fossil it is. If you're finding it in your own backyard it's awesome! Jay A.

KimTexan Posted February 3, 2019 Share Posted February 3, 2019 It would be helpful to learn your formations and geological periods. It has helped me a lot. It takes time to learn though and you have to have something to help you along. My favorite tool is the Mancos iPhone app. If you don’t have an iPhone there is also the Rockd app, but Mancos far outweighs Rockd in terms of functionality and usefulness in my opinion. Mammoth would not have been found in the Cretaceous. They were found in the Cenozoic era predominantly in the Pleistocene, but I believe existed into the early Holocene. The clam is from the Austin Chalk which is in the upper Cretaceous. The Austin Chalk correlates with the European stages of Conician, Santonian and the lower Campanian. These may be helpful to you. This one is specific for the Texas Cretaceous. 3 Link to comment Share on other sites More sharing options...

DevonianDigger Posted February 3, 2019 Share Posted February 3, 2019 Sorry, I thought that would be an image when I posted it. Check out this reference on the geologic time scale. Even though I don't like to use Wikipedia as a reference, this seems to do a pretty good job of covering it: https://en.wikipedia.org/wiki/Geologic_time_scale Jay A.

DevonianDigger Posted February 3, 2019 Share Posted February 3, 2019 The short answer is that the Cretaceous period was the time period from roughly 145 million years ago up until approximately 65 million years ago.
