M Harvey Posted February 7, 2021 Author Share Posted February 7, 2021 (Having trouble adding text). This is something I found in a creek gravel bed in central Alabama. It has me stumped and wonder if it is recognizable to anyone. Could be Cretaceous, Paleocene, or Pleistocene. The break is colloidal and reminds me of obsidian. Any thoughts?

Shellseeker Posted February 7, 2021 Share Posted February 7, 2021 It would be easier if you got rid of much of the extra space. I try to make the fossil fill 70-80 % of the photo.... I am wondering if (outside the ring) that darker material is enamal making it tooth or tusk... and that globular core reminds me of walrus... Likely need crisper closeups of the "enamel" and the globular core The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

I will try to submit a better photo. Link to comment Share on other sites More sharing options...
Shellseeker Posted February 9, 2021 Share Posted February 9, 2021 So if you search this forum, you will find threads like these http://www.thefossilforum.com/index.php?/topic/60609-possible-tusk-fragment/ and photos like these: In a walrus tusk , there is the outer ring of ivory and a inner globular dentine core.. Your photo seems to have outer enamel and inner globular core... 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...
Shellseeker Posted February 9, 2021 Share Posted February 9, 2021 Just adding the fragment of a walrus tusk, I thought was somewhat similar. 1 The White Queen ".... in her youth she could believe "six impossible things before breakfast" Link to comment Share on other sites More sharing options...

M Harvey Posted February 9, 2021 Author Share Posted February 9, 2021 I think it is a possibility. It certainly has flint characteristics. It's the pattern that has me puzzled. It looks biological to me. Link to comment Share on other sites More sharing options...
