Chief1701 Posted April 9, 2019 Share Posted April 9, 2019 Hi, All. I don't have a clue what these are, but I'm guessing a bivalve of some kind? They came from the desert sand near Agadez, Niger, but that's all I know. The street merchant I got them from thought they were dino toes, but I'm guessing not.... The thing that confuses me the most (other than the fact that I haven't been able to find any pictures of bivalves that look like this) is that it doesn't look like the "shell" would actually close like a clam or mussel. Any and all help in identifying these would be most appreciated! Rob Link to comment Share on other sites More sharing options...

Chief1701 Posted April 9, 2019 Author Share Posted April 9, 2019 I don't think so.... At least, not in the pictures I can find on Google. Thanks for the suggestion, though! Link to comment Share on other sites More sharing options...
minnbuckeye Posted April 9, 2019 Share Posted April 9, 2019 Definitely a bivalve steinkern. I posted this yesterday to answer another form member's question under the topic "Please help ID Lower Ordovician fossil". The internal mold of a bivalve can look so strange at times. .

fossilnut Posted April 9, 2019 Share Posted April 9, 2019 Search Cucullaea on this forum for pictures that I believe match your 4th and 5th pictures. Common name is heart cockle-deer heart and in Myrtle Beach SC they call them turtle heads. Agreed it is a bivalve steinkern Especially see 'I found this today..." by Ssherrick on 8/28/18 1 Link to comment Share on other sites More sharing options...
Chief1701 Posted April 10, 2019 Author Share Posted April 10, 2019 I have been having no luck finding the Ssherrick on 8/28/18. I probably am not searching correctly.... Could you help me out with a link or page number? Thank you! Rob Link to comment Share on other sites More sharing options...

Fossildude19 Posted April 10, 2019 Share Posted April 10, 2019 These have been called Deer Heart clams, and Turtle Heads. Colloquial names for these types of steinkerns.

sixgill pete Posted April 10, 2019 Share Posted April 10, 2019 Cucullaea steinkerns. It is sediment that hardens inside of the shell then the shell dissolves away. The steinkern takes the shape of the INSIDE of the bivalve. Very common in many areas of the world. 1 Bulldozers and dirt Bulldozers and dirt behind the trailer, my desert Them red clay piles are heaven on earth I get my rocks off, bulldozers and dirt Patterson Hood; Drive-By Truckers May 2016 May 2012 Aug 2013, May 2016, Apr 2020 Oct 2022 Link to comment Share on other sites More sharing options...
Chief1701 Posted April 10, 2019 Author Share Posted April 10, 2019 Thank you all for the great information! Another thing I'm learning is that not all of the same type of fossil are going to look the same.... Soooo glad I stumbled upon this website!
