D.N.FossilmanLithuania Posted December 4, 2017 Share Posted December 4, 2017 Dear Guys, I recently found one small (5 mm width) and interesting specimen that can belong to primitive xiphosuran by the appearance of cephalothorax. It has not any jaws as trilobite and the preserved eye is merostomate like (not any small eyes but only protuberant area, similar to eurypterid or other chelicerate eyes). The rick is found in Varena town, South Lithuania and the age should be about 475 million years. Please help to confirm the primitive chelicerate if you could.

D.N.FossilmanLithuania Posted December 5, 2017 Author Share Posted December 5, 2017 Dear JohnBrewer, thank you for better picture. Do you agree with determination, or could it be something other? Regards Domas Link to comment Share on other sites More sharing options...
Rockwood Posted December 5, 2017 Share Posted December 5, 2017 From personal experience with eurypterids, my thought is that the preservation is wrong. This looks like a more substantial material to me. Link to comment Share on other sites More sharing options...

Cowboy Paleontologist Posted December 9, 2017 Share Posted December 9, 2017 I don't know, looks kind of trilobity to me... It is hard to tell since it is such a small piece, but could it be a lobe from the glabella of a trilobite rather than an eye? I am no expert by any stretch of the imagination, but that's what it reminds me of. 1 Link to comment Share on other sites More sharing options...
Tidgy's Dad Posted December 9, 2017 Share Posted December 9, 2017 Yup, looks like a trilo glabella part to me as well. 1 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
D.N.FossilmanLithuania Posted December 9, 2017 Author Share Posted December 9, 2017 Thank you very much! Maybe Nileus?? Link to comment Share on other sites More sharing options...
FossilDAWG Posted December 9, 2017 Share Posted December 9, 2017 Definitely a trilobite cephalon. Nileus is one possibility, but I don't see enough to exclude other bumastids. Don Link to comment Share on other sites More sharing options...
