JojoMozza Posted July 21, 2017 Share Posted July 21, 2017 Hi all, I've this nice Moroccan trilobite. The seller did not know what genus or species it was. I have an inkling that it is Scabriscutellum, though could be wrong. Can the genus or species be pinpointed? Thank you! Jojo Link to comment Share on other sites More sharing options...

RyanDye Posted July 21, 2017 Share Posted July 21, 2017 Nothing can be completely 100% confirmed from my conjecture until some more experienced eyes look at it but, I would bet money on it being Scabriscutellum furciferum. Hope this was right and turns out to be helpful. http://www.trilobites.us/corynexochida/scabriscutellum-furciferum/scabriscutellum-furciferum.htm 1 Link to comment Share on other sites More sharing options...
JojoMozza Posted July 21, 2017 Author Share Posted July 21, 2017 Thanks @Ryan Dye It looks very similar, especially the thorax and pygidium. But I don't know about the cephalon. It looks a little different?......I'm not sure. You're probably right though; may just be the position. Cheers, Jojo Link to comment Share on other sites More sharing options...

Cheers, Jojo I see what you mean I actually found a couple images that resemble yours even more but, they were all unidentified species. Here's one of them.

RyanDye Posted July 21, 2017 Share Posted July 21, 2017 The matrix in this one resembles your specimen more. Click Here. Link to comment Share on other sites More sharing options...
JojoMozza Posted July 21, 2017 Author Share Posted July 21, 2017 Thank you so much @Ryan Dye! I had a look at the link and the matrix definatley is very similar. The other photo looks almost identical, would you say that it is 100% Scabriscutellum? It so, I guess I'll have to just label it as Scabriscutellum indet. Thanks again, Jojo Link to comment Share on other sites More sharing options...

Thanks again, Jojo If even one more person is to agree with me I think that should be enough to completely confirm it. Link to comment Share on other sites More sharing options...

That colour is just the result of the air scribe hitting it (thats a bad way of explaining it) 1 Link to comment Share on other sites More sharing options...

Not that you were trying to disprove me I just wanted to reaffirm my conjecture. Link to comment Share on other sites More sharing options...

Thats the only non time consuming way to prepare those fossils. the matrix is very very hard, and definitely would not have split as easy as, say shale, and still kept the trilobite intact, if that makes sense Link to comment Share on other sites More sharing options...

JojoMozza Posted July 21, 2017 Author Share Posted July 21, 2017 Ah yes, forgot about the air-scribing. Moroccan trilobites; the matrix is very hard - almost like concrete. Do you reckon there has been any restoration? Link to comment Share on other sites More sharing options...
