Haravex Posted July 19, 2018 Share Posted July 19, 2018 Recently picked up some un-prepared trilobites while in morocco there is some Cambrian trilobites pictured here which have not had the full prep done yet so I understand some might not be fully identifiable.

Kane Posted July 19, 2018 Share Posted July 19, 2018 I’ll wager a guess... Hamatolenus sp. (possibly Hamotolenus marocanus) . ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Haravex Posted July 19, 2018 Author Share Posted July 19, 2018 Is that the first one? They all look different to me but again have very little knowledge on these fossils. Link to comment Share on other sites More sharing options...
indominus rex Posted July 19, 2018 Share Posted July 19, 2018 Those are some really awesome trilobites. I am no expert but I'll also try a guess, the one before the last one looks to me like a Ourikaia Calva. Also may I ask what are their sizes? I think that @LordTrilobite would be able to help, after all he is the lord of trilobites. Life started in the ocean. And so did my interest in fossils.

LordTrilobite Posted July 19, 2018 Share Posted July 19, 2018 Sorry, no idea. Haven't focused on trilobites in over a decade. Olof Moleman AKA Lord Trilobite Link to comment Share on other sites More sharing options...
Haravex Posted July 19, 2018 Author Share Posted July 19, 2018 The 1st is 1.9 inches head to tail (pygriym?) 2nd is 2.3 inches 3rd is 0.7 inches 4th is 0.8 inches and the 5th is 2.0 inches. Link to comment Share on other sites More sharing options...
Kane Posted July 19, 2018 Share Posted July 19, 2018 I'm thinking they may all be Hamatolenus (not Ellipsocephalus) Here is an image of Hamatolenus marocanus for comparison. Note the similar shape of the glabella to your specimens: ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Haravex Posted July 19, 2018 Author Share Posted July 19, 2018 It looks like it but the first one does seem different the side spines of the head extend all the way to around 2/3rds of the body. Link to comment Share on other sites More sharing options...

Have a look here. It seems that there is some variety in how these trilobites are named. In this case, the convention sides with Hamatolenus marocanus. In the images here, you can see some of the specimens have long genal spines: http://moroccan-trilobites.net/h.marocanus.html ...How to Philosophize with a Hammer Link to comment Share on other sites More sharing options...
Haravex Posted July 19, 2018 Author Share Posted July 19, 2018 Ah ok thank you for this I still do wonder if the first one is slightly different maybe its from the same hamatolenus family but a different type from this genus? Again know very little about these bugs but wanted to give people a chance to pick one or two real Cambrian trilobites as I see this posted a lot in the is it real section of the forum. Thanks for all your help Kane Matt Link to comment Share on other sites More sharing options...
Kane Posted July 19, 2018 Share Posted July 19, 2018 Could very well be. I'll have a look at some of the diagnostic details of the Hamos listed in Morocco. Some I can rule out (such as H. vincenti) because yours don't seem to have a macropleural spine present.

Haravex Posted August 1, 2018 Author Share Posted August 1, 2018 There is also this one that I am currently prepping but don't know the species and would be good to know so I have an overall idea of where parts of the head are as I see some trilobite from morocco that sometimes have additinal parts to the head like spines and stuff like this.
