Moroccan Trilobite

[trilospain]

Hi all

This trilobite is from the Cambrian of Morocco.

It could be a Fallotaspis but I am not sure.

Any help is welcome.

Thanks in advance

hi trilo spain,

i think it resembles this one rather well:

I am not a trilobite guy by any means, but they do not look that similar to me.

Hi Trilospain,

I'm inclined to agree with you that it's a trilobite from the Order Redlichiida.

The narrow form and obvious diagnostic features suggest a Fallotaspis type genus.

In recent years so many new discoveries have emerged from the region making it

difficult to say which species without the contemporary papers in hand.

Eofallotaspis prima

Eofallotaspis tioutensis

Fallotaspis bondoni

Fallotaspis inexspectatus

Fallotaspis longispina

Thanks for your reply.

It must be from Zagora Region, but it's difficult to know detailed information about the origen of Moroccan trilobites. Your reference is very interesting because they are not too much papers about them.

I think in cases like that knowing the family (Fallostapidae) is a success.

Thank to all for your help.

Hi Jenaro,

I carelessly omitted Fallotaspis acuta from the list.

Here is a more recent publication, hopefully this can easily be sourced by you.

If you can't locate this publication send me a PM message and I'll try to help out.

My friend most likely has this but he's on holiday now for the next week or so.

Hi Janero,

Instead of waiting on my friend I contacted Professor Gerd Geyer directly. There might be a pdf forthcoming but not available yet. Your trilobite is not a fallotaspidid genus, although as predicted it is within the Order Redlichiida and not to far off however, actually very close by it's an olenid.

Gerd Geyer:

"In general, determining not very well preserved specimens of Fallotaspis from the western Anti-Atlas is tricky. However, the photograph which you attached is not a Fallotaspis but a late juvenile specimen of Hamatolenus (Hamatolenus) vincenti from the early Middle Cambrian Jbel Wawrmast Formation. The mode of preservation indicates that it almost certainly comes from the east-central Anti-Atlas of the Tarhoucht area."
