I am trying to get my fossil collection photographed.  I have more trilobites than anything else, so to light a fire under this ever delayed project, I'm going to post a new bug in my collection each week.

 

To start off, here is a plate of Primaspis crosotus trilobites from the Kope Formation.  These are itty bitty bugs, but show all the typical Ondotopleurid features -- pleural and pygidal spines all around, and fringes of short spines on the free cheeks.

Nice one. Is that a crinoid stem at the top? Collapsed in on itself?

I hope you add each week's new bug to this topic so I won't miss any of them.

That is a bit of crinoid stem.  I don't think it's folded over, I believe that's just how that stem looks.  And there's a tiny brachiopod next to one of the bugs.

Trilobite #2.  Much of modern paleontology started in the United Kingdom, but I have only a few U.K. bugs.  Here's one.  Ogyginus cordensis, a Middle Ordovician asaphid from Wales:

Trilobite #3:  Selenopletis gallica.  These Early Ordovician trilobites are from the Upper Fezouata Formation near Mecissi, Morocco.  As with many Moroccan trilobites these are given the same name as a European species, in this case, Selenopeltis gallica from Iberia, and will be called this unless and until a formal description is done, which might wind up assigning a different species and/or genus to these bugs.

There are going to be two bugs this week, both humble Proetids.

Trilobite #4.  Gerastos granulosus.  This is a common Middle Devonian trilobite.  This specimen came from Foum Zguid, Morocco.

What the heck -- I'm doing three trilobites this week, all humble Proetids.  Trilobite #5 is a species of Pragoproetus from Tafroute, Morocco.  It is Early Devonian (Pragian stage) in age.  If someone here knows which species within the genus it is, I'd like to know.
