Here is a detailed example of a relative rare Trilobite from Gees of the species Cornuproetus cornutus. Prone would the Trilobite be about 30 mm long,

Here is a nice regular see urchin from the upper Cretaceous of Morocco.
This specimen of Goniopygus coutini offers a very detailed surface preservation.

Here is a enrolled "Ohio Trilobite" of the species Flexicalymene meeki in a remakkibile size. Prone would the trilobite may be more than 60 mm long.

This "Ordovician Trilobite" from Morocco is a interesting example of Flexicalymene ouzregui that shows the hypostome.

Here is a inexpensive raw "Morocco Trilobite" that likely belungs to the genus Diademaproetus sp..
This is a good piece to gain practice in the fossil preparation of "Morocco Trilobites". One small chip is missing at the base of the right genal spine.
So the trilobite seems to be all most complete but the base of the right genal spine is defiantly missing.

Here is a inexpensive example of a "Morocco Trilobite" of the species  Diademaproetus antatlasius.

Here is a nice "Utah Trilobite" of the species Elrathia kingi.
The is a small meraspid stage of Elrathia kingi in front of the cephalon of the adult trilobite.

Here is a Eifel Trilobite of the species Gerastos cuvieri.

Here is a inexpensive example of a relative rare trilobit of the species Gerastos lisarasus from the Ceratages couche  of Zireg.

Here is a very detailed trilobite of the species Scabriscutellum hammadi on a nice shaped matrix.
The trilobite would be about 48 mm long, if it would be prone.

This is a excellent trilobite of the relative rare species Reedops bronni.
The completely enrolled trilobite offers a very detailed preservation and shows nicely on the  matrix. The naturally shaped matrix shows well the lithological features of the  Kohlihapeltis couche at  the Atchana site.

Here we have a nice "Nevada" Trilobite of the species Olenellus gilberti  from the lower Cambrian Pioche shale formation near Lincoln Country.

This is a detailed Trilobite of the species Coltraneia oufatenesis in a nice preservation.

This is a nice multiple piece with the trilobite Gravicalymene arcuata from the "Upper Ordovician" of Wales.

Here is a large trilobite of the species Reedops cephalotes hamlagdadianus from the Mdâouer-el-Kbîr site. Completely prone would the trilobite be about 86 mm long.

Here is a small trilobite example of the speciesBergamia prima from Shropshire.

Here is a upper Cambrian Trilobite from Wales of the species Parabolina spinulosa.

Here is a inexpensive example of a interesting scutellid trilobite of the genus  Scabriscutellum.
The trilobite was found at the "Psychopyge couche" of Jbel Issoumour.

Here is a unusual large "Eifel Trilobite" of the species Geesops schlotheimi from the classical site of Gees. Prone would this trilobite be about 50 – 60 mm long what is a remarkibile size for the "Devonian Trilobite Locality" of Gees. 

This is a inexpensive "Eifel Trilobite" of the species Cyphaspis ceratophthalmus from Gees. Prone would the trilobite without the species about 19 mm long.

Here is a nice and relative rare trilobite of the genus Leonaspis from the Eifilian of Morokko.

Here is a prone Trilobite of the species Boeckops stelcki from the "Tazoulait Formation" of Jbel Oufaten in Morocco.

Here is a fossil fish of the species Knightia alta  from the "Green River Formation" of Farson in  Wyoming.
