This decorative piece from the Eocene of Damery shows two gastropods together with a nice bivalve. 

This is a remarkably  large fossil example of a gastropod of the species Athleta spinosa from the Lutetian  of  Damery.

This is a relative large fossil gastropod of the species Clavilithes parisiensis from the Lutetian  of  Damery.
The fossil  gastropod is about 53  mm long.

This is a large fossil bivalve of the species Crassatella ponderosa from the Lutetian  of  Damery.
The fossil  bivalve is about 68 mm wide.

Here is a decorative piece from the Eocene of Damery,  in France.

Here is a decorative "Solnhofen Ammonite" from the lithographic limestone of Eichstätt..

This is a good "Morocco Trilobite" of the species Leonaspis issoumourensis

Here is a fossil example of a mimosa of the species  Mimosites coloradensis   from the "Green River Formation" of Utah.

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.
