A fossil friend of mine on the Fossil Forum, Jason Rice, recently sent me a package of goodies in trade for some spare material I had on hand from Arkona.
The top row has some mouth plates and shells, while the bottom four rows are all fossil shark teeth. These are quite special for me as they represent the first shark teeth in my expanding collection. These are from the Miocene period, 6-20 million years ago.
The teeth are definitely worthy of a close up image.
This large fossil scallop is Chesapectens nefrens - a fairly popularly sought out one.
The trilobite Elrathia kingii from the Wheeler Formation in Utah. Middle Cambrian (~550 million years ago).
Another Asaphiscus wheeleri, with impression. It is fairly common that one finds these without their cheeks as they moulted their old carapaces and exited through their cephalons.
The most iconic of the Utah trilobites, and the one you see most commonly sold in rock shops, here we have Elrathia kingii with a tiny friend - a "mini-me" version, if you will.
All very exciting stuff! Not only does this boost my trilobite species count for the year, but particularly Cambrian trilobites (see my post on the ones I acquired from Marcus here). As there are no Cambrian exposures anywhere near me, these are a real treat.
