Keeping with otodus, otodus soklovi from the Oligocene of khazakstan

And from the Miocene of my city, the internal mold of this gastropod.

                             

                                       (Xenophora Infundulum).

This is a fun thread. Here's a tiny one from the Pleistocene.

That is an awesome trilobite!  What country was that found in?

Aha we meet again

SEM micrographs of chitinozoa (Conochitina spp?) from the middle Silurian Manistique Group of Michigan 

 

[fossilsonwheels]

Not a great picture as it’s a very small tooth but a pretty rare Devonian shark tooth, Wellerodus priscus from Logan Ohio. 

[Misha]

Here's a big and beautiful Athyris llamelosa, from the Mississippian Spickert Knob Formation in Indiana

Well, well, I will present not a fossil in my collection (I have no Permian fossil), but the Permian petrified forest in Carinthia, Austria. Homepage only in German, unfortunately:

Petrified Forest of Laas (Geopark Karnische Alpen)

Feel free to present also a "real" Permian fossil specimen . Or go on with the Triassic .

[piranha]

Sclerocephalus haeuseri  52cm – Lower Permian – Pfalz, Germany

 

[Ludwigia]

Arcestes cf. opertus from the Middle Triassic Karnian from Millibrunnkogel/Vordersandlingalm, Hallstatt, Salzburgerland, Austria.

 

[Ludwigia]

I suppose I could also carry on with the Jurassic. This time from the Late Pliensbachian. A Pleuroceras sp. with pyrite from the site in the Goldbach near Reichenbach/Aalen.

 

[fossilsonwheels]

A rare Cretaceous example of an extant Squaliformes genus, Centroscymnus  from Hornsby Island BC. 

[fossilsonwheels]

I know from going through this thread that the Paleocene is one that slows the thread a little bit so here’s a Paraorthacodus clarkii from the Aquia Formation.

@piranha that amphib is in your collection?? I am totally jealous.  I love it.

Yep...thanks!

[MeargleSchmeargl]

Guess I may as well toss in one of my better Periarchus pileussinensis sand dollars from the Tivola Limestone of the Late Eocene. 10/10 one of my favorite formations to collect from now.

 

[FranzBernhard]

Something Oligocene out there ?

Many thanks!
