[Ludwigia]

From the Early Permian (so-called Permocarbon) Cisuralian Netzkater Formation at the Rabenstein Pit in Ilfeld-Netzkater, Saxony-Anhalt, Germany. Annularia sphenophylloides. The plate measures 8x5cm. Found myself on one of the spoil piles there in August 2004.

Smuggling in a few points for myself .

Another Monotis bivalve hash from the upper Triassic Hallstattkalk-Formation of the Northern Calcareous Alps of Austria.

Self collected from the driveway of a forest road about 7 years ago. Specimen has been freshly split after finding it.

Focus shift from ores and coals to fossils was nearly completed then. 

 

Standing is:

@Ludwigia: 15 points.

@JamieLynn: 9 point.

@Nimravis, @rocket: 5 points.

And 6 more contributor with 3 points or less.

Collected summer 1988 during geology field camp

Cretaceous, hmmmm

a nice branch of ?Brachyphyllum, approx. 7 cm wide nodule from upper lower cretaceous (Aptian) of Santana-Formation, Araripe-Plateau, Brazil. Plantes are rare in the nodules, most common is fish

3 samples of Ampullina sp. gastropods with a bit of whitish shell substance remaining on them. The largest on the left has a ø of 3.5cm. Found in the summer of 2012 while clambering about in the Kroisbachgraben in Salzburgerland, Austria with my friend Andreas Spatzenegger. From the Paleocene Olching Formation Oichinger Layers.

 

[Paleorunner]

From the Eocene Clavilithes sp.this 6.5 cm long gastropod, France. (It is the only information that the seller gave me).
Online purchase made at the beginning of this year.

A nice colorful piece of achatized coral from the Oligocene layers on the Withlacoochee river near Valdosta, Georgia which I recieved from my Secret Santa Mr.Fossil in 2018. It measures 7x5cm.

This is the Miocene (Langhian) gastropod Vitta picta, very kindly sent by FranzBernhard. It was a herbivorous intertidal gastropod, from the Florianer Schichten of Styria, Austria. It also has its original colours.

Beautiful colour patterns!

I agree, it's really impressive.

Looks like Clavilithes sp.

If it is, thanks for remembering. I will have to hit myself with a mallet on the head, I forgot to put the name when I published it. 
(I only have that information from the seller), he was referring to the origin, he only said that it was from France.

Nice pieces- here are a couple of mine.

 

The bird bone in matrix is from the same location as yours, but my other three pieces are said to have come from Maricopa Brea, but I cannot find any info on that.

 

Bid Bone- but I think it is mammal.

Middle Cambrian.

After prep : 

 

Oh, and my good friend @Paleorunner, your 'Orthoceras' from Morocco is an orthocerid but not Orthoceras, which is a Balto Scandinavian genus not found elsewhere. The Moroccan ones are usually Temperoceras ludense.

This is an indeterminate ptychopariid. Achlysopsis liokata  is known only from cranidia:

 

Type Species.—Achlysopsis liokata Fritz, 1968 from the Pioche Shale, East-central Nevada, by original designation. Remarks.—The extended, emended diagnosis is due to the plethora of ptychoparioids missing distinct character states that can be used to quickly identify them. The diagnosis does not include the pygidium due to the lack of fully articulated shields or monospecific assemblages that provide assurance that a pygidium belongs to the taxon. Fritz (1968) questionably assigned a pygidium to the type species and compared it to Tonkinella idahoensis Resser, 1939a.

Thanks for the information, "correction" 
Either the seller didn't really know what he was selling, or he fooled me like a fool......

No, my friend, the vast majority of people still think that these are "Orthoceras". 

Don't forget that most people; even dealers and most amateur collectors, don't know the difference between orthoconic forms, orthocerids and "Orthoceras". 

I'm sure it was an honest mistake.

Thanks for the clarification. 
Apparently, this type of orthocerids is very widespread, all the ones I have seen have been identified as Orthoceras from Morocco.....
