well @historianmichael - you beat me to it - I was apparently posting at nearly the same time, but you were faster than me.

Standing:

@Ludwigia: 37 points.

@JamieLynn: 16 points.

@rocket: 15 points.

@Paleorunner, @Pleuromya: 9 points each.

@hemipristis: 8 points.

@Wrangellian: 6 points.

All other contributors 5 points or less.

Note: @Ludwigia has told me, that he will not accept any prize sent to him. So at the moment its up to @JamieLynn, @rocket, and some more contributors to get some ugly Kainach Gosau fossils.

 

Again catching a few points for myself .

Presenting "Fludergrabenmarmor". No, this is not a marble, but a usually coarse and quite tough limestone. Good stone, good workability, former used for buildings, slabs etc. Quite nice, too, with red-brown matrix and white spots. You may guess it: Its crinoidal limestone. Nearly 100 % crinoid debris, sometimes stem parts are preserved, but not much else. Some sites contain abundant brachiopods, but that´s a different story.

Officially, its "Hierlatzkalk" of the "Hierlatzkalk-Formation, age is Lower Jurassic, it follows - with a hiatus - after the Upper Triassic Dachstein limestone in the Northern Calcareous Alps of central Austria. 

This specimens has a freshly broken surface, self collected near an old quarry at Fludergrabenalm, Altausse, Styria, in 2016. Here is a link with some field pics:

As I like to take part of the contest but really do not need more fossils, I would love to pass it on to someone

Ooops! Looks like Mike beat me to it with that beautiful piece.

Pleistocene. 

The label is wrong. This is a muskrat.

And... I check in and we're back at the Precambrian again.  sigh

[JamieLynn]

@hemipristis If no one posts a Precambrian within 24 hours of the last fossil post.....move on to Cambrian! 

[Missourian]

Oh wait... Precambrian BIF (banded iron formation):

 

The clast is within a cobble found in an alluvial deposit along the San Juan River near Mexican Hat, Utah.

 

 

 

The rounded cobbles were sitting on a bench along the river:

 

 

 

The material in the cobble has gone through at least three, maybe four cycles:

 

1. Precambrian - Rock erodes to produce the sediment for the BIF

2. Precambrian/Paleozoic - BIF is eroded; fragments end up in a conglomerate

3. Neogene - Conglomerate is eroded; cobble makes its way down the San Juan River and is deposited in alluvium

4. Neogene - San Juan River forms canyon as region uplifts; alluvium erodes

OK here's one of my few Permian items.

Info from seller:

probably Anthichnium sp. (theoretical amphibian)

Lower Pemian: Lenoxian/Artinskian (~285my)

Sangre de Cristo Fm.

El Pueblo track site, Upper Pecos Valley, New Mexico.

I also have a conifer print and raindrops from this site, which I'll save in case there is a lack of Permian stuff later.

I love trace fossils and have a number from this site.

Triassic-

 

 

 

 

Here are a couple Jurassic pieces.
 

This is a piece that I purchased at an auction a few months back. Though these have been put together in this display, I still like them.

 

Russian Pyritized Ammonites

Mikhaylov, Russia

Upper Calloujan

Middle Jurassic

 

 

This is an older piece that I have had for about 25 years.

 

Belemnites

Germany

Jurassic

Cretaceous-

 

I picked up these pieces and a couple other things from this formation in Argentina about 30 years ago at a MAPS show that was held in Macomb, Illinois. The dealer was from Argentina and had so many great fossils, I wish I bought more at the time, but I figured that he would be back, but it was not to be.

 

 

Here is a piece that is not great, but I really love this wind blown sand polished dinosaur bone from the same formation as noted above.

 

 

 

 

Here are a couple of my favorite dinosaur pieces, Troodontid teeth from the Cretaceous of Alberta, Canada. (Named Edited)
 

(Frank @Troodon is it okay to ID them as this? I always call them Troodon teeth.)
