Here is another green 'Mary Ellen' stromatolite slab from Minnesota

Sweet!

And that´s what I would like to call dedication: Flooding the scanner to show off a good fossil !

In lieu of polishing the slab, I have a clear, semi-stiff plastic sheet to protect the scanner bed. Just a little puddle of water on top of this is all it takes to wet the whole slab face.

Precambrian from Poland - they look quite like Nemianas from Ukraine, but I have never subjected the pieces to any expert assessment, so I stick with precambrian

[rocket]

I add a nice walking-group of Amphyx-Trilobites, Ordovizium, Zagora / Morocco. Each one has all spines (some are not complete) and has a length without spines of approx. 2 cm

 

 

[Pleuromya]

Here are the fossils in the prize.

I will try and add more things at some point, probably some more Rhaetian material. 

 

 

The Wren's Nest is an SSSI in Dudley, West Midlands, UK. It's the remains of a Silurian Coral reef environment and was the UK's first geological nature reserve. 

 

These are the fossils from Wren's Nest. 

 

Atrypa regularis brachiopods 

 

 

Rhynchotreta cuneata brachiopod, this measures about 9mm across.

 

 

Sphaerirhynchia wilsoni brachiopod

 

 

Howellella elegans brachiopod 

 

 

I think these small brachiopods are Microsphaeridiorhynchus nucula, but I'm not sure. 

 

 

Two Favosites corals

 

 

A Rugose Coral

 

 

A piece of the Wenlock Limestone. 

 

 

Some bryozoans, unfortunately I've only found them fragmentary like this.

 

 

The Rhaetian material is from Aust Cliff in Gloucestershire, UK. The Westbury bone bed was formed in a shallow sea or coastal lagoon. It likely had an anoxic ocean floor, which allowed coprolites to be preserved. There's currently three pieces, but I will try and add more soon. 

 

 

 

 

 

I had a quick look, there's several bone fragments and they all contain multiple coprolites. I also took a few photos with magnification. 

 

I think this tooth is from the shark Rhomphaiodon minor.

 

 

This is a Lissodus minimus tooth adapted to crushing molluscs. Lissodus was about 15cm long. 

 

 

A Birgeria acuminatus tooth

 

 

And a Gyrolepis albertii scale.

 

 

Aside from these, there's lots of tiny teeth and fish scales. 

I'm not entirely certain with the identifications, so please let me know if any are incorrect.

Ooh, the entries are going to come fast and furious now...

[hemipristis]

Fossils from the Red Hill site, Devonian, Clinton County, Pennsylvania, USA

 

First: 2 placoderm scutes and a tooth (circled) from unknown

Early shark, Ageleodus pectinatus

[hemipristis]

A nifty fossil hash of spines, scales, scutes and ?

[Paleorunner]

It seems to me that we are skipping the order of the periods. We have passed from the Precambrian to the Ordovician, and then to the Devonian.
We should keep the order in the periods, or else this thread will become crazy... 

 

Before continuing with the Carboniferous, please post Cambrian, and Silurian.

[Paleorunner]

I will add the Cambrian.
Here an early Cambrian arthropod. Isoxis curvirostratus. 2.5 centimeters. Yunnan-China.

 

 

[hemipristis]

Pleurisy's fossil menagerie was stated as coming from a Silurian reef,   We may have missed the Cambrian though.

 

Looks like we are all caught up now.

Perhaps the publication of the gift of @Pleuromya has caused confusion, I understood it as a publication of the award, not as the next period, if I was wrong we would continue with the Carboniferous.

[Pleuromya]

Yes, sorry it was just the award rather than the Silurian.

oops

[Kane]

I'll handle the backfill.

 

Cambrian: Itagnostus interstricta, Utah, Wheeler Fm

Silurian: Calymene breviceps, Indiana, Waldron shale. 

[FranzBernhard]

LOL!

That´s quite a job now for @Pleuromya to distirbute, aehhh, distribute the points correctly !

Ongoing with Caboniferous!

Gotta love an edestus

That's true 

I will count the points at the end of the round

Pieces of Mycterosaurus longiceps, Permian, US

[Top Trilo]

Despite what @FranzBernhard says, his fossils are really cool, I'm lucky enough to own a few. This one is an ammonite from the Hallstätterkalk Formation, Carnian aged, Late Triassic. The entire piece is about 6cm across. I like how the unique cross section along with a part of the whorl is visible on the side. And the red and yellow color combination is another added bonus, thank you Franz.

Thanks, but I don´t have that stuff any longer. I have turned to other areas with really ugly fossils. Believe it or not .

[Ludwigia]

So since we've once again arrived at my Jurassic area of specialty, I'll add a Serpula convoluta from the humphriesianum zone in Geisingen, Germany.
