I found this Trigonia costata bivalve on May 12th during a paleontological excursion to a site called the Kahlenberg in Ringsheim in the Rhine Valley in southwestern Germany. It has both valves intact and is extremely well-preserved, which is why I've decided to take part in this contest again after a long absence. Preparation time was about 2 hours and it was finished on May 17th.

Stratigraphy: Middle Jurassic, Early Bajocian, Humphriesi-Oolite Formation, humphresianum zone. It measures 6x4.5cm.

Found: April 29, 2018

Name: Eldredgeops rana

Age/Formation: Mid Devonian, Moscow Fm

Location: Western NY

 

A common bug, but a decent size for this location (4.6 cm). Preparation performed on May 5 and 6. Was found cleaved in two, secured with glue. Missing a few pleural shell parts from initial fracture.

I like the aesthetics of the little brachiopod impression on the bottom right there. It gives it a sense of being in its natural surroundings/habitat. 

Very nice.

Thanks! :) I hadn't actually noticed it until you pointed it out. To my shame and discredit, I blitz off a lot of brachs during prep when I am focused on the bug. :blush:

This is a very stiff competition this month in both categories. Come time to vote I might be flipping a coin.

@Ludwigia that is, I'm pretty sure, the BEST trigonid I have ever laid my eyes upon... Simply: WOW! :envy::wub:

@Kane That Eldredgeops rana is wonderful! 

Opalised fossils are the best: a wonderful mix between paleontology and mineralogy!

 

Q. Where do dinosaurs study?

A. At Khaan Academy!...

Every single fossil you see is a miracle set in stone, and should be treated as such.

With all of the wonderful submissions so far, I know I haven’t got much of a chance but I’m going to enter anyway because it’s fun! This wasn’t my largest Neptunea, but I really liked the “folded” (I don’t know the proper word for it) look of the shell towards the bottom. Without further ado, I present:

Amazing finds!  With much humility, I am entering the largest regular shark tooth I have ever found.

First photo is before. Others are prep and final conditions.

 

This tooth is a 47mm diagonal by 42mm root width in nearly flawless condition on the backside. But, the front side has begun to weather out on the root.  I may try to prep the front more, but I don't want it to come off of the rock matrix. The tooth has curvature into the hole in the rock. From my experiences, they usually aren't this wide and massive. 

 

 

Date of Discovery:  May 19, 2018

Scientific Name: Cretodus crassidins

Geologic Age & Formation: Cretaceous, Turonian, Eagle Ford Formation, Bouldin Flags Member

State or Location of Find: Travis County, Austin, Texas USA

That is astonishing! Great find. Wouldn’t want to get in that shark’s way. What tools did you use to prep it?

The staff has discussed this, and we are allowing the entry.

Tried first with ice pick type tool, but matrix was way too hard.  Went to ARO Model 8315 air scribe that I acquired several years ago put inside a cheap sanding cabinet from Harbor Freight with a Porter-Cable 135 PSI air compressor. That worked great, but I had to be really careful on the tooth edges.

Please put the information in the Format requested in the rules. ;)
