This one doesn't disappoint! Beautiful, but it's not a terebratulid, they have loops to support the lophophore, not spiralia. I think this looks like an athyrid internal structure, so this might be Composita pikensis, methinks. 5 Life's Good! Tortoise Friend. Link to comment Share on other sites More sharing options...
FossilNerd Posted July 20, 2020 Share Posted July 20, 2020 I would suggest a Golden Drool Bucket award for @minnbuckeye, but I don't think it's fair to win one twice! (Just kidding! ) Great find Mike! It's a beauty. I wouldn't count everyone else out yet! We have some great stuff this month from verts, jaws, and teeth, to preserved internal brachiopd structures. Which I very much like @Jackson g! 1 The good thing about science is that it's true whether or not you believe in it. -Neil deGrasse Tyson Everyone you will ever meet knows something you don't. -Bill Nye (The Science Guy) Link to comment Share on other sites More sharing options...

Any chance you have any brachiopod internal anatomy references you could share or literature(If so just shoot me a pm)? None of the pdfs I have on Mississippian fauna include interal preservations, just outside anatomy (ventral, dorsal, lateral, & anterior views). I asked my go to professor, and he had nothing of the sort. Being an internal mold doesn't help much when wanting to be precise! 1 Link to comment Share on other sites More sharing options...

Internal molds and preserved structure can, in many cases, be better than external features in brachiopod id. Will chat in PM, i have some useful papers. 1 Life's Good! Tortoise Friend.

Nautiloid Posted July 24, 2020 Share Posted July 24, 2020 Here’s my first entry into this month’s contest. It is a phyllocarid with both valves and an almost complete telson. (The telson is on the underside and one of the valves is squashed underneath the other). Both the telson and the valves have great detail. It was found by me last Saturday. I’ll be hopefully entering an even nicer fossil later this month. Just gotta finish up the prep.

Nautiloid Posted July 24, 2020 Share Posted July 24, 2020 Actually, I might just do the one this month. Not sure I’m gonna finish the prep before August. Especially since I’m going away all of next week. I’ll see though. I’m pretty close and if I can get it done in the next few days I’ll still enter it. If, not I’ll enter it next month.

The heading for my entry is: "Simplify your fossils " Name: Hippurites nabresinensis Futterer, 1893 (Hippuritid rudist) Formation: St. Bartholomä-formation, Gosau-group (Campanian) Site: St. Bartholomä, Styria, Austria (Creek between Kalchberg and Kreuzegg) Found: 07/05/2020 This two polished transverse sections are about 3 mm away from each other and the specimen consists of two concentric "circles" (outer shell and thin inner shell) with two bulges (the pillars). The former void is filled with light orange, spary calcite. Left section is apical view, right section is adapical view. The left section was impregnated with paraffin to mask the many hairline cracks, so the two look a little bit different. Franz Bernhard 7 Link to comment Share on other sites More sharing options...
Quer Posted July 25, 2020 Share Posted July 25, 2020 There goes my first participation in this contest: Date of discovery: 17/07/2020 Almucidaris falgarsensis (Lambert, 1933) Terradets Formation (Upper Campanian) Barcelona, Spain (SE Pyrenees) Almucidaris is a very uncommon cidarian genus, due to its plates enlarged to form marsupia for breeding. North-American paleontologists Blake and Zinsmeister created it in 1991 and described Almucidaris durhami as the type species, from a specimen found in the Antartic. Till now, only this two species have been found showing this characteristic. This specimen is the best preserved I know pictured, especially its apical disc.

Captcrunch227 Posted July 27, 2020 Share Posted July 27, 2020 After several consecutive hunts that had turned out to be busts, I persevered and went to same creek again. After spending a good hour and a half finding nothing but mosquitoes, my eyes fell upon a most wondrous sight. An extremely rare and gorgeous Pliosaur tooth with the partial root!!!! I reached out to my paleontologist friend and he concluded that this tooth most likely belongs to Megacephalosaurus eulerti. These are extraordinarily rare here in North Texas (and in the states in general). I only know of less than a handful that have been found here in the last decade.

Captcrunch227 Posted July 27, 2020 Share Posted July 27, 2020 I spent Saturday morning in the company of a good friend outdoors looking for fossils. Beating the sun up out of bed, we headed to explore a new creek. We found broken septarian nodules EVERYWHERE and the odd shark tooth here and there. After an hour of finding zilch, I spotted what appeared to be the one millionth broken nodule. But this one looked different. I walked up to it and started to piece together what it could be. I told my friend, “There is no way this is what I think it is.” What are the odds right? “YES IT IS!” he replied. I pulled out a stunning set of associated vertebrae belonging to Xiphactinus audax. 2 full verts with processes, half of a third vertebrae and a tiny piece of a fourth vertebrae. And to make it even better, it’s resting in a flat piece of matrix that acts as a perfect display base.

So, I might as well throw one into the ring in hope other entries do not show up, or at least for the invertebrate category!! Then I may have a chance at victory. LOL My find was on 6/15/2020. As can be seen, prep was necessary to bring out the trilobite's detail.Prep was finished on 7/10/2020. I do have to give @RandyBpartial credit for talking me into showing him this site. And I must heavily credit @isotelus for the wonderful prep! The trilobite is 1.75 inches long. This is Thaleops ovatum Platteville Formation Ordovician Grant County, Wisconsin Great specimen!

The Mushroom Whisperer Posted July 28, 2020 Share Posted July 28, 2020 Florissantia sp. cf. F. quilchenensis Naches Formation, Central Washington State, USA Late Eocene and Oligocene. July 04, 2020 2 of 6 flowers found in the Naches Formation. I'm currently unable to find record of any other Florissantia sp. finds in this formation. One flower is compressed transversely (L), and one is compressed laterally (R). Photos were taken with two different cameras, in natural lighting, LED lighting, and shade. 9 Link to comment Share on other sites More sharing options...
