Franz Bernhard A brachidium, (plural brachidia) is the term for one of the calcified lophophore support structures in brachiopods in general. (some don't have support structures) A spiralium, (plural spiralia) is a particular type of brachidium that is spiralled and occurs only in certain groups of brachiopods such as the orders Spiriferida, Spiriferinida, Athyridida and Atrypida, all now sadly extinct. 6 Life's Good!

The Amateur Paleontologist Posted March 22, 2020 Share Posted March 22, 2020 @Rfossile My reactions to seeing your pycnodont fossil - (before prep): oh that's a sweet jaw, I like it (after prep): what the heck that's absolutely amazing!!

Miocene_Mason Posted March 22, 2020 Share Posted March 22, 2020 (edited) Hello everyone! Happy to be able to actually put in some eye candy this month: a croc vert!@Gizmo was kind enough to take me on a wee fossil hunt after an excavation. Though the area we looked through had been thoroughly picked through the day before, someone left this rarity on a boulder for me to find. And that is why you do your homework!

Pterygotus Posted March 23, 2020 Share Posted March 23, 2020 I came across this tooth while processing some matrix. All I could see was this tiny shark tooth on the outside and this black bit on top so I wacked it and this beauty came out! What I originally thought was a tiny sharks tooth turned out to be part of a massive one. I think I found the edge of the tooth while sieving the matrix but dismissed it as nothing . It is the biggest striated hybodont tooth I’ve ever found and I think the preservation’s pretty neat! It measures 19 by 12mm. Date of find: matrix collected 21st March 2020, tooth found 22nd March 2020 Name: hybodont shark tooth cf. hybodus or planohybodus Age and formation: Bathonian, Jurassic, Forest Marble Formation Found: Watton Cliff, Dorset, England 14 Link to comment Share on other sites More sharing options...

DPS Ammonite Posted March 23, 2020 Share Posted March 23, 2020 Here is a silicified Pennsylvanian sponge from the Naco Formation of north central Arizona found north of Payson. This sponge is probably a new species and awaits an expert to help describe it along with several other Arizona sponges that I have found. The sponge which sort of has the texture of a sourdough roll with lots of air bubbles has a series of roughly 1 cm long almond shaped holes that are radially arranged around the assumed center of the sponge. Detailed photo is 2.2 cm across. Photo of whole sponge is about 7 cm by 7 cm. Date of Discovery: March 9, 2020. Common Name: sponge. Scientific Name: Phylum Porifera, Class unknown. Found in the Pennsylvanian Naco Formation. Found north of Payson, Arizona, USA. 14 My goal is to leave no stone or fossil unturned.

Troodon Posted March 23, 2020 Share Posted March 23, 2020 I finally received notification from my Prep person that one of the jaws I found in my fall trip was completed. The photos are from that individual, will pick it up when I eventually get out in to dig this summer . The preservation was not the best but jaws from very young individuals are extremely rare so I wanted a professional to preserve it and I allowed some restoration. Family: Hadrosauridae Genus/Species: Edmontosaurus annectens Juvenile Right Dentary : 30 cm long Discovery date: Sept 19, 2019 Prep completion: March 17, 2020 Formation: Hell Creek Location: Harding County, South Dakota Age: Cretaceous, Maastrichtian Dig site 24 Link to comment Share on other sites More sharing options...

caldigger Posted March 24, 2020 Share Posted March 24, 2020 I told somebody recently that this might be a good time to enter the FOTM competition since it seems half the world is going into lockdown mode. But there have been some great entries as of late that makes that statement no longer valid. Lots of competitive stuff this month and it's not over yet! 2 Link to comment Share on other sites More sharing options...
