North Carolina Cretaceous angel shark cartilage/vert., fish skull cap, mosasaur tooth, and more!
fossil_lover_2277 posted a topic in Fossil Hunting Trips
Collected these in North Carolina this weekend. Angel shark vertebra w/ fossilized cartilage, fish skull cap, mosasaur tooth, soft shell turtle fragment, worn Otodus tooth, goblin shark teeth, crow shark tooth, bull shark tooth, and not sure what the smallest shark tooth is. These come from a mix of Cretaceous Tarheel and PeeDee formations and Pliocene Yorktown formation.

Plesiosaur or Myliobatis ray vertebra from Cretaceous of North Carolina
fossil_lover_2277 posted a topic in Fossil ID
Anyone know what type of vertebra this is? Found in North Carolina, could be from either Cretaceous Black Creek group. 2.5 cm from left side to right. Could it be a plesiosaur cervical vertebra? Or is it Brachyrhizodus spp., a Myliobatis ray? I already have one Brachyrhizodus spp. vertebra and it doesn’t look like this, but maybe this is a different part or the backbone. Just based on size I’m leaning towards Brachyrhizodus, but it looks almost identical to a plesiosaur vertebra. Oooo

Two oddities here, both from Yorktown spoils. The first has a general tooth shape with a double root, but is uniformly coated with a smooth enamel. The broken roots show cores similar to other marine mammal teeth I’ve found. Maybe this is unerupted? The second looks like an osteosed fish skull element but is just huge for the location at 95mm. The porgy occipital elements I’ve found here are barely 15mm long. any direction is welcomed! frank

Greetings again Thisis a second vertebra also found at the Lee Creek Mine (aka Aurora) in Yorktown spoils. It is 50mm in length, rather porous and very light. I was thinking bird, but thought I'd get some other opinions. Any ID suggestions? The photos in order are: "bottom", "top", "side", end 1 and end 2

Greetings, Since There's not much collecting to be done here, I've started diving into the collection and trying to ID and label. I found this vertebra at the Lee Creek Mine (aka Aurora) in Yorktown spoils. It is 33mm in length, rather porous and very light. I was thinking bird, but thought I'd get some other opinions. Any ID suggestions? The photos in order are: "bottom", "top", "side", end 1 and end 2

I thought I had seen the whole gamut of shapes and materials from the Lee Creek mine spoils, but this tiny (2cm) specimen has me stumped. It looks like a tiny brain with “folds” radiating away from a central seam. The “bottom” has a deeper seam, like the meeting of two halves of a walnut. I have found blocks of milky amber in North Carolina before, but nothing with any symmetry. if it’s a coprolite, what’s the seam? Could it be a little skull cast? I have been staring at this thing for a year. Please help. Frank

I only try to post real mysteries and this is a specimen that is unlike anything I’ve found from Yorktown in that it is exceptionally dense. It has a fin shape and could almost be the dorsal process of a vertebrae except that the striated pattern across the face of it doesn’t look familiar to me as such. Feels like fish material? When it’s wet, the color is bright orange, almost like enamel. I don’t know, it’s just… weird. Thought I’d bring it before the court. Thanks!
-
I found this in the Aurora Fossil Museum dig pits, so it’s likely Pungo River formation (Miocene), although there’s a chance it could be Yorktown formation (Pliocene). Any idea what it is? My best guess is some sort of jaw bone, maybe from a fish.

Hi all, I found this turtle peripheral in eastern North Carolina. I believe it is from Cretaceous Black Creek group sediments, but Pliocene Yorktown formation is also possible (both are marine). A person I showed it to said it was a Hesperotestudo (tortoise) peripheral, not sea turtle, so thus terrestrial (I guess it might be terrestrial Pleistocene, but that would be unlikely, I don’t find much of any Pleistocene material where the shell was found). However, it actually looks similar to a peripheral I have from a known fossil sea turtle. Is this peripheral sea turtle or tortoise?

Decided to head to a stream with my kayak on my day off recently. I frequently go to this site because it is not too far of a drive. This site gets collected a lot but it looked like no one had been there in a while. Without people walking over the site, small fossils start to be exposed. I crawled around for a couple hours and found many small fish bones and otoliths. Here are some photos. Lots of inarticulate brachiopods. Only two species found here. The round Discinisca and the lingulid Glottidia which is always broken. There is a Lepophidium (Cusk Eel) otolith above the Discinisca

I found this tooth in Greens Mill Run in Greenville, NC. I’m leaning towards croc due to the size of the dental cavity relative to the size of the tooth, but perhaps it is a mosasaur. It has one carina on the anterior side of the tooth, none on the posterior side. Also, if it is croc, is there a way to identify whether it’s Cretaceous or Pliocene? Or if either croc or mosasaur, perhaps genus ID? Thanks!!!

A while back I collected several pieces of sizeable whale bone from Greens Mill Run and was able to ID them as to specific skeletal element (several were ribs, verts, mandibles, etc.). However, this one piece is fairly sizeable and has a distinct shape (it is worn down some), pretty sure it’s part of a skull, but can’t figure it out. Any whale experts out there think they might can help? It’s from the Yorktown formation, and even though Greens Mill Run cuts through other formations, this one came from a section of the creek with Pliocene exposures and the other whale bones I was able to ID, so pretty sure it’s a Pliocene baleen whale.

Soooo a few days ago new material was dumped at the Aurora Fossil Museum. Well, I made the trip there before the Saturday crowds, and was well rewarded!!! These were the best finds of the day =p btw the stuff underneath the shark verts are 2 stingray spines, a filefish vert, a burrfish bone, a beat up dolphin jaw bone, and what I think is some type of fish skull cap

Greens Mill Run finds, including baleen whale fossils
fossil_lover_2277 posted a topic in Fossil Hunting Trips
Made a recent trip to Greens Mill Run and got quite a few nice fossils, particularly fossil bone. Large fragment of a Pliocene baleen whale lower jaw bone, whale rib fragment, baleen whale tympanic bullas, unfused whale vertebral epiphysis, Chesapectens jeffersonius, other Chesapectens spp., clams, etc. All collected in-situ, all from the Yorktown formation. Also quite a few sharks teeth collected from gravel bars. Also one pic, the one with the belemnites lined across the top, is all in-situ Cretaceous stuff. Great trip, digging the stuff up was a nice change from all the gravel sifting haha

Hello, I am curious about this piece of what i think may be a jaw fragment. Found on James River in Virginia within Yorktown Formation. There appears to be one intact tooth and a portion of an adjacent tooth that has broken, leaving a cavity. Measures approx 2 x 1.5 x 1 cm. (The background grid is in centimeters) Appreciate any/all feedback. Thanks!!

Bone fragment found on the York River in Virginia. It is the Yorktown Formation, Pliocene epoch. I'm wondering if it is a vertebrae fragment, and what species it might belong to. It's convex on one side, and concave on the other.

Found this odd 9" long jaw-like fossilized bone in a small creek within the Yorktown formation in Virginia between the York River and I-64. It is atypical of the Baleen Whale and Ice Age mammal bones I have found in the same area. Any help with identifying this specimen would be appreciated.

ID requested: Miocene (micro) sharkteeth from Lee Creek Mine (USA)
ziggycardon posted a topic in Fossil ID
Hi everyone! Little over a week ago I recieved some new bags of microfossil matrix and this time there was a bag with material from the Lee Creek Mine, Yorktown Formation, Aurora, North Carolina, USA (Miocene, 14,5 mya) This material is quite rich in shark teeth as I found little over 90 shark teeth in it. I have photographed a couple of them already and posted them in my microfossil topic. But since I doubt I will get many help with the identification of the teeth there I am going to repost the first batch of teeth here (I apologize for the repost admins) and upload the rest of my finds from that material in this topic from now on. I have tried to ID some of the teeth with the help of the website Elasmo & the paper "Geology and Paleontology of the Lee Creek Mine, North Carolina, III by Clayton E. Ray and David J. Bohaska", but I feel like my eyes aren't enough trained yet to distinguish enough to make proper ID's on all of the finds, so I not all ID's will be a 100 % correct I am affraid. Here are some of the first teeth I photographed. I would be gratefull if some of you could help my ID some of the teeth of verify /correct some of the ID's I have come up with. If the photo's aren't clear of good enough, just let me know and I'll try to make some more/better ones. Thank you in advance! The first tooth which is by far also the favorite in the bunch: Tooth 1: a Sphyrna zygaena tooth? Tooth 2: a chunk of Galeocerdo sp. tooth Tooth 3: another Galeocerdo sp. tooth Tooth 4: This one is a tooth which I have a hard time identifying as I feel it has a lot of features that return in different teeth. Physogaleus? Sphyrna? Loxodon? Tooth 5: another I haven't managed to ID yet. Tooth 6: Carcharhinus sp. Tooth 7: could this be Negaprion sp.? Tooth 8: Tooth 9: Scyliorhinus sp.? Tooth 10: Megachasma sp.? Tooth 11: Megachasma sp.?.jpg.07507fea64bddeeb831b2fd240c955b9.jpg)

Found this in the Yorktown formation in Virginia. Not sure which bone this is from a Baleen Whale. Any ideas?

I found this shard of bone on the York River in the Yorktown formation, and the pattern on one side is curious. I’m wondering if anyone has seen this, or if it’s a diagnostic texture? Thanks for any help!
