I posted in a trip report a few weeks ago that one of my boys found two big fragments--including the joint--of whale jaw in a cliff fall from Calvert cliffs. The assumption of jaw was based on what seemed like a good comparison to a jaw on fossilguy.com plus overall shape. But a commenter suggests that the joint is maybe not flat enough to be from a mandible and that this could really be a rib. So I'm looking for any second opinions. We would really like to get a proper ID, especially as my son wants to fill in the missing segment and make a single piece out of the two pieces for display. Because of the way they came out of the fall, although they were with each other, we aren't 100% sure of what the orientation of the two pieces ought to be with respect to one another. I have put the two pieces in a few different configurations just to show what each might look like. Having a proper ID would really help. Any whale experts, please have a look and let me know what you think.

Hey everyone! I've been offline for a very long time (too long ), but I'm finally back in the fossil game! I celebrated the start of the summer vacation the right way with quite a few hunts in Antwerp, and those hunts didn't disappoint When in Antwerp I especially look for shark teeth, but we find other stuff as well (bones and teeth of mammals), which I might make another post about We've also been on a mini vacation to the Belgian Ardennes so stay tuned for more photo spam One of the first finds was this beautiful C. hastalis (bonus points if you spot the matching nail polish ) A pic of how we find them around here Had a lucky day when we found this P. benedeni! Another lucky day when we found this beautiful hastalis And another VERY lucky day when found this beast of a C. carcharias This is the first we've found in all those years of searching for shark teeth!! (they're very rare here in Antwerp) We just couldn't believe our luck with this one Can't wait to explore this location further the coming weeks I hoped you enjoyed this summary of our hunts! Of course we find more teeth than just the 'picture perfect' ones, but these are definitely the highlights Kind regards, Angie

I found this the other day in a bag of Aurora micro matrix. It's only about 3 mm long. Could be Miocene, Pliocene or Pleistocene as all three run through the mine and the matrix is thoroughly sifted together during mining operations. There appears to be a root and possibly two tips broken off?

Hi. Does anyone know the identifications for these whale teeth? Thanks for your help. This tooth was found on the Ernst ranch in Bakersfield, California. It is from the Miocene-aged Temblor formation. This tooth was found by a diver near Savannah, Georgia. I unfortunately don't have any more information on it.
-
I am pretty sure this is a complete tooth. I’ve never found one with this pattern.
-
These bones were found a few feet apart from each other falling out of an eroding bank.

Here are two vertebrae that I've found at Calvert Cliffs sites (Miocene exposures) in Maryland in recent weeks. The first I also included in a recent trip report, but am posting it separately here along with some better pictures. Any idea what kind of animal this came from? My first thought was a cetacean/dolphin based on the oval part of the photo in the upper right (which looks sort of like the epiphysis attachment point--though that's probably not the correct term--on another but otherwise different looking cetacean/dolphin vert I found). However, I haven't yet found pictures of any similar verts to this one online. The second vert below I found a few weeks back. I think it may be from a fish but would appreciate confirmation or correction of that. I had trouble getting clear photos of the top (looking down at the "ears") and bottom, but can try again if needed/helpful. It doesn't look to me like there are broken processes on the bottom side but I could be wrong. Thanks for any help with these!

Hi everyone. I found this fossil while combing a fossil beach on the Chesapeake Bay in Virginia. The beach is littered with fossils from the Miocene including Chesapecten jeffersonius, Ecphora gardnerae, bone fragments of all sizes, and the occasional shark tooth. This stood out to me as being an unusual bone fragment so I picked it up. It is about 3 inches or 7.62cm in length. Is this a piece of a bone or something else entirely?

I celebrated my birthday recently with three days of shark tooth hunting along Maryland's Calvert Cliffs (Miocene exposures) and had a blast, despite the hot and muggy weather. I still haven’t found that elusive Meg, but I added some great new finds to my growing (since January) collection! Day 1: Matoaka For the first day, I went to Matoaka. Low tide was in the early morning and I wanted to beat both the heat (as much as possible) and crowds, so I got up bright and early, arriving just after sunrise. I’m pretty sure I was the first one on the beach as I didn’t see any footprints in the sand and didn’t see anyone else until I doubled back later in the day. I didn’t find any particularly large teeth but I did find several firsts: my first “cookie” (cetacean epiphysis); first barracuda tooth; first thresher shark (Alopias sp.) tooth, I think; and first Miocene croc tooth (a bit worse for wear). I also found a root worn Carchardon hastalis (above on the far right) and a few dozen other teeth (Hemipristis serra, Physogaleus contortus, Galeocerdo aduncus, Carcharhinus sp., and Negaprion eurybathrodono) in various conditions, shown below.

Hi Everyone! I just started fossil hunting on the Chesapeake Bay in Virginia a year ago and am hooked! What a fun way to get out on the water and spend a few hours. I have found all sorts of stuff so far and am anxious to get back out for the next hunt. I joined The Fossil Forum because I am eager to learn, share my finds, and get some ID's on unknowns in my collection. I am excited to be a part of this community. I hope everyone is doing well. Warm Regards, etj915

Whenever I am hunting , I tend to consider everything a fossil. So when you are with me, I am constantly coming over asking "Is this a rock?" or Do you think it is coprolite? Is that enamel? and I know a LOT about Florida fossil shapes. So right after, a companion said that this was a rock, I picked up something that might be a rock concretion. However, once again I am skeptical and will ask @Boesse to help me differentiate marine mammal from rock. So other TFF members can chime in with opinions. Rock or fossil? It is a littleover 2 inches in length

Hello, I found this old jaw while the lake was down in Travis county, Texas. I thought it resembled an older species than Equus. Thanks

This is a strange one. Tooth or denticle or? @Al Dente @MarcoSr

I know bone fragment ID's are usually left at just that "bone fragments," but I've seen some pretty amazing ID's here lately and this is my favorite little puzzle. It was found on Edisto beach which harbors Pleistocene mammals mixed with Miocene and Holocene aquatic creatures. More info on the location (including a list of mammals) can be found here: https://markgelbart.wordpress.com/2010/05/25/the-edisto-beach-fossil-site/ It's completely hollow and has what appears to be healed over bite marks. Even if it can't be ID'd, if anyone can confirm or deny if the markings are really bite marks I'd be over the moon. Furthermore, the bottom is concave. I have a photo of the bottom too if you need it, but I ran out of room for this post

This came from a bag of mixed micro matrix from the Lee Creek AKA Aurora Mine which was sifted, sifted again and sifted some more. It is a mixture of material from three formations: the Miocene Pungo River Fm., the Pliocene Chowan River Fm., and the Pleistocene James City Fm. After digging through reputable resources covering the area from Maryland down to Florida, the administrators and I have mostly ruled out Miocene as none of the references mention anything similar from that time period. Three names are given for the species from the Pliocene and Pleistocene. Ward and Blackwelder (1987) identify Arene pergemma, with a description and illustration that looks very much like this gastropod and is about the same size, from the Lee Creek Mine1. The Paleobiology Database says that Arene pergemma is an old name and gives Marevalvata tricarinata as the accepted name2. The Neogene Atlas of Ancient Life says that Marevalvata tricarinata is no longer valid either, and has this species recombined as Arene tricarinata3, a name which actually predates Arene pergemma4. The Neogene Atlas does list a very similar shell, Arene agenea, which lived during the early Miocene. However, A. agenea has a circular aperture while the mystery shell has a more elliptical aperture from every angle I use th photograph it. A. agenea also has less defined ornamentation than the shell in question. Furthermore, the Neogene Atlas only lists A. agenea as occurring in the Chipola Fm. of northern Florida4. All agree that the fossil occurs only in the Pliocene and early Pleistocene from North Carolina down to Florida, but only mention them occurring in North Carolina in the Pleistocene Waccamaw Fm. further south and the Late Pliocene Duplin Fm. to the west. Ward and Blackwelder discuss a couple similar species in their discussion of the genus, but give no identification for them in the book I have available. Given this, I think this specimen is most likely from the Pliocene. However, after deliberating with a TFF malacologist, this might be a new undocumented species altogether that could be from any one of the three time periods and formations.

Hi everyone, this believed to be "tooth/bone" was found in the Dorchester Creek / Ridgeville area.
-
Hi everyone, need help with some identification here. The first photos of the brown looking tooth was found in Edisto, while the bone you see was found in Dorchester Creek in Summerville.

I biked off to my favorite Miocene shark tooth site again this afternoon and when I got there there was already a family with 2 young children scratching and sieving away at it. A bit of conversation showed that they were pretty new to it, so I gave them a few tips and gave the kids all the small Carcharias ones I was finding. Eventually they said goodbye and trundled off down the path. It wasn't even a minute after they were gone that I suddenly found a good sized Galeocerdo aduncus, my largest one to date. A couple of pieces were broken off the edges, but I managed to find both of them in the sand and could glue them back on once I got home. Shortly after that, a Hemipristis serra anterior popped out, also in 2 pieces which I could also repair in the end. That was only the second one of this species which I have found there up to now. Needless to say, I was pretty happy to have found them both, despite having to glue them back together. There were also a nice little Carcarhinus priscus and a Carcharias acutissima to top things off. Here they are.

Found both of these teeth today while out on the Chesapeake Bay. Would’ve come from the Calvert formation. I’m believe the second tooth is a chunk of a small megalodon based on the serrations and root of it, first tooth I am not sure on. Both teeth are approximately 2 1/3 cm. Thank you!

Good evening everyone, I recently did some fossil hunting in the Green Mill Run river in Greenville, NC. The water was pretty low - ankle/shin deep most of the time. I'm pretty new to fossil identification so figured you guys could help me out. Location: Green Mill Run, NC Date: July 2020 Excavation process: Shovel to river bed The first looks like a jaw with teeth indentations. It's about 1.9" (50mm) with brownish coloration. Additional photos below.

A couple days ago I spent the day at the Gay Head Cliffs at Martha’s Vineyard. This beach is famous for its vibrantly colored clay cliffs. I did not fossil hunt in the cliffs themselves because as far as I’m concerned it’s a federal offense to even touch the cliffs, but I did find a couple of clams lying along the surf that had eroded out of the cliffs. They’re pretty neat because they’re the first Miocene fossils I’ve ever found. I was hoping to find shark teeth because I had heard they could be found there but at least I found some fossils.

Show Us Your Wide Boys! A Thread For The Widest And Fattest Megalodon Teeth
Kurufossils posted a topic in Member Collections
Heres a fun thread for those to show off their widest and fattest looking megalodon teeth fossils in thier collections. I'll set the tone with the widest fat boy in my collection, I don't have digital calipers but it measure roughly 5.4 inches wide by 6.1 inches long. When I close my hand together it looks even more monstrous. Share yours and join the wide boyclub Got the idea while thinking about what the widest megalodon tooth ever found measures, if anyone does know do share in this thread!

My boys found this the other day. It does not look like a whale or porpoise vert, I don't think. Before posting a trip report, I was hoping someone could tell me what it is.

Some of the awesome finds from 2 days worth of hunts at Matoaka Beach. I have no clue what the vertebrae belonged to (I know it’s not a shark). I believe the large bone in the back is whale, just don’t know what part. Lastly, if anyone has any information on what the shark teeth are exactly please let me know. I believe the big one is a mako, the long pointed one may be a lemon, and of course the snag for tooth. If I am incorrect please let me know! Looking forward to going back and finding more!
