Pictured below is an otolith from an indeterminate cetacean, from the Miocene of the Calvert Cliffs Formation. I've had this particular specimen in my collection for some time, but was under the impression that otoliths weren't diagnostic to any degree, but my research surrounding cetacean dentition for a dolphin tooth I plan to purchase soon has proved otherwise, so I thought it would be worth putting it to the experts. Unfortunately I can't find my ruler to provide a sense of scale for the photos, but the specimen is approximately 4cm long and 1.5cm tall. Thanks in advance for any proposals as to the origin of the fossil Othniel

Yippee! The weather was nice enough today that I could finally go off for an extended ride on my bike. And of course I decided it would be best to make the hour's trip out to my favorite Miocene shark tooth site. So I packed my trusty Estwing hammer, a ziplock bag and my kneepads into the saddle bag. I even thought to take along my camera, so I can show a few pics. I however stupidly oversaw my water bottle which I had just put aside for a moment before I took off and didn't notice it until I got there, but my tongue didn't get all that dry and there was a nice little restaurant on the way home where I could wet my whistle. I spent about 2 1/2 hours chopping away at the outcrop and came up with a few nice ones. Here's what my dig looked like about halfway through. And here are a few in situ photos. There were a lot of uncomplete ones missing the roots or tips, so I just left a pile for the next group of locals that come along. I ended up packing 12 of them away and as is usually the case with shark teeth, I already had them all cleaned up just a half an hour after I arrived home. I decided to give most of them to my friend who lets me use his workshop and just hung onto the last 2 pictured below for the collection, since I already have a very good selection from this spot. The Carcharodon hastalis at the very bottom was one of the largest I've ever found there and despite the fact that it's missing the root and a bit of the tip, I got so excited when I found it that I forgot to take an in situ photo. Mitsukurina lineata Carcharias sp. Carcharias sp. Sparus aurata Carcharias (or Araloselachus, take your choice) cuspidata Carcharodon (or Cosmopolotidus, take your choice) hastalis

1 more from the same location, a vertebra. Photos 1 & 2 are the front and back, while 3 & 4 show top and bottom. One end appears flat, while the other is crudely pointed. Axis vert? I was thinking small mammal. Thoughts? thanks!

Libellula doris larva
Othniel C. Marsh posted a topic in Is It Real? How to Recognize Fossil Fabrications
Has this Libellula doris larva, from the Tortonian of Italy been painted on, heavily restored, or is it unrestored? Thanks in advance for any guidance Othniel

I found this concretion with something inside, looks like half of a nodule with something bone alike. Found it while sifting for Miocene shark teeth in a clay quarry in the Antwerp region in Belgium. I think the gravel i'm sifting is Pleistocene with reworked Miocene as i've found pieces of Mammoth bark in it as well. This piece leaves me clueless tho.. The concretion measures 9cm x 5cm sorry about the poor quality pics, that's the best i can get out of my smartphone... Thx!

Recently found this quite large and heavy (piece of) bone by the Schelde river shores in Antwerp, Belgium. Most pieces that wash up here are Mio/Pliocene but actually most Neogene layers are represented in the area as well as Pleistocene and more recent. I'm thinking whale because of the size, but honestly i don't have a clue. Measurements are 22cm x 10cm x 5cm thanks in advance! Dries

I participated in the Spring meeting of the Florida Paleontological Society this week end.. Saturday I was up at 5 am to drive to Gainesville and see some old friends including @digit. We had presentations from Paleontology students on their field projects and the treat of visiting the Paleontology research lab collections (Vert, Invert, Plants) under the guidance of UF experts. Dinner, discussion, and an auction in the evening . Saturday was jammed full. I have taken a set of photos which I'll share in another thread.. hopefully tomorrow. This is about Sunday. A field trip to Haile Quarry in Newberry, Fl. We are allowed in the Quarry for three hours and time flies when I am hunting fossils.. We moved twice looking in three sites.. I found many seashells and a few echinoids, including a gigantic one where I can not recall the name. I will likely get to a thread on my other finds Wednesday (Hunting again Tuesday). In this case, I wanted to show my prize and ask for Identification help before going to sleep. At the last site was a Sink hole, which had been partially excavated by a team of UF graduate students some decades ago, They found all sorts of bones, skeletons, teeth , Miocene aged. and I only had twenty five minutes before we left.. It was not sufficient to find a lot of quantity. but 10 minutes in, I found this Rhino upper Molar just laying on the ground. I had to pinch myself. I was NOT expecting Rhino. Note that Hunter_Schreger Bands are visible in the enamel, just as we would expect. So the 1st question is : Florida had 3-4 Rhino species. 1) Florida Rhino (Aphelops mutilus) From Alachua Co., Florida Lived ~8 million years ago 2) Panama Rhino (Floridaceras whitei) Adult (cast) and Juvenile From the Republic of Panama, Central America 3) Teleoceras proterum Lived ~10 million years ago 4) Menoceras ("Crescent Horns"[4]) is a genus of extinct, small rhinocerotids endemic to most of southern North America and ranged as far south as Panama during the early Miocene epoch. It lived from around 30.7—19.7 Ma, existing for approximately 11 million years. For the time being, I am thinking Teleoceras proterum, the one I know best. Here is an upper jaw of Teleoceras proterum. Teleoceras fossils have been found inside the Haile quarry. I have started at this photo above. It is not a perfect match, but I am thinking an upper left P3... Comments/Suggestions appreciated. Jack

Hey all, Looking for input from all the wonderful people I've called upon in the past! I found this tooth in 2022 sifting at GMR. Upon first glance I thought it to be a small dolphin tooth but after digging it out of my collection recently I put it under a higher power magnifier and actually looked at it with attention. I'm starting to believe this maybe a mammal tooth or canine specifically. I've been to GMR many times and have found a distal bone of a mammoth and a hoof bone of an ancient peccary which was identified by the curator of prehistoric animals at the Indianapolis State Museum. Any thoughts on this would be appreciated so I can try to file and put away for safe keeping! Thanks all! Steve

Two Cow Shark Symphyseal Teeth from the Virginia Miocene
shark57 posted a gallery image in Vertebrates
From the album: Fossils
Two Notorynchus symphyseal teeth from the Miocene Calvert Formation in central Virginia. Both have a funky center tooth and are about .65 inches wide. -
Hello, found this at Calvert Cliff about 6” long. Is this a croc jaw? If so, upper or lower? Thanks

From the album: Miocene fossils from Qatar
A calcite replaced miocene conus fossil I found. The rock itself was collected early last year but I cracked it open to look for echinoids. The calcite is paper thin and very fragile, and the inside of it is also filled with numerous crystals. Dam formation Abu samra member-

Hello Everyone, we are looking for help in identifying a fossilized tooth that was found in deposits dated back to the miocen-badenian age in Poland, Europe. That site is knows from Gigantopecten mussels fossils and Carcharias, Galeocerdo, Diplodus fish teeth but such tooth has never been found there before. Thank you for any identification ideas.

One beach hunt and two digs yielded four cow shark and a bunch of small teeth, some of which may have been in my last photo. The cow shark, my focus, are all new but frustrating; cannot say for sure if two really have non-serrated first points. Possibly broken? Too much cold water in the creek to hunt for a few more days.

This 4.5 inch meg was found at a land site in central Virginia along the contact of the Eastover and Calvert Formations. The colors make me think it is likely an Eastover tooth. -
Picked this up yesterday. It is easy to get excited on a small package. Looks like G. aduncus symphyseal but is much wider than the ones I see on a google search.

Spent about 2 hours surface collecting this morning, tides were not favorable but was still able to find some decent teeth including what I believe is either a partial dolphin or porpoise tooth. I thought that I had found a partial benedini, however it appears that it may just be a large partial curved mako tooth.

These are very common at an exposure of what I believe to be the Monterey formation (Miocene) in Santa Barbara county, California. They look quite different from most pectinid fossils I've seen in southern CA. Any ideas on ID, or references I should take a look at for this area? Thanks!

Got a surprise day off work on Tuesday so I decided to hit the cliffs to make the most of the day off. I got to the ramp around 10am to launch my kayak and headed to a beach I hadn’t been to in a little while. The trip started slow but I found a couple nice Hemipristis teeth to start getting my hopes up. I want finding to much in the wash and the water was to murky to find anything deep so I spent some time looking through debris around some fresh falls. Lo and behold a beautiful 1.75” Thecachampsa tooth is sitting right on top of one of the falls. It dried with some strange white staining that I wasn’t able to clean off, but none the less it’s still a great tooth. Continuing on I find a heartbreaking 2.3” megalodon that was broken almost in half (at least I got the larger half). Finishing up I got a few more nice Hemis and a handful of other nice smaller teeth. All in all in was a good day along the cliffs and it sure beat working. Thanks for reading, see y’all next time.

Recently, I found some mammal fossils right next to a river. The bones were buried in clay but the water had removed some sediment so they were visible although they were broken in tens of pieces. Later, I cleaned the soft clay from the bones and placed the small pieces together using normal glue because I have found out that its results are nearly as good as fossil glue or at least it doesn't have visible differences. Although the bones are almost complete, there is still a lot hardened red clay that doesn't go away with water or brushes. What should I use to clean the fossils completely without damaging them? (with household items if it's possible) Here's a photo of my 2 favourite ones.

On the last two trips my son and I have made down to one of our favorite spots near Saint Leonard, MD we found these specimens. I've some guesses about what they are but would appreciate some corroboration. All were found along the shore of the Chesapeake Bay in southern Maryland in the Choptank formation.
