    Calvert Cliffs, MD, USA

    Hi all! I hope you are well! I recently made my annual trip to the Washington, D.C. area, which always includes a trip to the Miocene deposits of the Calvert Cliffs. I think I have a general idea on these IDs but wanted to confirm with others, especially the first two sets of images. I’ve tried to group like fossils as well. Thanks for looking! 1 (ray dermal plate?): 2,3, and 4 (otoliths?): 5, 6, and 7 (with 6 and 7 magnified at the end, respectively; cetacean ribs?): 8 (crab claw?): 9 (ray mouth plate part?): 10 (?): 11 (third image is root zoomed in; cetacean tooth?): Plus, here are a couple of finds that I just wanted to share for fun! Thank you again!

    Cetacean bone

    Hi folks. I found this very dense bone today. It was already weathered out of the Siltstone. It’s 16cm or 6 inches long most likely late Pliocene I think definitely cetacean and wondered about premaxilla. “Top” oyster shell attached top of picture remains of barnacles visible in other photos. ends. Note the canals. Couple of oblique views to show surface texture such as longitudinal grooves thanks for looking.

    Andalusia, AL vertebrae

    Hi all! I made a journey down to Point A Dam today (despite high river levels) just to shuffle about. I came across these two vertebra, the smallest of which is clearly a fish, but I’m not quite sure what the other is. Cetacean? If you have any info on either, please share. Thank you! P.S. I somehow never have a ruler with me so I used the lines of a college ruled notebook, which are separated by 7.1 mm, as a makeshift scale. I apologize for this. 1: 2:

    Cetacean Otolith

    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

    Dolphin Tooth

    Below is a dolphin tooth being sold as that of a Goniodelphis hudsoni, from the Peace River Formation in Florida. The tooth does not look like that of a Goniodelphis, however, as they appear to much more rounded. I personally suspect it's from Delphinodon, given that I have seen some similar teeth identified as such on other ID threads on the forum, but I can't say for sure. I must once again call upon your wisdom, @Shellseeker, and I believe @Boesse is also something of a cetacean expert. I'm yet to purchase the tooth, so I haven't got many pictures at my disposal. Thanks in advance for any guidance Othniel

    Florida Cetacean Vertebra Fragment?

    Hi All, I found this chunk of fossilized bone on the beach in Tampa Bay, Florida, USA. It's approximately 2" x 1" and appears to be broken off on both ends. It has distinct features, like a straight spine down the middle that tapers on one end and divides or forks into two bones on the other end. My only guess is a part of a Marine mammal Vertebra? All IDs are appreciated. Thanks Lynn

    Bone? Pseudofossil?

    Wondering if this is a piece of bone, just a pseudo, or something else? Found in the vicinity of Santa Barbara or Ventura county in California. Thanks! IMG_5378.HEIC
  11. I have acquired some whale fossils and the best ID offered by the seller was "whale". Is it possible to get an ID to a genus level on fossils like these? I have a couple more bulla and one more tooth but for now, to keep things simple I'll post pics of one of each. I don't have find location info, definitely from the USA and filling in the blanks from the seller, I'd say it's likely they were found on the lower east coast somewhere.
  12. I had been itching hard to be on the beach, so I slipped away to the bay Saturday and Sunday after Thanksgiving to find some fossils along the Calvert cliffs. I really want to beat my personal best megalodon tooth from Calvert which measures at 4” on the dot; I know that will be difficult so I’m really trying to go more often. (Spoiler: I don’t find my record breaker) Day 1: I really didn’t have time to go out on Saturday but I figured I could delay my responsibilities for a little and fight the wind to spend at max two hours on the beach. I arrived on the beach about 20min before sunrise and started searching with my flashlight and quickly found a nice little megalodon, a little beat up but hey, a meg is a meg. I continued on and found a heart breaker cetacean tooth, the crown much larger than most cetacean teeth I find here, but alas the crown was missing a chunk and the root spit in half and hollow. Before starting my walk back I found a handful of usual teeth from this beach, a few hemipristis and physogaleus and a thumb nail size posterior meg. As I get back to the beginning stretch of beach that I first searched with my flashlight, I found a beautiful epiphysis disk with a 1.8” diameter sitting right next to a 1.9” megalodon . Leaving the beach just over two hours of walking I got a surprising haul, definitely worth the trip. Day 2: I had more time to hit the beach on Sunday, so accompanied with my girlfriend we launched our kayaks for sunrise then landed to begin our search. Same as the day prior the waves were hitting the beach rapidly and the water was murky making it pretty impossible to search beneath the water, so most of our finds were right at the edge of the shell line or high up on the beach. We started by each finding a few large hemipristis teeth all measuring around 1.4” and a couple nice hastalis. My girlfriend found her second megalodon tooth measuring 1.5”, it was a bit beat up but for her second meg she was thrilled. I don’t often go out back to back and I remember why, I’m exhausted. None the less I’d do it again in a heartbeat if I got the time and the weather and tides want to cooperate. It was a great two trips even though I didn’t break my record, but that day will come! Thanks for reading y’all!

    Cetacean bone fossil ?

    Found this on a beach near Santa Barbara California, hard rock, semi porous in some areas. Was wondering if anyone recognizes the shape and what it could possibly be. A lot of fossil whale bone has been found in the area. thank you.

    Occipital condyle?

    I don't know bones very well yet, but my guess on this one is part of a cetacean occipital condyle. Found in Summerville, SC, in a creek where I find cetacean verts and small cetacean teeth (as well as shark teeth, etc.). Oligocene through Pleistocene layers are present, but there seems to be more Oligocene than anything else. Longest part is 4.25 inches. Any thoughts? Thank you!
  15. Hello and thanks for allowing me to become a member. I live in Costa Rica so things commonly available in the US and Canada can be really hard to find here, so I am asking people to consider this when responding. I purchased several whale vertebrae from a local who found them on the beach which I plan on cleaning and mounting as art objects. I have a woodworking shop here in CR so I have the tools at my disposal to properly mount these amazing pieces. I'm looking for advice on how to clean and get the smell out of these bones...believe me, they are RIPE. You can smell them from 6-8 feet away. My thought was to bag them and wrap the bag loosely with tape to save on the volume of whatever chemical treatment I need to use to accomplish this, but as a complete beginner, obviously I am open to suggestions from those with experience. Thanks.

    Fish and cetacean jaws for ID

    I found two fossilized jaw segments yesterday that I need help IDing, please. I believe the first is either barracuda or wahoo, but I've done a little research and am still not sure how to tell them apart. My guess is wahoo, based on the tooth thickness increasing as it gets closer to the root, but some descriptions I've seen of wahoo teeth describe them as "needle-like", which these are not. Jaw section is 50mm long. Tooth goes from about 1 mm thick at the point to about 5mm at the base. Found in an area that is heavily Oligocene but with a small amount of Miocene (coming from an overlying Pleistocene lag deposit). Jaw #2 I believe is cetacean... something like an echoventator. I previously found a similar one in the same creek, but the spacing between those teeth were greater (both have the double-root teeth). This creek is also Oligocene with some Miocene from overlying lag deposits. 62mm long and 32mm tall. Wet to show the double-root tooth sockets better: New jaw on left, other from same location on right: I hate to @ people if I don't have to but, from reading old posts, I think @Al Dente and @MarcoSr can probably ID wahoo vs. barracuda. Thanks so much!

    Oligocene of Washington

    Another productive day hunting early Oligocene marine deposits of the Lincoln Creek Formation in Washington state, US. with James Goedert and Cheng Hsiu Tsai. Overcast day with showers, rare for a summer day here. I was finding mostly glendonite when I spotted a nodule that's a bit more rare than the overcast day we were experiencing: a tympanic bulla of an early cetacean. Donated to Tsai of the National Taiwan University for study.
  18. Hi all. Dropping some photos here. Believe one of the bones could be a carpal of a baleen whale? Not exactly great with anatomy. Would type more at length, but recently broke MY fifth metacarpal playing with my daughter and typing is not so fluid. The finds are from the San Diego formation. Pliocene era - very rich. Will post some other finds of manatee bone and great white teeth later when I can dig out. Also have some Eocene mollusk finds. I grew up mineral and fossil hunting as a youth with my parents and family friends. I revived the interest over the past 8 years and recently moved back to SD from Oregon where I really had no time to hunt. My academic background is in biology (B.S) and pharmacology - where I recently earned my PhD in toxicology/cancer research. I have plumbed the San Diego formation for years on and off, but I am now trying to look out new spots in the area - particularly for Eocene era fossils from the Mission Valley/Stadium formation. My sense is that these are much, much less rich and exposed - but I want to keep snooping. These Eocene formations represented a time when SD was a floodplain, fed by the massive Ballena river that deposited a huge alluvial fan across the county (as I understand). Anyhow, just rambling and introducing myself. Actually, I had an account here in 2016, but since have lost access to it because of lost password and cant access old email. Old username was 'Cetacean'. Will post more stuff soon if folks want to look.

    Removing B72

    What is the best way to remove layers of b72 from a fossil bone, I know acetone works but is in best to apply with a brush, or can you pour or dip the fossil in the acetone?

    Cetacean? Shark Hill bone vertabrae?

    Found this several years ago at Sharktooth Hill in Bakersfield. Starting to go through some of the larger pieces I found. I’m thinking this might be a worn vertabra? Whale, dolphin? Maybe to worn for a definite ID

    Possible whale, or cetacean fossil bone

    Hi pretty sure this is fossil whale cetacean bone, found near Newport Beach California. Was looking for a second opinion. Also could I clean these pieces up with a soak in vinegar?
