    Beluga and more

    Went hunting yesterday. We have had a lot of rain and the Peace River is 3-4 feet too deep but it has been dropping and just due to withdrawal symptoms, we decided to try one of the streams that might have some low spots. The lighter colors tell you these are from a stream. That is a dugong rib segment upper right, mostly small shark teeth, a couple of Meg Frags, chunk of Mammoth plate, puffer fish mouth plate bottom. A Beluga periotic made my day. They are far rarer than Megalodons.. Only my 2nd in 15 years... the 1st was October 2021. There are other notable finds: A very small dolphin tooth (I will try to identify it, just based on size likely a small river dolphin). A Sawfish rostral tooth and then what I am trying to get identified.. a 31 millemeter enamel fragment with a unique tip. Additional Photos... This last photo of what I thought was the root end seems to have a chewing surface like enamel, so the "tip" above might be the end of a tooth root ??? This may be obvious and I'll but I have seen LOTS of broken enamel over 15 years. For example, that very thin broken enamel is similar to broken horse teeth, but I have not seen a tip that looks like this one on any Bone Valley tooth. All suggestions greatly appreciated. Jack
  2. Hello everyone Below are some finds from my last trip to a dredge spoil island that has Miocene to modern marine and terrestrial fossils. The dredge and river action unfortunately beat up the fossils and make it hard to ID. The scale on the white graph paper is 1" for the boxes. Photo quality a little off due to the poor winter sun angle. Large Un-numbered Bone: Possibly a mammoth or bison femur? Weighs more than 3.5 pounds. It looks like the head of a femur and a heavily worn limb bone. May be too far gone to ID. #1: Two small mammal (likely cetacean) periotics #2: Edge of a Turtle shell? Just didn't see the typical interior turtle shell texture #3 Broken coprolites? Interesting interior compositions on them #4 Worn turtle nuchal shell? #5 Wild guess-fish tooth in jaw? Has a smooth enamel on the pointy end that tapers on both sides to a broken point #6 No idea-Probably unidentifiable? #7 Small broken horse scapula? Thanks for looking. Hopefully the photos stay in order, with an outdoors photo followed by another photo indoors due to the outdoor light this time of year. Be happy to add better photos if requested.

    Too deep, too cold

    Due to the holidays, my last time out was 2 weeks ago. The nights have been cooler lately and we had some recent rains. Yesterday was sunny/overcast highs in low 70s F. I went out yesterday to a favorite location. Took a 5 mm wetsuit which was not quite enough to avoid occasional chills. The water was deeper so I could not quite reach the gravel and moved to a spot that had smaller gravel, more sand and shell. I recall thinking I might just try a sieve or 2 here and then move upstream prospecting. So much for that idea. In the 1st sieve was a tridactyl horse lower tooth. I would hunt here for the next 6 hours. I was finding fewer fossils than normal at this site, but the quality was better. For example , instead of 250 small shark teeth, I found 50. There were many broken bones and I kept a few that had potential for identification. In searching for comparisons, I found a @Plantguy thread where he was looking for IDs on horses, tapirs, and filefish. @Harry Pristis help out on differentiating Tapirs.. https://www.thefossilforum.com/topic/76697-florida-vertebrate-unknown-questions/ I wonder if Chris ever IDed his tapir. A few closeups of what I believe are accurate IDs looking for comments. Early in my hunting days, I found an almost complete 3.5 inch Ray barb... Any time I see one near 2 inches, it makes my day An upper hemi around 2 inches, even broken is a welcomed find One of the best filefish verts I have ever see, Look at the detailed lines on the inside of the centrum.. Nice tooth.. HSB traverse lines on the enamel. I say peninsulatus based on the age of the location AND the long time ratio of peninsulatus versus any other Tridactly at this site. There are at least 6 species of tapir in the Florida fossil history, I have found 2-3 of them at this location, but this ones looks a lot like Tapirus haysii, much more than others . That was the show and tell part of this thread... Here is the request for ID. I know that 1st photo looks like a conglomerate rock.. I almost tossed it, then turned it over to see the 2nd photo and thought maybe Dolphin earbone, At 16 x 11 mm, really small. What do you think?
  4. Hey all, Part 2 of my blog series on whale and dolphin earbones is here - my guide to identifying isolated dolphin/toothed whale (Odontoceti) periotic bones. Check it out here: https://coastalpaleo.blogspot.com/2023/01/bobbys-guide-to-whale-dolphin-earbones.html Sample image:

    Playing in the mud

    When the Peace River is too deep, I sometimes try land hunting and fortunately I have very good fossil friends who make me smile when I see them AND who have the skills. My son and I got together on New Years day and had a great time sloshing in the mud and making a memory. The mud turns to concrete when it dries on equipment and boots and it took more than a few hours to get cleaned up. A couple of nice finds , one to try and ID. The 1st is a nice little Meg that I sent on to my grandson in Texas. Liked the Olive drab color in the sunshine. The 2nd is a small dolphin periotic. This is gorgeous, looking at the unworn tiny lines still visible 3-4 mya later. They say that identification of cetaceans from periotics is a "black art" and I am not the magician. I get it wrong more often than not. But I have seen earbones before even from this locality. How about an ocean delphinid, maybe a Bottlenose dolphin , Tursiops .sp like this one , somewhat smaller, 4 years ago. There are always differences but there are a bunch of similarities also. About a year ago , @Boesse stunned me by Identifying this one as possibly Beluga Whale (HERE in Florida ). Could not have been more pleased. Note that it is about the same size as my new find..... Life is good, and we each have a whole new year to make great memories. Jack
  6. Found this little fossil on the James River shoreline near Surry, Virginia (US). Wondered whether it might be an incomplete dolphin ear bone, but not entirely confident in that ID! It's just about an inch long.
  7. Hi all - it's been a while, since I started on twitter and started teaching much of the itch I scratched through blog writing was taken care of by twitter - but now I've thought about returning to more long-format science communication. The blog format is certainly more informative for most fossil collectors anyway. The new post is just the first in a series on whale and dolphin earbones - the first is an introduction to the basic anatomy and function of earbones, along with basic differences between baleen whale (Mysticeti) and dolphin (Odontoceti) earbones, with comments on their preservation, discovery, and their uses in cetacean taxonomy, cladistics, and studies of diversity. The next post will be the one most anticipated by the majority of collectors - a guide to identifying dolphin periotics by family. The third post will be similar, but directed towards mysticete periotics, and the fourth will cover mysticete and odontocete tympanic bullae. Read it here: https://coastalpaleo.blogspot.com/2022/12/bobbys-guide-to-whale-dolphin-earbones.html Obligatory photo of some periotics we collected out on Charleston harbor on Dec. 1, well worth boots full of freezing cold water:

    Different ages, same site

    I was out hunting yesterday to a miocene_pliocene site that produces mostly small shark teeth with occasional surprises. In this instance there were three. 1st up... Upper molar Nannippus aztecus (11-5 mya) upper molar. Certainly Nannippus, likely aztecus based on size and location. Next , my unknown, a dolphin periotic earbone, 29 x 16 mm well worn and found in a miocene site. @Boesse And finally a Bison or Bos lower m3 unerupted enamel cap .. no roots. I was quite excited seeing the complete enamel in excellent unworn quality. But based on size and lack of wear, it is probably Bos... Looking for any different opinions

    Dolphin Periotic

    I am blessed to(still) be finding a few interesting but small fossils. This 1st one is a very high quality horse ear bone, and the 2nd is a clump of silicified coral with a little Botryoidal druzy growing inside. I always enjoy sharing these. And ... the last is easy. It is a Dolphin earbone (size 33 x 18.5 x 11 mm) ... a periotic. But I want to know which dolphin. and for that I need an experienced eye. @Boesse I hope that I have provided enough views. It might be a number of different Marine Mammals. See this recent thread to understand why I ask for assistance on most of these.
  10. Hello all! Sorry for the not-so-great photos here. My phone camera is... kind of a fossil. I found this mystery fossil on the beach in North Carolina, USA, somewhere near Emerald Isle if I'm recalling correctly. My best guess is that it's a periotic bone from a dolphin, porpoise, or something of the like, but it doesn't totally match up with images I've seen. I've also considered that it could be a ballast bone, but again, hard to confirm via Google search. Any thoughts would be appreciated!
  11. Got out to the Peace River yesterday and a beautiful day it was! The river continues to be very low and slow moving. As I was heading east on the 1 hour drive I was listening to news reports of several Florida Mayors wanting the counties or state to issue stay at home orders. This would certainly put a damper on visits to the river, I travel through 3 counties just to get there. So I hit the river thinking this could be my last outing for a while. With very few people on the river on any week day there really isn't a reason to stop folks from getting out and enjoying a day of exercise where they won't be in close contact with anyone else. As I was approaching within a few hundred yards of my most recent hunting spot I saw a tent on the river bank and a canoe alongside. As I got closer I saw a man and what I took to be his son. We exchanged greetings and the adult said he had spent the night on the river to get his son out of the house. I continued on and shortly had to get out of the kayak due to the water level being too low to paddle. I set up south of where I saw the campers and got busy digging. Various shark teeth started turning up pretty quickly. I was also rewarded with two small sections of dolphin jaw bones, mammoth and mastodon fragments and more. Every time nice finds seemed to be dying out I would come up with another nice shark tooth or a piece of mastodon tooth that convinced me the big prize was only a shovel away. Unfortunately, these turned out to be a bit of a tease. I did have a good day with the number and variety of shark teeth, a piece of deer antler, puffer fish mouth plate, whale tooth, dolphin periotic, a nice turtle scute, some sting ray dermal scutes and a small gator tooth. About 10 am I looked up and saw my friendly 4 foot gator lazily swimming by about 20 feet away. He slid under a downed tree and left his tail sticking out. He was there for about an hour and then disappeared. We seem to have an understanding, I ignore him and he ignores me. This was backed up by his return in the early afternoon to crawl up on his favorite sandy spot and watch me for the rest of the day. He was still laying in the sun when I headed north back to the launch site. On the way back a Bard owl graced me with his presence by suddenly flying in and landing on a tree limb directly over me in the river. He patiently waited while I circled under him taking pictures. A short time later I saw a 10' to 12' alligator slide into the river a little ahead of me. When I see that it does cause me to have second thoughts about my inflatable kayak! Shot of the owl and picture of the best finds of the day are below. I will be posting the whale tooth and one other questionable find in the ID section for help with an ID. Right now the plan is to return to the river Friday. Hope the politicians don't shoot that idea down with a stay at home order.
  12. Hi, just going through some rocks I brought back from Norfolk, UK, thinking quite a few may be fossils (I didn't have long so just grabbed anything I thought looked suspiciously organic by intuition) and as it turns out I think I was quite correct in a number of cases - I think I have quite a few pieces of whale and and a few little bits of mammoth tooth. Trying to confirm this to myself led to a lot of reading and learning online about the local geological formations involved and also whale anatomy, both new topics for me which I always enjoy delving into - part of the enjoyment of fossil hunting for me - I'm less of someone looking for beautiful specimens for display (though I'm not going to turn those down!) and more someone who loves the detective work of trying to identify obscure parts and recreate some aspect of the vanished world before us from its traces. And searching through whale anatomy and what these weird chunks could be I came across a picture of a whale periotic and realised that the weird little pot structure I had was almost definitely one of these, which if I am correct is good because I believe they are one part of a fragmented whale anatomy that is quite diagnostic. Also I then realised that a strangely hooked piece I found right next to it could well be the tympanic! The preservation here is unusual because many theorise that these kind of whale fossils were first laid down in sandstone in the Miocene when Norfolk was covered with a shallow warm sea, and then later in the Pliocene and early Pleistocene when temperatures dropped sea levels dropped too and the area became land (part of the reason the geology of this area is interesting is the constant transgression and regression of the sea over a few million years), these Miocene rocks were eroded away and the harder fossils reworked into new estuarine or nearshore sediments of this era, often but not always with a layer of hard iron-rich concretion coating them which helped protect them (I guess one question would be, is there anyway of easily removing this hard concretion layer?) So if I am right, these are bones from Miocene whales (many showing signs of shark damage), reburied in the Pliocene / Early Pleistocene and then finally eroded out again in the modern day - quite a journey! Anyway, enough background, for starters I'd love to see what people think about this periotic / tympanic. Am I right? Here's a summary of my findings (note I used a pic of dolphin periotic someone posted here for comparison so I hope that isn't too cheeky)
  13. I have spent many hours on this forum, but this is the first time I am posting because this inner ear bone has me completely stumped. It is the first inner ear bone I have found, and it appears to be the periotic of a small/medium cetacean. I see strong similarities with some dolphins and pygmy sperm whale specimens also pulled from the Peace River in Arcadia, FL, but none that really match up. I am new to identifying anything beyond teeth, but I was excited to find this and would love to have a better idea of what animal it is from.
  14. I finally made it out in July to a location near Charleston I am always mentioning, but had never personally visited. After 3 dry years of no ear bone periotics they started showing up in triplicate this summer. Probably was able to discern their shape better after seeing so many examples. Not much else showed up for me that day save a few tiny teeth. But it led to my first, albeit small donation. Common or Scientific Name: Odontoceti indet. (delphinid periotic ear bone) Geologic Formation: Undetermined - ( Fossil dredge from this site typically contains Oligocene Ashley Formation, Lower Miocene Marks Head Formation, Lower Pliocene Goose Creek Limestone, and Pleistocene Wando Formation ) Geologic Age: Undetermined - Oligocene (?) But potentially Pliocene - Pleistocene Region the fossil was found: Charleston, South Carolina Museum or University that received the fossil: Mace Brown Museum of Natural History at the College of Charleston Reason for donation: Well preserved and perfect for the fossil survey. Found and donated (July 23, 2019) to Dr. Bobby Boessenecker Dr. Bobby Boessenecker - " Ashby (Gale) and I (but mostly Ashby, since he's out more often) have been putting together a collection of riverbank ear bones from West Ashley, Johns Island, and Mount Pleasant, and this is quite a well preserved one that would go nicely into the eventual paper. "
