Hey, been a while, so i decided to start a new topic for the new year. Headed out on Thursday 25/01 to the river shores in Antwerp again. First hunt of the year since i've worked non-stop so far and a contractor is rebuilding our house.. It was great being out again so i was already pleased on beforehand, finding some nice teeth made it even better 😁 here's some in situ pics.. Rolled C. hastalis C. hastalis in excellent shape my first Parotodus benedeni ever, not in great shape but an awesome find anyway 😀 Finally a complete 6cm C. hastalis VID20240125131132.mp4 And some random mammal teeth Had a great first hunt of the year, and I already feel like going back! oh yeah, here's the whole lot cleaned up.. Surprised about how many different species i got covered this time 😄 Grtz, Dries

I'm curious about what I believe are charybdis fossils from Indonesia. I'm slightly suspicious of the matrix, but also know that most of these fossils are in clay and could dry like that. Any feedback is appreciated! Thank you and have a good day.

I finally finished out sorting my GMR matrix and I have a few small shark teeth and the like that I’m interested in! 1) 2) 3) 4) Reptile hopefully? 5) hybodont? 6) 7) 8) 9) 10) 11) I shared this with Dr. Shimada, who thinks its Cantioscyllium or Plicatoscyllium? 12) 13) Ray crusher plate? 14) Catshark? 15) 16) 17) 18) 19) 20)

Fossils labeled as from East Bluff, California but not so sure if that’s correct
Guest posted a topic in Fossil ID
These were sold to me stating they came from the East Bluff area in Newport Beach, California. But research into fossils from that area comes up with late Pliocene material that doesn’t look anything like these. The serrated tooth is especially confusing. Any ideas?- 5 replies

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

One of my favorite Lee Creek finds, a nice seal jaw with 5 teeth. This must have been a fairly young individual because there is almost no wear on the teeth. -

Started going through some of my older finds and thought I’d try to identify some of them. These are all found in Gainesville, Florida creeks. First one is just a chunk of bone, not sure if it’s even identifiable. My guess is part of a scapula because it’s somewhat flat and curved. Second is a small bone, maybe a carpal of some sort? And third, I’m thinking is a partial alligator tooth. I can see a small bit of enamel left on it, but the enamel seems to have some ridges on it which is confusing.

“Tiny Bones Project” So these little perissodactal and artiodactal carpals and tarsals are a tricky bunch to navigate. I'm only dealing with 5-6 species so far and it’s already bonkers. As such making a thread dedicated to the ID’s of some more common fossil finds seemed worth making. Especially since this project involves making a “touch Catalog” and photo library of them for me to use in future ID’s. Why not share the information? Lord knows I’m getting plenty from y’all! When the results of a group are completed, and have been reviewed by the forum, I’ll post the final revised report and photos here. My idea for this thread is to compile the various existing photo examples of these bones from TFF and the new photos of these bones from my collection. Once my stash is exhausted I’ll hunt for others to study and if TFF members have examples I don’t they can post what they want to add and share too. Finding “exploded” joint images to study these bones individually online proved unsuccessful. Most studies are interested in the articulated version of these groups. So searching for individual bone examples leads you right back to our own Harry and his incredible image galleries. Hopefully I can merge new stock photos with Harry’s confirmed gallery images and also include the bone images often presented for ID that Harry’s galleries are used to authenticate. Harry's post show up in Google because his galleries are used to ID so many things. We search specific things so we just end up back at Harry after a few clicks. If TFF is the end location for identification of carpals and tarsals let’s collaborate the efforts into one powerhouse of an ID catalog. This project got its start because I have been looking for random carpal and tarsal fossils for an Equus sp lower limb articulation project. I quickly learned getting positive ID’s when trying to purchase these types of fossil are not common. Most are listed generically or even incorrectly. So I figured I’d document the hunt to look back on later. The Equus project needed a single bone from a large auction lot of mixed fossils. After a good bit of rationalization I realized buying 50 bones to get 1 was a little silly. However, I had roughly ID’d several “shapes” of scaphoid bones which got me interested. Then I realized I had multiple versions of the same bones in various stages of erosion and that’s when the idea light came on. “Buy them all and learn from it!” So the main goal is identifying, labeling and photographing. With attention added to photos that can show multiple erosion level examples together. Gonna take a bit but that’s why I have lots of projects. Little here. Little there. And every now and then I’ll upload a new group for review. Im learning so be patient! If I use a word incorrectly or need revision it’s ok! Just tell me and I will happily increase my brain mass and correct the thread. It does need to be cohesive and I will need assistance with. Keep the faith and try to do good! Jp Disclaimer: Do not watch this video with and kind of beverage in your mouth as my pronunciation of these words is most likely laughable 😊. I also called the camel unciforms, pisiforms and had already cleaned up before I realized it. Pisi about that blunder to say the least. 😉 FullSizeRender.MOV

I went fossil hunting yesterday. It is an activity that brings a smile and renews my soul. Sometimes I like the solitude of hunting alone ( my 1st 18 months I only hunted alone), but this day I was blessed with good friends and I could tell stories, share their cut up fruit and trail mix, and marvel on what we were finding. These are mostly my treasures.. None of us found large quantities, I had less than 50 fossils in my collection bag... but what we did find was unique and/or had some quality aspects... A tiger , 32 mm across the root. A Dusky or Bull, never sure which A fishjaw and a Tree root.... and below, a rare find for me ... note it tried to break,. it will not get the chance again A dolphin tooth found late... not one that I could name. Friends also found a Dolphin tooth earlier, Slightly larger. When this rolled into my sieve, I knew it was familiar, I rolled it over and over, but I was not expecting it , could not ID. My friends did. Menippe was a Genus of Stone crabs back in the Florida Pliocene. I wonder if this was a late arrival. I liked the quality of the fossils... look at the details of this crab claw... I was picking up a bunch of (broken) bones that I only slightly recognize with the intention of posting some of them but maybe in future posts. I do have a femur that I am curious about... I always search TFF for helpful threads: http://www.thefossilforum.com/index.php?/topic/102805-peace-river-femur/ It has this comparison photo.... For comparisons, I possess a SaberCat femur at 13 inches if complete. Here's the key: 1-Horse femur, 2-Sabertooth Cat femur, 3-Human Adult Female Femur, 4-Komodo Femur, 5-Harpy Eagle Femur, 6-Kiwi Femur, 7-Platypus Femur, 8-Spider Monkey Femur, 9-Rhesus Macaque Femur, 10-Vervet femur, 11-Goliath Frog Femur, 12-Flying Lemur Femur. The bone seems not sufficiently robust for tapir, horse, llama, cow,, so maybe deer, coyote, bobcat.... Here is a mule deer for comparison. I think total length of Mule deer femur would be 11-12 inches. Any suggestions will be followed... Thanks for reading...

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?

When did baleen whales become large? New blog post - The Coastal Paleontologist
Boesse posted a topic in General Fossil Discussion
Hey all, I realize I've been incommunicado quite a bit this year - it's been a bad one. Things got real bad at the office and both my wife and I resigned from our department and we've been working for a new nonprofit in Charleston. But, I AM alive and returning to active status here on TFF now that 1) the forum has been upgraded and is functioning and 2) I've had some breathing room and time to unwind after leaving a deeply toxic work environment. I've also made a conscious effort to get back into blogging more frequently and have written/posted quite a lot in 2023. My most recent post summarizes a bit of an interesting and ongoing debate in whaleontology: when exactly did baleen whales become gigantic? Anyone who has spent any time in the Pliocene of the Carolinas or Florida knows that baleen whale fossils that are only a few million years old are nowhere near as large as the gigantic skeletons of modern whales hanging in museums. So, what gives? I've written a blog post that goes into a fair amount of detail regarding competing ideas for the evolution of body size in baleen whales - shown above is skull width of archaeocetes, odontocetes (toothed whales) and mysticetes (baleen whales) through time. Read the whole thing here - please enjoy! And don't hesitate to ask questions, here or on the blog. https://coastalpaleo.blogspot.com/2023/12/obscure-controversies-in-cenozoic.html -
