Took a trip down to the Calvert Cliffs with the Buffalo Geological Society last weekend for some fossil hunting. It was my first time ever hunting at this location and I would call it a success. I can see why this location is such a popular spot, great beaches along the Chesapeake and beautiful weather made this one of the most scenic fossil hunting locations I've ever been at. The first day was Flag Ponds, which is where most people had better luck finding good sized shark teeth during low tide conditions. I found a small fragment of a Meg here, which was exciting. The second day was Matoaka Cabins, which was where much better invertebrate shells could be found. I took a walk a bit past a recent cliff failure and ended up having a lot of success finding teeth during high tide by churning up the sand and letting the waves wash it out. After I got a system down in the afternoon, this method yielded me a tooth every 5 to 10 minutes. I also filled a 3gal bucket with gravel deposits from the low tide to bring home and sift, I would not do this again as I only found a few teeth from this bucket. Looking forward to the next time I can get back. Total finds. Everything above the coral is from Matoaka, everything below the coral is from Flag Ponds Dolphin ear bone, probably my favorite find of the trip. Awesome preservation from what I have seen Some of the best teeth Some of the better ray fossils Crab claws Bones

From the album: Fin Lover's South Carolina Finds

I posted a thread discussing finding barnacles and seashells in the Peace River on Monday. I did have a few other finds and decided to post these separately... 1st -- a very small tooth that looks like deer but I do not think it is, and if it is not deer and in the Peace river it is very rare. Back in February, @Harry Pristis identified another small tooth I had found that was from a Pliocene deer, Eocolieus gentryorum... and it looks very similar, just a little smaller, but I need one more photo, I do not think this is Deer, I think it is Llama, and the only llama I can think of at this size is Hemiauchenia gracilis... Let's see what Harry says... 2nd up is a pretty small Dolphin tooth... I was digging in pea gravel,, small gravel generally leads to small fossils. A marine mammal periotic. Usually these are 30 mm, not 20 . I will be curious what @Boesse identifies it as.... When not hunting, I have been working most of the days, cleaning up and cleaning out my collection... NOT ENOUGH ROOM... While sorting the ones to keep, I found this in a ziplok bag from years ago.. It is about the same size and looks a little similar but did not come from the Peace River.. curious that I should come across these two 24 hours apart...

Went Hunting Tuesday, Opened a thread "Some finds" to discuss some of the more interesting finds to me. I had some additional finds and would like help in identifying them. They are harder than the initial set. Sorted out small shark teeth, ray teeth, etc... There are a couple of distressed Tridactyl horse teeth on the right, a shark vert so fragile it broke on discovery and also again after... First is a bone. When I saw it , I thought it was a Rhino metatarsal. It is not, but I have never seen this bone previously and that is pretty rare. That "slot" on the bone in the last photo is natural. The bone density and porosity reminds me of marine mammal... @Boesse The 2nd find is a dolphin tooth.... I found a similar small dolphin tooth at this location last June and trying to confirm (or not) that this is likely the same species. Third is a possible claw, I am wondering Armadillo, and we can always consider raptor. Bottom: Side: 4th, How about these small 13 mm rostral teeth? Are they Pristis .sp? They seem different from what I have normally found in the Peace River. Thanks for any and all comments, and responses. Jack

Out hunting the Peace River yesterday. Went back to a location we have hunted forever. Basically just depending the river continually moving the fossils around and dropping them in the same place. Wait for the river to drop making this location shallow enough to dig. I know most of what I found... Here is a photo, after removing the shark teeth.... and the few shark teeth I chose to keep... The Meg on the left is 30 mm, some tigers including a Mayumbensis and a broken... meg I think. There was a Tapir tooth with some root, a Croc tooth along with the gator teeth, and a cluster that @Coco Identified for me years ago, but just now I can not remember. There is a chunk of proboscidean foot bone I likely will not identify, a chunk of gator jaw, dolphin tail vert, a dugong/manatee partial skull cap, and a pretty nice Glyptodont osteoderm. But the things I like the most are a dolphin tooth and ear bone... I seem to be finding more of these lately... and that's just fine with me. For last is this canine or maybe canine. I think that I convinced myself that it is a whale tooth that is "spalling"... More than sufficient find to reward a day of hunting, and a surprising number given that I have hunting this exact spot of years...

Hi, went to the fleamarket and bought this. I think they’re some pseudosuchian teeth.

Hi found this vertabra on a beach near Los Angeles. Even though it is not a fossil I was wondering if anyone can ID it for me, I was thinking dolphin or porpoise but I’m not 100% sure. Thanks

Out with friends, going to a Miocene site that always is challenging for me to go and return. It is a Miocene site because the large majority of fauna found live during that era. It did not disappoint. I started in the 1st sieve with a Meg, somewhat distressed and puncture marks from a bite during a feeding frenzy... Note the 3 bite marks on the lower edge. This is my 4th such Meg There were many finds but one certainly rarer in the Peace River than Megs is a lower Mako in good shape, with a lighting strike on the labial side.. This is my 3rd of this size in 15 years. So, what about the request for Identifications. Here is one... This Dolphin Tooth has not been identified for Florida.... and certainly not for species.. Last time I found it , we discussed Harry's GREAT picture that is the best identification out there for teeth that look like this....If someone has a good research paper on Kentriodontidae teeth that matches these two teeth I have found, please point me to it... Here is my previous version: Here was a thread that asked for an ID on a similar tooth from Maryland, but the ID was "Dolphin" tooth... So finally, something to ID.. To show how my luck was holding, I went over to a pile of discard rocks from a previous hunter of this site . Unbelievably this was sitting on top... I have never seen one like this... Th first photo seems 3/4 Stingray denticle and 1/4 trilobite. I have plenty of these that are flat on the bottom, and found 2 or 3 today. But this is unusual for me in Florida. Is this shape common in Maryland or North Carolina ? It almost looks like a druzy or silification in the center of this last photo.. Thanks for looking.

Went hunting today. One broken Meg, One broken Mako but some interesting finds. I pick up lots of things that trigger my curiosity, like a coprolite or modern catfish barb, or even enamel fragments that have patterns that I try to identify. There are some rocks in this photo, but don't get confused. At 3 o'clock is piece of tusk, and 4 o'clock has 2 pieces of fossilized wood. Dolphin vert, a couple of dolphin bulla, a couple of processes from Baleen whale petrosal. Just goes to show, sometimes I do pick up fossils. I am interested in that likely modern bone at 7 pm... Here are some more photos. Those breaks look clean, like from a butcher's saw. Possibly, I'll learn to recognize this next time I see it.

Some good friends offered to take me hunting for a couple of hours today.. thank the Lord for good friends. It was only 2 hours but I found some unusual items... including a number of high quality dolphin small verts. Then this one showed up... unusual, meaning I have never seen one like it previously. It's a vertebrae and I thought this would be trivial-- just search the net for "fossil dolphin Axis Atlas vertebrae". No luck... So what is it ? Tail vert.? what?

Is this a whale ear bone? Age: Miocene Loc: Poland

When I was out hunting yesterday I found this fossil, I believe it is dolphin but I just want to make sure. (It's just over 1.5 cm)

Even though my muscles were sore and my tendons/ligaments were overused from hunting on Saturday, I had committed to a Peace River hunt yesterday. and a commitment , after all, is a commitment. So there I was at 7:30 am, launching from a Peace River Bridge with a couple of friends. It was bound to be a difficult day. The best location in the general area of where we chose to hunt was covered with softball (and up) sized boulders and had been heavily hunted by people who knew what they were doing. The boulders are the advantage. As we get storms and hurricanes, it moves gravel and fossils downstream. The fossils/gravel falls between the cracks in the boulders. All you have to do is remove the boulders. You won't find much, but usually for me , it is worth the effort, which turned out to be a little over 5 hours of shoveling boulders... So, the "everything" photo.... Pretty sparse, Up in the left corner rocks or overly worn osteoderms, In the right upper corner, marine mammal (2 broken whale bulla, 2 broken dolphin bulla, a frag of dolphin jaw bone, and an overly worn dolphin periotic) all a pleasure to find..I will be able to ID that periotic) Do the small whale bulla imply small whales ? maybe 10 feet at birth.... Right lower corner , an old glass fuse... Does anyone still make them? Lower left a couple of horse teeth, and a process from a dugong vert... These will go into a zip lock and donated at my next fossil club meeting with most of the small teeth. For the sharp eyed ones who spotted it in the "everything photo", my find of the day... Took a long time to get to : What am I trying to Identify .... A bone and possibly from the 1st photo, a toe bone or hoof core.... Size approximately L 30 x H 25 x W 20 mm. Thanks to all. Jack

Finding my favorites, Gomph, a Meg, Tridactyl horse, and a Periotic.. A enjoyable day in the sunshine with friends... The Meg came early but also found some nice Lemons, Tigers, and Sand Tigers. For identification, a couple of small Horse teeth... 1st has been slightly broken, but likely very identifiable. When we talk about the smallest of Florida Horse teeth, this lower must be a candidate. As we were picking thru the final sieves, this Cetacean periotic added excitement. It is the smallest one I have seen.. @Boesse Apologize for the brevity... Wanted to add this thread before cleanup and sleep... Jack

I was out today with @DirtyHippie. We have a great time and I came home with a Dolphin earbone and a pretty upper Hemi. I thought the earbone was Pomatodelphis inaequalis, from Hulbert's book. But, in close comparisons, I am not so sure. What do others think? @Boesse Here is a bulla that I had found in the Peace River that I thought was from Pomatodelphis inaequalis for comparisons.

Out again yesterday... A little cool ... 85 and overcast, starting at 65 degrees. Better choice than today high of 71. A 5mm wetsuit took care of that. A little deeper that makes many locations unavailable or cause you only to dig the top 6 inches... Not many out hunting, likely waiting for better conditions. With Hurricane Ian, lots of change, trees down, sections of the river cleaned out, sand and gravel moved around. My finds.. Not all that impressive until you look at a couple of my favorites in lower right..... I really enjoy marine mammal fossils like Whale teeth, Odd exterior pattern on this one... and a broken Dolphin tooth that has me wondering... Is this a long beaked Dolphin tooth or something else.... The one from 2017 is 23 mm in length. My find yesterday.. This is rare for me, maybe once every 2-3 years...

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: -
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

2022 in review: all of this year's advances in marine mammal paleontology
Boesse posted a topic in General Fossil Discussion
Hey all, it's been a decent year for marine mammal paleontology: I wrote my yearly blog post reviewing all of the new studies that came out. Check it out below: https://coastalpaleo.blogspot.com/2023/01/2022-in-review-advances-in-marine.html Also - some selected images of the more spectacular marine mammal fossils described this year:

I was able to meet with Daniel and his parents at a pay site on 12/3/2022, and the finds did not disappoint, at least for me. First of all, Daniel and his family were amazing folks. His parents were probably closer to my age, maybe even a bit younger, haha. That said, Daniel’s playlist was spectacular, it was late 60s and early 70s soft rock, it made the trip extra special. This was my first time to this site, and clearly a different type of finding fossils. Working for them was harder than I expected, but not too difficult. Here is are my three favorite finds of the day. And thank you again Daniel, I look forward to another trip early next year.

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.

New blog post! A guide to whale and dolphin earbones - part 1
Boesse posted a topic in General Fossil Discussion
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: -

Miocene era deposit, east coast south island New Zealand. Ribs of some kind - dolphin?
inyenzi posted a topic in Fossil ID
Hello, I found this bone cluster in a Miocene era beach deposit on the east coast of the South Island New Zealand. Appears to be ribs of some kind, 5 in total. Perhaps some sort of dolphin? Any help identifying the type of animal this came from would be much appreciated. Scale is in inches. Thanks!
