Identification Teeth of C. hastalis closely resemble those of the modern "great white" (C. carcharias) in having erect triangular cusps, no lingual dental band ("bourlette") or a thin one, and no nutrient groove. Differing from the extant species, they have no serrations on the edges.

Historically known as "makos", we now recognize C. hastalis as being ancestral to the modern great white shark. -
Unique wood from Round Mountain Silt, anyone seen anything like this?
H. Drax posted a topic in General Fossil Discussion
Been going through an old collection I haven't looked at in many years and in it are 15 or 20 pieces of wood, collected at the Ernst quarry back in the 90s. I haven't seen any similar examples from Sharktooth Hill or elsewhere. The pieces are somewhat fragile and often partially hollow with small (druzy?) purplish crystals on the interior. The rest is mostly composed of the same purplish-black material but man also show a tougher translucent outer crust. Some of the interiors of these pieces also contain powdery, lightweight chunks of brown matter. Based on appearance -
I recently got this unusual, at least to me, marine mammal tooth. I am pretty sure it’s Pinniped but beyond that I’m not sure. Marine mammal fossils are not something I have a great deal of knowledge about. I suspect it could possibly belong to an Odobenid as opposed to Allodesmus. I have never had any teeth from the STH Walruses in my collection so I’m going solely off some research I did. It’s a really cool tooth whatever critter it belonged to. Any thoughts ??

Are these lemon shark teeth? Or black tip? Or something else entirely? How do you tell the difference between lemon and black tip shark teeth? These are from the temblor formation, slow curve ernst quarry.

I went to Sharktooth Hill this past weekend. Most were found in the flat lands next to the parking lot. The bottom row were found on the hill, near the port-a-potty. The hill finds have shiny enamel and better color, but the roots are more brittle. All were found in one day.

Well, I am out here in Mojave, CA for work for the next 6-12+ months and since I cannot dive for fossils like I can back in Florida, I might as well get back to my roots and dig for them again. I am all set to go April 2nd & 3rd. I hope to see/meet any fellow members. I will be in my gray Jeep Grand Cherokee with Florida veteran Plate. I will try and document this trip and share it as much as possible. I figure I would make a list of items to bring, I welcome any and all comments from those that have done this before. First I will have a large straw hat

This is from the temblor formation, Sharktooth Hill. Let me know if better photos are needed. Posting photos from my phone is unpredictable. These tiny teeth (?) are on silt matrix. Whether they are prepped depends on an ID, as the silt is rather loose. There seems to be some chance that bone is beneath what is visible. one bit broke off, and might be glued into position. Below the Section remaining on the matrix, appears to be more teeth of a different shape or angle, which are partially shown in the final photo. I’m grateful for any help with the ID, or prep suggestion

Hi, everyone! Got back to New Jersey on Tuesday, after a weekend at Ernst Quarries. This was my second trip to the site, the first was back in 2018. The weather was perfect- not too hot and cool towards the late afternoon. All three days were pretty well booked, as far as I could tell, but most everyone seems to leave by 1 or 2:00. Met a bunch of great people, and I think I had a really good dig. In the first photo, the top section shows everything I found on Friday and Saturday- all but 2 or 3 from the same hole in the "main" area, including a section of leatherback turtle shell

Sharktooth Hill Trip Report Part 1 – building the sifting table Hi everyone, After my first trip to Sharktooth Hill in June, I was hooked. I immediately started making plans to return and, this time I’d come better prepared. This forum has provided an amazing source of ideas and helpful people and inspired me to build a sifting table for my next trip to STH. A huge thanks to those who have helped me by answering questions, providing pictures and ideas, and helping me troubleshoot. I gathered as much info as I could and then tried to combine all the best ideas into

Looking for advice about shark tooth hill! TIA
PrehistoricWonders posted a topic in Questions & Answers
Hey everyone! Going to STH somewhat soon, I plan on going to Ernst quarries(or if anyone has any other sites they’d recommend), and was wondering if there were any tips anyone could give me, since This will be my first time. Also, are there safety instructions they give you when you get there? -
I have had this STH tooth for awhile but I can not identify it. I have assumed it has to be either a hastalis or planus. When I first got the large group of teeth that this tooth was in, I set aside as I thought it might be Parotodus. I quickly talked myself out of that ID. I talked myself into hastalis or planus. I have looked at teeth in my collection and can’t find an exact match. I checked Elasmo and same story. My best guess is lower planus. It is just over 1” on the diagonal, pretty thick root. Any thoughts ???

I am still not back to work so I’m pretty bored and don’t have new micro matrix to pick through so I have been examining some STH micros I found in previously searched matrix we got from @JBMugu awhile back. One of the denticles I found stood out from all others. I only found one of this morphology in all the matrix I searched. I set it aside in it’s own bag in with the other denticles. I forgot about it until a search for papers on Echinorhinus fossils. I saw a photo of Echinorhinus denticles and I remembered the denticle I found. It looks so similar that I think that is what thi

Looking to trade for Unprepped or Trace/track Fossil material
Paleome posted a topic in Member Fossil Trades Bulletin Board
I would like to trade Trachydomia spp. snails for any legally-collected rough or trace/track fossils, from any era, any location. Here are updated images of what I have left of Trachydomia spp.. The first three in the front have been lightly coated with a clear acrylic (?). The other image is of Desmostylia tooth fragments (Langhian Miocene) from Sharktooth Hill, near Bakersfield, CA. These were obtained at a local rock and mineral show several years ago. I tried to get these to fit together to make a complete specimen. The only -
Can anyone ID these?

I have found several smaller fragments before, but never an intact one. This one turned up at the end of a very long day and I fortunately spotted it as my son was shoveling matrix into the sifting table. I startled him mid-shovel by shouting "STOP!" when I saw a row of white points sticking out of some matrix. Son was just about to throw another shovelful on top of it. Nice reflexes by him to change course mid-air to avoid me (now shielding the tooth with my body - LOL). Worth it. :-) Definitely had potential but I didn't know how much root was going to remain. After some careful

Despite several visits to Sharktooth Hill and hundreds of teeth, I've yet to confirm a shortfin mako (Isurus oxyrinchus or is it Isurus desori?). Perhaps this is a possible candidate. Or maybe another C. planus or C. hastalis lower. To me, the features that make this one look different from those other common STH teeth are that it is relatively long with a narrow base/wide root, and also that little bend at the tip when viewed from the side (I think it shows up in the bottom two pics ok). It just stuck out as "something different" and I was able to eliminate a lot of other possibilities. So ma

I recently had a chance to try my hand at a few matrix pieces from Sharktooth Hill. I'm happy with how they came out, although I know I could do a better job next time. Huge shout out to @digit and @ynot for their advice and encouragement. I think the thing I appreciate about matrix pieces like these are that prepping them this way can turn a rather unremarkable tooth into something unique. Anyway, I had fun doing it and I was encouraged to post a "trip report" so here goes... Here's how they looked when I got home. Nice to find out the tooth was intact. W

As I’ve gone through the donation of STH material we received, I have found a couple of shark teeth that I can not ID. My picture capability is limited to my phone so I apologize for picture quality. I thought the first tooth looks something like a Hemipristis symphyseal tooth but I could be off base. It appears to be a complete tooth as I see no evidence of the root being broken.
