Hello everybody. I went through one of my fossil sheds the other day, something I have not done for quite awhile now, but I dug through some old boxes and totes and along with a lot of other fossils I ran into this box of echinoids. I remember it was a trade and I remember they come from someplace in southern Cal. The darker ones I want to say come from the Bakersfield area? By any chance does anyone recognize these and cann help with any info would be great. Thank you RB

I had the privilege of digging for seven hours on a parcel that was once part of Ernst Quarry, but had long been sold. Here are the best items that were found. There was more of either the same or broken, not shown. The matrix was extremely hard and difficult to extract, but the hard work was worth it. One of the Hooked Mako's has tiny 2d manganese dendrites that grew on it. One of my other favorites is a pathological Cow Shark. The 3 sections of the Ray Plate are rare for Sharktooth Hill. There are some interesting micro teeth as well.

Help identifying some shark teeth from Shark Tooth Hill (STH) Bakersfield, CA
digit posted a topic in Fossil ID
A number of years back Tammy and I had a great day in the field digging for shark teeth at the Ernst Quarry in Bakersfield, CA. We were joined by longtime forum member Tony @ynot who drove down from northern CA to meet us. Those interested can read about that trip here: http://www.thefossilforum.com/index.php?/topic/60863-shark-tooth-hill-ernst-quarry-hunt-on-2016-01-22/ A number of the nicer loose teeth were wire-wrapped into necklace pendants and given away as presents and a few teeth still in the sandy matrix were prepped out for display (some of which are presently on display in an exhibit at the FLMNH display museum). The bulk of the rest of the interesting teeth are being donated to the FLMNH collection as the museum's collection was a bit deficient in STH material (a few larger teeth donated over 50 years ago). As these are going into the museum's collection I want to have good IDs on the specimens. The hooked Cosmopolitodus (Isurus) planus teeth are reasonably distinctive and I think I have a handle on at least the obvious curved uppers. The rest of them I am not certain of the proper ID and I'm hoping for some help from folks who are very familiar with this locality. I'm starting out with the larger white/mako teeth and then I'll be sorting through the smaller ones. If I have questionable teeth in some of the smaller ones I'll add additional photos. I've labeled all of the teeth with numbers and letters so that there will be no confusion in identifying which tooth we are discussing. Looking forward to getting these teeth sorted out and also learning a bit more about the shark fauna of a site that I've had the fun of collecting (if only once). Cheers. -Ken All of the teeth in image 1 look to be the Hooked-tooth White/Mako (Cosmopolitodus planus) and seem to be all from the upper right quadrant of the jaw. More help on these would be greatly appreciated: Thanks for looking. Cheers. -Ken.jpg.c256249032263bf07397d25c18b30292.jpg)

Greetings all. It looks like I'm finally getting my hands on a decent desmostylian molar from STH. While I'd prefer to have found it in the ground myself, I can make no such claim. It was a purchase. While easier on my back, the rewards are certainly less. But I'll take it. The images of the rootless tooth look like it has never even had the matrix rinsed from it, as sand grains are in evidence falling from the tooth. Does anyone have any dos and don'ts for preserving the tooth? I have dealt with shark teeth from the same formation and usually have no problem just rinsing them with a little scrub from my roommate's toothbrush. Should such treatment be avoided or duplicated? Thanks ahead of time. Cheers. -
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

My daughter and I did a paid private property dig outside of Bakersfield, CA in the Shark Tooth Hills last Saturday. We very much enjoyed it! Found 8 species of shark teeth (hastalis, planus, angel, dog, hammerhead, cow, and long toothed and normal tiger) and some extinct sea lion and porpoise teeth as well as some seal lion and whale bones and vertebrae. We loved it, but both felt it was a “one and done” and preferred diving for teeth over digging. It was also hot…well over 90 by the time we stopped after 7 hours. Lots of teeth and the owner dug with us and identified teeth/fossils as well as gave us the bulk of his and his son’s finds.

These are some of my Sharktooth Hill finds from 2019. Was wondering if the first pics are a vertabra? The other pics are a fish vert. Sharks vert. And a random cetacean vert. I suppose, sorry I’m posting so much , but I like that I can get some second opinions on my fossils.

Greetings all, As we approach the third anniversary of the loss of Doren "caldigger" Strane (RIP, my friend.), I am looking over some fossil pieces he gave me while standing in the Denny's parking lot at Merle Haggard Blvd in Bakersfield. For some reason this one struck me as looking more land mammal, like an equus of some sort. Or perhaps it is from a marine mammal and I just don't recognize the shape of the bone, which wouldn't be a big surprise. I do think that it's got a good shot at an ID other than "chunkosaurus", which was the ultimate ID of the fossil I asked about in my first post here 4-5 years ago. I'm pretty sure that it came from Bakersfield's Temblor formation, as that's where Doren got most of what he had. But I have not seen much, if any, land mammal fossils from there. I do know that Doren once found a little rodent skull that he donated to a university or museum for study. But I'm pretty sure that this bone isn't from a rodent of any type. At least of any type I'd want to run into in the flesh. Any ID ideas are greatly appreciated.

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.

Hope everyone is doing well. I miss being in a creek or on the beach, but all in due time. Every night I have been relaxing going through different types of matrix. Last week I started seperating ray teeth from Bakersfield matrix that I went through last week. I believe the these are three shark teeth that are not ray teeth. All measurements are in MM. Any feedback (as always) is much appreciated!! 1. This tooth has a little white nub sticking out. I was thinking something pathological like a smoothhound? 2. I am pretty confident this is a smoothound, mustelus lateral tooth. If it is, pretty excited because it will be a first of this type for me. Also it fell off my tweezers when I was putting it back in the gem jar. I am absolutely shocked that I found the little 1mm piece of.... happiness! 2. 3. For the last tooth I am stumped. It has a crazy perfect circle on top of the tooth. I was thinking something like a basking or whale shark. But what I have learned over the past year and half on the forum is, when in doubt... it pathological something something. Any feedback on this would be great. I hope this post helps future people looking at similar teeth! Everyone on this forum is amazing!

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 (left side, halfway down) and a sea lion tooth (top row, just right of center). The grid is my cutting board with 1" squares. At the end of the Sunday dig, I was checking out a previously started hole out away from the main site, across the road just before it makes a right turn to wind around to the parking lot, and pretty quickly found a nice Hooked White that, at the time, had a nice blue-grey tint to it. Rob told me that it's probably going to be a pretty good spot and let me park right next to it on the following morning. It was pretty darn good. The bottom section of the photo shows what I found on Monday, all from the same spot and without using a sifter. I stopped using the sifter halfway into Sunday- I just used the fan method with the shovel. I stand above the hole and cut away a section so it falls into the pit and then, one shovel at a time, scoop that up and fan it in my discard pile so I can see what's in it. Not as thorough, but you get through a lot more material, and anything big enough you WILL see. Also, my back was killing me from using the hand held sifters on the previous days. I made a previous post showing that teeth from Ernst don't just glow under long wave uv light (365 nm), but they phosphoresce (glow for a bit after removing the light). None of the teeth from the second site glow at all, except for a couple of the more orange-colored smaller ones in the lower right. Some of the teeth have a nice satiny, slightly pearlescent finish. Can't wait to go back!

Greetings all, I found this fossil near the flat parking area at what's left of the Ernst quarries. When I came across an image I took of it, I realized that based on the shape of the left end, that it might be an ulna from a small mammal, or? It has a shape that is somewhat similar (heel-looking section) to a mysticete, Tiphyocetus Temblorensis ulna, that I found at STH a couple of years ago. Or maybe it's just the remnant of of somebody's lunch from a couple of hundred years, the time it takes for something to fossilize (Joke)? I remember it was a fossil, so please take my word for it, at least until I find it, at a later time, and discredit myself. Any ideas based on formation, Bakersfield, CA Temblor, size, and shape? If more images are required for good ID, I'll track the fossil down and add them. Many thanks. Cheers.

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? -
Hi everyone, A friend found this bone with what looks like a shark tooth embedded into it while he was hunting in Bakersfield near Shark Tooth Hill. Does it look like an embedded shark tooth? and what type of shark do you think it could be from? He found several Hastalis and Planus teeth in the same layer. I really appreciate all the help the community has provided me. I learn something new every time. Thanks!

Hi everyone, I have a few teeth that I have always wondered about. I found another one the other day looking through washed matrix. Let me know what you think. Largest tooth is 18mm smallest is 9mm. I have only these three from all the years of collecting.
-
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 cleaning I was thrilled. I can see from those cracks why I've had such a hard time finding a complete one.

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. WooHoo! I used dental tools (nice set online for <$20) and small paintbrushes to scratch away the matrix. A super soft fluffy brush I found in my wife's makeup kit (shhhh!) was great for removing loosened silt. The matrix looks wet because I was dipping a finger in water and barely touching the matrix to soften it. Not too much though because that Sharktooth Hill matrix can be really soft. When I got more experienced I started using a small paintbrush to apply the water more carefully. Oh nooooooooooo! The tooth fell out. Does that happen to anyone else? I decided that meant the tooth just wanted to be cleaned so I took the opportunity. A quick clean up and a little CA glue and we are back in business. QUESTION: How do the rest of you actually get the tooth clean? There was no way I was going to be able to wash it or use a toothbrush or anything like that. I can tell myself "I like them a little dirty" but can't help but notice that some people get them really nice and clean. Any tips? Esp. with that STH matrix.

Hello, The indentions in these two pieces of Sharktooth Hill bone are very unlike anything else I've found there and I'm hoping someone recognizes them. Very smooth and very round, about 2-4 mm deep. I'm including pics of the backs of the pieces, not because they seem interesting, but just so you can see that they're not. It's a little hard to tell, but the large piece has a partial indention on one of the broken edges on the right side of the pic. Thanks for any insights you can offer! Larger piece - Front Larger piece - Back Smaller piece - Front Smaller piece - Back
-
I had no idea what this one was, probably just a scrap of bone but worth checking I think, sorry for lack of scale but it’s around 14 cm long it’s from STH (also I havent fully prepped it yet as I want to know whether to get someone with air tools to do it or do it myself)

Found this thing today in my Sharktooth Hill bucket-o-bones and my first thought was "fossil oreo" so I was very intrigued to learn that there actually are fossil "cookies!" I even think I found one (not posted here). But this one is a sandwich cookie. I have pics from top, bottom, and all around the edges. The large hole you can see from the edge view goes straight through all the way. If what I learned about "cookies" is applicable, I would imagine they would be like caps on the two flat surfaces of my bone, and are therefore missing on this specimen? So I guess it's a vertebra? Ideas on what animal, what part of the spine, (or how many million miles off I am) would be greatly appreciated. Thanks!!

Beside all the bone fragments I've seen from Sharktooth Hill, this one really stood out. I'm hoping that the relatively good condition it is in will allow for identification. Taking a swing at it, I'll say turtle but definitely not too sure. All 3 pics are the same bone. Thanks!
-
Sorry, but I barely know where to begin describing this. Happy to field questions or take different pics if that helps. What I DO know is that this seems much different from all the other teeth and bones I brought home from Sharktooth Hill. It is lighter weight than the other teeth and bones and seems to be composed of a pair of something with a plate on the bottom and sinuses in the back. The first pic shows what I'm calling the "top." Then if you tip that backwards you can see a smooth plate of some sort on what I'm calling the "bottom" And if you continue to roll it backwards now we see the hollow sinuses on what I'm calling the "back" side. Finally, here's a slightly different view from the front with it tilted just slightly upwards compared to the first pic in this post. Seems to be some wear on the edges pointing forward. Does this ring a bell for anyone? I'd sure love to know what I found. Thank you!

Hello, I am having some trouble IDing this tiny tooth found in some micromatrix from Sharktooth Hill. I believe I've narrowed it down to a smoothhound (Triakidae mustelus) or guitarfish (Rhinobatos) but of course others are probably possible as well. Thank you very much!
