  1. Unknown STH teeth

    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.
  2. STH fire zone hemi’s

    Hey, I was wondering if it’s possible to find fire zone hemi’s in STH, or not? TIA
  3. Carcharocles megalodon (Agassiz 1843)

    From the album Pisces

    5cm. at the base. 4cm. high at the tip. Posterior Miocene Found at Sharktooth Hill, Kern County, California Thanks to Tony (ynot) for this one.
  4. I collected these at Shark Tooth Hill quite a few years back. Pretty sure the big one in a pinniped (Allodesmus?) limb bone of some sort, but not sure which one? The fish vert I'm guessing came from something pretty large too. Any insights or comments will be appreciated.
  5. Cosmopolitodus planus Bakersfield

    From the album Cenozoic Sharks

    Colorful Cosmopolitodus planus from Bakersfield, California
  6. Cosmopolitodus planus Bakersfield

    From the album Cenozoic Sharks

    Colorful Bakersfield, California Cosmopolitodus planus
  7. Oh, and one other tooth that I (actually my dig-happy girlfriend found the Tiger) found at Ernst yesterday. It looks like a relatively common lower Mako, but has such a bulbous root on it that I originally thought it was the elusive Paratodus Benendeni. However, it not having a bourlette leads me to believe that it's truly a false, False Mako. Thoughts? The blue cube is 1" square. Many thanks. I just realized that the false False Mako even has a false bourlette (Mineral staining) on it.
  8. Took a jaunt out to Shark Tooth Hill area, Ersnt Quarries to be specific, yesterday. Not too productive, but a few decent Makos, a little (7mm) fish vert, and the one inquired about here. It has the look of a Tiger shark of some sort, but is only 11mm across the root (cube it's on is 1" square). It has serrations on the cusp(let), distal and mesial sides. I don't recall the Galeocerdo Contortus I've seen having all three surfaces with serrations. It looks a lot like a Hammerhead, but I don't see serrations on the distal side on the crown on it. Can someone tell me what this is? Many thanks. Cheers.
  9. After posting ID questions on a couple of STH whale bones that were mostly unidentifiable, I decided I'd post images of the one whale fossil I have that seems like a slam dunk ulna (Aside from an easily ID'd ear bone.). It may be debatable as to which specific family category, but at least its location on the whale is pretty certain, right? Too bad it's a partial, but it's all I have. It looks a lot like one that is called Tiphyocetus temblorensis in an image from the California Academy of Sciences. Tiphyocetus Temblorensis Even the mottled coloring is similar. As I mentioned, this specimen is from Bakersfield, Shark Tooth Hill area specifically. While people may have seen a fair number of these, I thought it was cool enough to post an image or two of. And, people will be happy to know, I don't entertain any thoughts of its being part of a whale jaw. In fact, I'm over-jawed about having this one. Cheers.
  10. And so I return with another question about a particular, probably cetacean, bone. In my last adventure, we ascertained that a piece of bone, with cylindrical resemblances, was from a rib. With how little curve it had along it's length, I suspect it was from a large creature. I also have another interestingly shaped/textured bone fossil from the same general, Miocene, area in Bakersfield. As you can see, the glued specimen is a bit over 150mm in length, and sits about 70mm wide(tall?). One side is very flat along the length of the piece. Since it has what appear to be termination points, I figure that a general ID for body position might be possible. This is where I again go to thinking a possible jaw part. Like perhaps the rear portion of a mysticete lower jaw? I know, there I go again. As I said, the texture is not smooth like the rib I was given. It's got a lot of bumps and shallow crags around the curved portions. Thanks ahead of time for any input on possible ID. Cheers.
  11. Greetings, all. Recently a friend gave me a rather large chunk of fossil bone from the Shark Tooth Hill area of Bakersfield. While originally we thought it might be a rib bone, I now think that it being so straight for the length it is, as well as the larger radius, that it might be a piece of a jawbone. Perhaps a partial jaw of a Miocene baleen. Mysticete? Perhaps there's no way to tell? Any opinions are appreciated. Thanks ahead of time. Cheers.
  12. Bakersfield display

    For your viewing pleasure I present one hundred cleaned and placed shark, pinniped, Cetacean, and ray teeth from Bakersfield. Tomorrow I’ll glue them to the back board with epoxy and have a label created at the very bottom. FYI @digit @Malcolmt @caldigger @Kurt Komoda @SailingAlongToo @WhodamanHD
  13. Hey Hi Y'all, I have been searching some very fine (nano) matrix from Shark Tooth Hill. The matrix went through the window screen but not the "grease splatter" screen. I have not taken any pictures with My scope yet, but thought I would show a "teaser" to peak some interest... My finds so far. Largest pieces are about 1 millimeter.
  14. Shark Tooth Hill Thresher?

    This came from Ernst Quarries last year at slow curve. I don't think this is a hooked Mako because of the micro serration on both sides of the tooth, so what is it? I know I failed to include a scale but this tooth will just cover an American Quarter. Thanks in advance!
  15. Finally making some progress at our Slow Curve lot. My son pulled out the first meg! Also found a few nice hastalis and planus as well as a bird sacrum.
  16. Fall STH Trip

    Decided to take a day off while working in California. One of my coworkers was interested in going for a dig so we headed to Bakersfield. Met Rob at the gates at 7:30 and headed in. This was the first time I have had the time to spend an entire day. (Also the first time I have been there in under 100 degree temps.) Rob led us to Slow Curve and we began digging. Was a fun day. Found a few nice teeth and left with five gallon pickle bucket of matrix to look through back home in Dallas. Airport loves me when I check in 80 lbs. of dirt. Found a nice 2.1 inch hastalis which may not be big to some but was my best of the day. My favorite find though was my Aulophyseter morricei whale ear bone with associated stapes bone (Thank you @boesse for the identification.) Overall, we had a fun day and found some nice teeth. We were kept company by this furry little friend as well. Thanks for looking.
  17. Whale ear bone with stirrup??

    Went to Ernst quarries last week and found this whale ear bone. When I cleaned out the matrix this small bone popped out. My thoughts are that it might be a whale stirrup bone from the ear. If that is the case, what are the odds it is associated to the earbone found in the same matrix?
  18. Work has me in Sunnyvale CA but I have Sept 30/Oct 1 free to fossil hunt. I'm not bring dive gear but I'll bring a hammer & chisel if anyone has any suggestions. Trilobites or Shark teeth or similar. Thanks, Calvin
  19. Interesting Tooth From STH

    Hi Everybody, I found this tooth the other day and it looks different from all the other teeth I have found in the STH area. The tooth resembles (to me) a Isurus lower but it has clear cusps on both sides of the tooth. I looked on elasmo and I don't see anything that looks quite like it listed for Bakersfield. The only thing I saw that looked like it had cusps was a catshark but the root doesn't seem to match. Maybe a Isurus Retroflexus? I'm stumped please weigh in with ideas. (I will try for better pictures tonight) Thank! Jesse
  20. Trip to Shark Tooth Hill

    I went to the Ernst quarries at shark tooth hill last weekend and had a great time collecting teeth. I'm new to the area and hadn't collected there before, but I met a couple there who were very experienced and helped me identify a lot of what we found. I've attached a picture of what the landscape looked like as we were getting ready to leave. Really a beautiful area, in a desolate sort of way.
  21. I had to make a business trip to California and to the San Joaquin Valley this week. I planned for a partial day on Thursday to take some time for myself and do some hunting. After checking the weather, it was clear it was going to be a scorcher even for a Texan but I figured I would take my chances with the elements and book some time anyway. I got in contact with Rob at Ernst Quarries and arranged for a half day dig. We met at the gate at 8am. At first I thought I was at the wrong entrance since I was the only one there. Rob pulled up and told me there was a possibility I could be the only one there for the day. After waiting several minutes we headed up the road and made the turn towards the Slow Curve area. Rob was kind enough to show me around. There were plenty of tools and sifters available as well as hammers and chisels to break through the different layers. He warned me to watch for snakes and and call him if I needed anything. They had spotted a small rattler the day before in the same area but I was pretty certain the snakes are smarter than me and were not going to expose themselves to the 96 degree weather that I was about to subject myself to. I started in an area where two Meg's were found the week before. It was my first time chiseling into the bone bed and was not really sure what I was doing at first. I found a couple of small teeth and of course broke the root on the first not heeding warnings not to clean in the field which was a temptation I thought I had gotten out of my system on my last visit. I found a small piece of Meg, a fragledon or in this case a specladon. It got my juices flowing but that was the closest I was coming to a Meg for the day. The heat was harsh. I was hydrating almost as much as I was digging. I split my day up by chilling a while then sifting a while then when I got too hot, checking the surface while drinking water and wishing that I could have come on Friday when the temperature was a forecasted 75 degrees after a front. None the less I kept going until about 1:00 when I had to head to LAX for a 6:30 flight back to DFW. I left with a handful of nice teeth as my reward for the day. A few new firsts for my collection including my tiny frag of a Meg, a first hemi, and a partial cow shark. I love how it keeps producing enough to keep me happy but leaves me also already dreaming about the next trip and hitting the honey hole. Here are some pics of some of my finds. Thank you for looking.
  22. Finally! Shark Tooth Hill

    Well the stars aligned or maybe it was really just my schedule but I finally had the opportunity to do a short trip to the Ernst Quarries and hunt for some of those great Miocene makos I have seen on other posts here on the forum. I had to be in Bakersfield for work last week and went on the website for Ernst Quarries and saw that they were closed on the one day I would be available to hunt so though a little dissapointed I decided I could at the very least check out the Buena Vista Museum of Science and Natural History during my spare time. I looked up their website to see when they were open and to find out the specifics and low and behold, they were having a dig on the very day I would be in town. I reached out to them and found out they would be out there for three days and I asked if there were any openings for a half day dig that I might be able to join before heading out to Fresno for my red eye back to DFW. Koral at the museum was very accommodating and told me they did indeed have an opening for Friday morning. I filled out all the necessary paperwork and sent it back. Koral was great about getting me all the information I needed about the hunt and what I would need to bring and what they would be able to provide. Which wasn't much since they really do provide you with everything except water, and sunscreen. I arrived at the museum at 6:30 for my 7am orientation. I could have been there at 3am since I hardly slept the night before from all of the excitement. After some more paper work and paying my membership to the museum and fee for the hunt, I spent about 20 minutes looking at all of the exciting items they have on display at the museum. At 7 am sharp, Chuck our host for the hunt started the orientation and gave us all of the details and safety notes for the trip then we carivanned the 30 minutes to the quarry.
  23. Shark Denticles

    In a recent post about denticles (here), it was mentioned that most of the dermal denticles we find are usually from rays, and not sharks. Ray denticles are much larger than most shark denticles, especially the big sharp thorns common on some rays. I was determined to finally find a few nice shark denticles for my collection - I've already got plenty of ray denticles, but I had never found any from Cenozoic sharks (I have a few tiny Paleozoic denticles, but those are much different looking). Shark Tooth Hill is a site near Bakersfield, California. It is Middle Miocene in age. I had some left over microfossil matrix that I had searched already. I'm glad I saved it! I poured out the silt and tiny pebbles from the bottom of the bag and put it into a small vial. I filled it with some water, shook it up, and poured out the finest silt and water. I repeated this process until only the sand and tiny grains of gravel were left at the bottom. I let it dry overnight, and today I searched a little under my microscope. I was surprised to find a few very small fish teeth (most were less than 1 mm long), and I also think I found my first shark denticles from this site! I was experimenting with a cheap new digital microscope to get these photos - the camera on the microscope doesn't have the greatest resolution and can only seem to capture small images, so I combined four views of each denticle for these pictures.
  24. Recently back from my trip to the San Francisco Bay Area (San Carlos, CA) to visit with my wife's sister's family. The purpose for heading over from South Florida at this time of year was the opportunity to photograph Elephant Seals at their breeding colony at Año Nuevo State Park--which we did and I'll post photos in elsewhere on TFF. I had been reading a lot about Shark Tooth Hill on the forum and considered a side trip to go check this locality out while in California. After a little research online I found that Bakersfield, CA (where the Ernst Quarry is located) is only a 4 hour drive down I-5 through the San Joaquin Valley in central California. We planned on renting a car and charging up the iPod for a road trip listening to an accumulated cache of podcasts during the 8-hour round trip. Instead, we chose a more interesting alternative. My wife's sister and her husband both worked for one of the dot-com startups in the 1990's that actually worked out. As a result they were able to retire early, build their dream home in San Carlos, and buy a few toys to amuse themselves. My brother-in-law Bob had been interested in aviation and had his pilot's license for some time. Eight years ago was able to upgrade his ride to an Eclipse 500 personal jet. Money can't buy you happiness but it can get you some fun toys. Bob is always looking for a good excuse to take the plane out and so he offered to fly us to Bakersfield. This condensed the 4-hour road trip into a 40 minute transit at 17,500 feet. We arranged for a rental car to be available at the JetCenter when we arrived and, for the day at least, we were living the jet-set rock-star lifestyle. I guess true rock stars would have been picked up in a chauffeur-driven limo instead of driving off in an SUV and probably wouldn't have stayed at the Holiday Inn and had dinner at an inexpensive Mexican restaurant. But that's okay since I'm more of a rock hound than a rock star anyway. We took out some of the seats in the back of the plane and secured three 5-gallon buckets to the floor with straps to verify that we'd be able to carry back some matrix from Shark Tooth Hill. Tammy sat in the remaining seat in the back and I got to ride shotgun (co-pilot).
