Kern County vs. Florida - The Hunt for the Elusive Meg
ruffalo posted a topic in Fossil Hunting Trips
While the Megalodon tooth seems to exist as THE find for many fossil hunters and/or amateur marine paleontologists alike (and rightly so!) it's never been my own personal "holy grail." However. My partner, who graciously tags along and searches with me whenever I drag him out on hunts often hours (or even days) of driving away, is absolutely enamored by the idea of finding one of these guys. I've heard many good things about Ernst Quarries/Sharktooth Hill and the private land surrounding it in Kern County, but I've also heard incredible things about Florida creek hunting - mostly Peace River and some, unfortunately, Top-Secret spots. We luckily have the opportunity right now to go on one (or both if we play our (credit) cards right) of these trips and was hoping those more experienced in the culture of "Meg Madness" would be able to provide any advice, pointers, opinions, comments, concerns, etc.?- 5 replies

Looking for stomatopod (mantis shrimp) fossils from Shark Tooth Hill
digit posted a topic in General Fossil Discussion
At the moment I happen to be picking through some micro-matrix fines from Shark Tooth Hill that @ynot graciously sent to me some time ago. All sorts of interesting micro-chondrichthyan fossils are plentiful in the really fine matrix (2 mm down to 0.5 mm). I'm also finding bits of the dactyl claws of stomatopods (mantis shrimps). There are two main types of mantis shrimps--the smashers and the slashers. The smashers have front claws ending in a hardened rounded "hammer" that they use to smash through the exoskeletons of crustaceans and mollusks (with the force of a .22 caliber bullet). The slasher types hide in burrows and wait for prey (mainly fishes) to swim overhead. They dart out of their burrows and with a very praying mantis style motion impale their prey upon these spiny dactyl claws. We also find both dactyl claw parts and the rounded ends of the smasher's "hammers" at sites in Florida and this has Roger Portell at the FLMNH interested in fossil stomatopods. I recently let him know that while I haven't yet found any "hammers" in the STH matrix, I have found smaller fragments of the slashing dactyl claws which are turning up in my matrix picking. It would be really useful to have some specimens of larger fragments of these dactyl claws from STH for our research. I'm wondering if any member out there who has picked STH micro-matrix has noticed these stomatopod dactyl claw fragments and more importantly saved them with the rest of the diverse micro-fossils from this wondrous locality? If you have some stomatopod material from STH I'd love to hear about it. You can reply here or drop me a PM. Thanks in advance. Here are some images of really nice stomatopod dactyl bits from the Montbrook site as well as the more usual smaller fragments from Cookiecutter Creek. Also, a link to a great page about stomatopods and an image of the two types of claws to help you envision how these fit into the larger picture. Cheers. -Ken https://arthropoda.wordpress.com/2010/02/09/why-stomatopods-are-awesome-i-super-strength/-

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- 7 replies

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.

Hello everyone, I'm currently in California driving through many of the national parks, and other beautiful sites of the state. I saw that we may be driving through Bakersfield from Sequoia National Park while going towards the LA area and I was wondering if it would be worth paying a visit to the famous Shark tooth hill location, but immediately a few questions came up that I decided to ask here. First of all, does anyone know how accessible the site is? Does one have to walk far to reach it or is it pretty much accessible by car? I'm with my family who are unfortunately not very excited by fossils and if it's not that accessible they won't want to go. Additionally, what kind of equipment is needed? Since I came here from across the country I obviously don't have any gear with me. Do you need to actually dig, or is it possible to surface collect? And finally, I saw a few things online about valley fever, how big of a concern is this? If it's something you need to protect yourself from, what kind of mask would work? Thank you to everyone who looked, Misha

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.

Greetings all. I just took a quick trip to visit the area where caldigger lost his life one year ago today. It was a sad visit to his beloved "Meg Hill" Bakersfield, but it was a little "respecting" I had to do. I didn't do much prospecting, but did spend a few minutes checking tailing piles. One thing I found and took a picture of but didn't take home, is something that resembles some sort of shellfish fossil. Either that or it's just a concoidal fracture of a mineral that's present. I just figured I'd get some opinions. As I said, I left it in Bakersfield, but thought it somewhat image-worthy. Thanks for any input. Cheers.

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).

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.

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.

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.

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.

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.

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.

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.

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!
