  1. Well I was bored and started looking at a box of bones and such scraps that I had brought back from my last trip to Sharktooth Hill in California last Summer (I tend to collect just about everything that looks like something from the sifter). As I was scrutinizing what's what, I discovered two pieces fit together and Shazam, an Allodesmus tooth!!! I quickly glued it back together and now have a nice piece. Lesson learned: it sometimes pays to revisit your finds with a fresh pair of eyes.
  2. My wife and I worked the Slow Curve location at Ernst Quarries (Sharktooth Hill, Bakersfield, California) this past weekend and collected an exceptional C. hastalis from the bone bed. This is a very large lower tooth that measures 3.25" and is in pristine condition. I saw a post recently about Sharktooth Hill mentioning the road to East quarry was closed due to recent rain damage and questioning whether the Slow Curve location (the only location still open) is still productive. I can assure everyone it is a productive location to dig for middle Miocene marine fossils. In addition to this large hastalis, other uncommon prizes from the weekend included a complete lower Hexancus andersoni (sixgill shark), a pair of Allodesmus kernesis teeth (primitive sea lion), and an excellent Aulophyseter morricei tooth (pygmy sperm whale). Each day of digging will produce many of the species and sizes more common to the locale to complement any of the uncommon prizes you are lucky enough to find. If you happen to be near Bakersfield, CA and can afford the time, put this on your list of sites to visit and collect. It will be worth your time - just plan your trip before, or after, the brutal summer heat settles in. I am undecided as to whether I should remove this once in a lifetime lower hastalis from the matrix, or preserve the piece in the matrix as is. I'm curious about other collector's preference regarding the matrix - remove? OR intact?
  3. Hello all! Well, I've done an initial search of the Sharktooth Hill matrix that @ynot sent me this week, and I'd like some help identifying some of the larger shark teeth - please and thank you! I think I'm right about the first three but I'm not so sure about the fourth since the root is worn down or covered by matrix, so it doesn't look exactly like the others - thoughts? I'm pretty sure about the one on the right but less sure about the one on the left - I did lump them together, though, since they both have a pretty obviously serrated shoulders. (By the way - I considered that the one on the left might be Sphyrna sp. (hammerhead), but I can't see a deep nutrient groove in the root.) Thoughts and opinions are much appreciated! I think this bunch of teeth just might be my favourite because of all the beautiful colours!!! Am I right about their identity, or should they be labelled as something else? None appear to have serrations, by the way. I doubt that I'm right about these ones since Isurus oxyrinchus (and I. retroflexus, the longfin mako) are not common for Sharktooth Hill, but I don't really know what else to suggest - please help! None of them have serrations, by the way. And finally (for now), a couple of tiny little teeth: Thanks so much for your help!!! Monica
  4. Hey hi Folks, I was wanting to see if I could get a better idea of the identity of these teeth. scale is in inches. They have a faint carinae (cutting edge) that has weak serrations at the lower part of the edge.This feature is on the inside of the curve of the tooth, but not centered. It is more apparent on the darker crown. The darker tooth also has a second serrated carinae that splits at the base (forming an upside down "Y") Thanks for Y'All's knowledge and help. Ynot
  5. Hello once again! Well, March Break has finally begun, so my daughter Viola and I decided to spend some time sorting through the Sharktooth Hill micromatrix that Ken (@digit) sent me as part of the "rolling auction" lot that I won last month. Here are some pictures of a few of the finds so far... Ray teeth? - different from the usual plates that I've seen before Cow shark (Notorynchus sp.)? Dogshark (Squalus sp.)? Marine mammal teeth? Any ideas? Cute little shark teeth in matrix - any ideas re: their identity? ??? ??? I'll post pictures of more items on another day, when my eyes have stopped burning Thanks in advance for your help! Monica
  6. Hey guys, I've been off the radar for awhile .. work you know .. been working on Siggraph for those of you who are familiar with software development. Just wanted to start a new topic here .. This one is right at 3.00" - 7.62cm C. carcharias Bahia Inglesa Formation South of Caldera Provincia Copiapo III Regio de Atacama Chile
  7. Hi all, I recently went to Sharktooth Hill and collected a few bones and plenty of teeth. Wondering if there are bite marks on this small bone. There are three deep grooves on the bone which I suspect are bite marks. May be wrong though.
  8. Allodesmus kernensis mandible with canine and 2 post canine teeth. There is also an upper incisor from an Allodesmus kernensis and a cetacean vertebra in matrix.
  9. From the album Fossils found by ynoT at Shark Tooth Hill California

    Allodesmus sp. mandible with an upper incisor and a cetacean vertebra from the round mountain silt.
  10. Picture is of my find of teeth from STH area of Bakersfield CA. All found with a few hours of digging. Not a bad day!
  11. Hey hi Folks, I was cleaning this Galeocerdo sp. in matrix piece from Sharktooth hill (area)... And found this little thing on the other side of the bone fragment... It is just over 1/4 inch. The damage was pre burial. I think it had a cusp on both sides. I can not see any serrations at x10 magnification. Any ideas of what it is? Thanks Y'All, Tony
  12. Hey Hi again, Here is another oddity that has shown up in the buckets of stuff I collected at Sharktooth hill. Not sure when it was found or which site on the Ernst quarries it was found at. I know it is a manganese concreation, but it has an unusual amount of bone pieces and a fish tooth mixed in on the surface and the sape is atypical of the other pieces of manganese that I have seen there. I was thinking it is a manganese replacement of a fish excrement. What do Y'All think? scale is an inch ruler. Thank Y'All!! Tony
  13. I recently won an Auction that was started by Tony (YNOT) and it included a Medium box of Sharktooth Hill micro matrix. The below pics, along with specimen counts, are examples of some of the items that I found in this matrix. (+80) Cetorhinus (Basking Shark) (+300) Myliobatis mouth plates
  14. Booked a morning at Ernst Quarries since I had some work in Bakersfield this week. Thought I would show what little I found. Not the most productive three hours but any day digging in dirt is better than working. The weather was unbelievable as well.
  15. Hey hi Y'All, Every year the rock club that I belong to puts displays in the local library to advertise their upcoming show. This year We are hosting the California federation for a 3 day show (a month earlier than usual.), September 16, 17 and 18, 2016 in Placerville. The club has put displays up in August (The club will also have displays up in September.) One of the August displays was set up by Me, with some of My Sharktooth Hill finds. Here is a picture of the display... I will post closer views if anyone is interested. Enjoy! Tony
  16. Hey Hi Folks, I Found this bone at Sharktooth hill this spring. It has been hiding in one of the buckets of matrix that I collected. Is it a Sea Lion femur? Is it possible to tell which critter it came from? Thanks for the help!! Tony More pictures coming...
  17. I have been cleaning the matrix pieces that I have found at Sharktooth Hill. Thought that Y'All might like to see one from start to finish. I chose a pathologic Cosmopolitodus (Isurus) planus. Here are front and back pictures as found... Five minutes later...another tooth appears. Five minutes later an unseen crack removes most of the excess matrix and another tooth appears (Fish this time.).. More....
  18. Hello TFF members, The family and I decided to book a trip to Las Vegas the week of March 21. I have to admit, part of the decision was due to the fact Sharktooth Hill was only a ~ 4 hour drive away. I had looked at the Ernst Quarry website and noted Slow Curve was open Tues-Thurs that week. I sent an email to Rob (quarry website) right after booking the trip, as I have wanted to get out there for many years now. I have not heard back yet, but I also left a voicemail and it stated it might take 7 days for a response. I'm looking to drive over either Wed. March 23 or Thurs. March 24, depending on the weather. I know this is short notice and during the week, but if anybody is interested in meeting up at the Quarry, I would enjoy having some company to dig and talk to on the adventure (family is staying in Vegas with friends, so I'm making the trip alone). Jay
