  1. I've heard there are whale bones and petrified wood found in beaches in Santa Barbara, are there any specific sites that yield these specimens?
  2. I am new to fossils... I found this on the rocky shore of Cabrillo Beach, San Pedro, California. The rock is a hard sandstone. Any idea about the fossils?
  3. Went fossil collecting in Bakersfield Round mountain silt formation this weekend and found an unusual tooth. I think it belongs to a mako shark (isurus planus), but it is unlike any other shark tooth I have ever found from the locality. The root is damaged, but it is more than twice as thick as any other hook mako I have ever found. Never seen a shark tooth this thick. Any ideas on the identity of this tooth? Thanks in advance for the help.
  4. OK, I finally took a camera with me on this one. For the past year, I have visited an area about an hour south of me that is a source for Great White teeth and other marine animal parts. But for the most part, GW teeth is the majority of what is found. Now the location is perched on a steep hillside about 7 miles inland of the Pacific Ocean. It was a deposit that had been cut through by a river and re-deposited in a different location, much like many of the sites along the east coast are now. However, the redeposition was done a very long time ago. It is found about 200 feet above the valley floor and goes up at an angle due to faulting (what else would you expect in California, the land of earthquakes?) The formation consists of what I can easily call cemented gravel (heavy emphasis on the cement part!) I only have a hand pick and a trench trowel (folding shovel) to somehow work my way through that "rock". It doesn't take long swinging a pick with one hand to wear you out. By the end of the day, My arm feels like limp spaghetti. Because this ground is so hard and worked by river action, finding a whole tooth with roots intact is something of a rarity. Mostly you will find shards of crown enamel or the teeth are so worn they have no serrations at all. I had worked a hole for a while only to figure out the actual deposit was about 12" below the floor of my pit. Did I mention the deposit goes up at an angle? Missed it!!!! OH MAN! I had to backtrack removing my tailing pile and having to re dig the hole to a lower level. Did I mention the humidity was about 105%? I was completely drenched in sweat. Nobody said fossil hunting was easy work!!!! The first photos are the small hole I had to dig to establish the fossil layer once the tailings were removed. Believe me that ground is much harder than it looks. Guess I can skip the gym this week! Last photo is the day's tally. All Great Whites except for a small Cow Shark tooth. The top tooth on the left is 2 1/8" there is a small tooth in matrix at the bottom (note there is no root). I was lucky enough to get three with whole roots this trip. Thank you for putting up with my rabbling. Doren/ caldigger

  7. First off, I want to thank Doren for sending me a small flat rate box full of STH matrix for me to try sifting through. I still have quite a bit of fine matrix to sort through but already I've managed to find hundreds of specimens. I've found quite a few Carcharhinus, Cetorhinus, Galeorhinus, Squalus, and tons of ray teeth. When I'm finished with all the matrix, I think I'll write a follow-up post with all the nice specimens I found. I'm having a little trouble identifying various species of rays - maybe someone has a literature suggestion to help me get familiar with different tooth characteristics? From what I can tell from other posts, the features that differentiate some ray species are quite subtle and to my untrained eye, very difficult to distinguish. I wouldn't mind some ID help with these teeth in particular. Scale to the right is in mm. If you could also comment on how common/uncommon these species are and what position they are in the jaw that would be immensely helpful as well. Also, maybe someone wouldn't mind making a list of the species found at STH and rank how common they are? Also, does anyone have suggestions for removing the last bit of silt/sand from the crevices in the teeth? I've tried water and gently stirring but that does not have much of an effect. Thanks for your help!
  8. A duck-bill dinosaur, Augustynolophus morrisi:
  9. Hello, I recently found this object washed up on a beach in northern California. We're wondering if anyone recognizes it, or could tell us what type of animal it might be from? Thanks so much for any suggestions, Jackie Sones Bodega Bay, CA
  10. Hi, I found this nice shark tooth at the Ernst Quarries in the Slow Curve. Not really sure about the identification, but it looks like a mako to me. The tooth is 2 inches long. Thanks.
  11. Took all of my best of the last three years and laid them out last night. Thought I would share.

  13. This online GoogleMap of California fossil sites may help anyone looking for new sites. It lets you search your own location so you can see which places are closest to you and how far. Additionally, there are links on the locations to articles that tell you about its geology, fossils, and directions. Hope it helps, please reply with any feedback or suggestions to improve it.
  14. Does anyone know what this is
  15. Hello! I am not really a fossil collector- or any kind of expert- but I do like to collect natural things I find in various places, and have held on to these for a few years without having an idea if they're really anything at all. I found this forum and would absolutely love some help! Even if there is no identification to be had, it would be great to know if it's still worth holding onto- or... just a rock. The first is a white hard substance with some interesting spiral patterns in it. As you can see in the first photo, the inside chamber of the main form is hollow. I found it on a California beach, probably Pismo?
  16. Greetings everyone! I am a long time follower of this site. This is my first posting. Thanks ahead of time for any assistance in identifying the following. I recently found a fossilized bone and what looks like a fossilized organ or concretion. I am usually pretty good about recognizing a concretion when I see one. However, this one looks a lot different from the concretions I normally come across in the area. They were both found within several feet of each other in an alluvium/terrace deposit. R. Squires describes the alluvium as "nonmarine, Holocene, last 10,000 years" and the terrace deposit as "nonmarine, upper Pleistocene, 50,000 to 10,000 years." The location is immediately adjacent to the Santa Susana Formation (marine, upper Paleocene to lower Eocene, 54 to 50 million years) and the Simi Conglomerate (nonmarine to marine, lower Paleocene, 65 million years). There are several other formations in the general vicinity of this location. I have several pictures of both (see below). The first set (F1) are of the bone, the second set (F2) is of the possible organ/concretion.
  17. 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!
  18. The tooth that started it all, found while looking for rocks in the Santa Monica mountains. I just looked down and wow nice great white. At first I thought someone dropped it as why would there be a big shark tooth on the side of a mountain. Turns out I got lucky and found a great fossil. I have looked a bunch more and not found anything else in the area, it is still the largest tooth in my collection! Thanks for looking
  19. Does anyone know if this is a fossil, and if so what it might be? Thanks! -Jason
  20. Hi all, we found this at the beach today - doesn't look like a marine mammal, and my guess is recent storm run off brought it down a creek. Any idea if it is a fossil or just a bone? Seems like a cow/bison cervical vertebrae, perhaps.
  21. Hi all OK, this is an interesting one. Attached are images of the Sandollar that was found on the California coast. It is broken, but I'm curious if it is fossilized.It is extremely hard, and feels like stone. I have many Sandollar's that are extremely fragile, however this one is heavy, lacks all the brittleness that one would find in a newer Sandollar. What are the signs to look for if fossilized? I took the best pictures that I could, hope they will work. thx
  22. From the album Untitled Album

    This is just a small piece/edge of a layer that must have encompassed acres. It was a horizontal layer extending into the base of a 50 foot vertical cliff, and so, very difficult for me to recover even this small plate this is a type of sardine---Xyne grex
  23. Hi all I search the species of these urchins. Thank you for your help!
  24. Ancient beasts roamed this secret spot in Death Valley Washington Post, Dcember 2, 2016 Death Valley's 'secret' fossil canyon could finally be opened to the public after being hidden for almost a century 1. Remote fossil hotbed covers an area of around five sq miles (12.9 sq km) 2. The area was closed to the public in 1940 to preserve the cache of tracks 3. The US National Park Service, which is celebrating its centennial year, has been called on to open up the forbidden area to visitors Death Valley's hidden fossil canyon slowly opens to public San FranciscoGate, November 17, 2016 Yours, Paul H.
  25. I found this bone in lake limestone near the late Miocene Moraga Formation east of San Francisco. Animals fossils in the area include, horses, hippos, antelopes, mastodons. Any idea what part of the anatomy this is: knee, vert? What animal? Dimensions 8cm x 8cm x 5cm high. Pictures of other bones have been IDed as possible camel leg bones. Four photos taken while the top is being rotated toward me. First photo is front. Second is top. Third is back and fourth is bottom. Thanks, John
