  1. I wanted to ask if any fossils have been found in Coastal Canyon Park in Newport Coast, California, because most of the sediments in Orange County are Cenozoic in age (for example, the fossil otariid Eotaria and the fossil walruses Gomphotaria pugnax and Titanotaria orangensis have been found in the Miocene of Orange County).
  2. Unknown fossil/or trace

    I did not collect this. Found in a box of miscellaneous fossils at a rock show.
  3. Took this photo of an unnamed eschrichtiid from the Pliocene San Diego Formation of San Diego County in March 2019. Until the 2000s, the fossil record of gray whales was confined to the Pleistocene, but thanks to the work of Michelangelo Bisconti, it is apparent that gray whales emerged about the same time as the oldest rorquals (Eschrichtioides was long considered a balaenopterid, but eventually recognized as a gray whale relative).
  4. The balaenid specimen SDNHM 43880 I photographed at the San Diego Natural History Museum in December 2017 was once referred to Balaenula, but Churchill et al. (2012) recovered it as sister to the bowhead whale rather the right whales and Balaenula, and recent erection of Archaeobalaena dosanko for the one balaenid specimen from Japan previously referred to Balaenula makes clear that the previous referral of SDNHM 43880 was untenable. However, it is unclear whether SDNHM 43880 is a new genus and species or alternatively a new Balaena species due to the cladistic position of SDNHM 43880 obtained by Churchill et al. (2012). Churchill, M., Berta, A. and Deméré, T. (2012), The systematics of right whales (Mysticeti: Balaenidae). Marine Mammal Science, 28: 497-521. doi:10.1111/j.1748-7692.2011.00504.x
  5. Tooth or Rock

    Hi all, just found this on the beach in San Clemente, California, USA. I assume it’s a rock, but the bottom shape is so toothy, I wanted to check. It’s 4 inches long by about 2 inches wide. I included photos of the front back and side. Any help is appreciated, thank you!
  6. I found this sticking out of the dirt on a hiking trail in southern California, Palos Verdes area. It was on a hill where there are a lot of rocks and I have found some other fossils in the general area (mostly just small plant fossils and a couple of tiny fish fossils). I am trying to figure out what it is. The top is domed, like a half cynlinder, and it has a hole in the middle. The length is about 3 inches. The hole is exactly 1 cm and perfectly round. There is a lighter color to the outside compared with the core (see photo that shows in interior edges of the hole) leading me to think it might be a fossilized bone. One end has a scoop in it that looks like another hole, but is very shallow. The bottom looks more like a regular rock. I read that one way to identify a fossil compared to a rock is to touch your tongue to it. It sticks to the tongue, as would be expected from a fossil. I am thinking it might be a branch with an insect burrow hole in it, or a bone which had a hole carved into it. The hole goes about half an inch in and then stops.
  7. Hi all - in the hopes of attempting to reach a wider audience, and anyone who has collected possible sea otter fossils, I'm sharing the first two posts from my blog "The Coastal Paleontologist" in a short series on sea otter paleontology and evolution. The first one is mostly a bit on sea otter biology, and the second is the first one that really deals with the paleontology aspect. The third (and fourth?) posts will deal with what the limited fossil record can tell us about sea otter evolution. The sea otter fossil record is quite poor, and I'm hoping that some of you may have found some fossil specimens and might consider making them available for scientific study. Anyway, here's part 1: https://coastalpaleo.blogspot.com/2020/05/the-terrible-fossil-record-of-sea.html And part 2: http://coastalpaleo.blogspot.com/2020/06/the-terrible-fossil-record-of-sea.html Part 3: will update as soon as I get it finished! And a teaser - the left mandible of the holotype specimen of Enhydra macrodonta from the Crannell Junction locality right off of Highway 101 near Arcata, California. I spent about 3 years emailing various curators about this fossil, if they had it on loan, and I finally got a response from Dr. William Miller III at Humboldt State University in Arcata that he didn't remember such a specimen existing there. The paleontologist who named it, Dr. Frank Kilmer, who was retired, mailed me a letter indicating that the mandibles had been given back to the private collector (!!!) after the species was published - but nobody at HSU knew their name! One former student did, but would not return my phone calls. I visited HSU in 2008 when I was an undergraduate student and rifled through their teaching collection and found A mandible, but I didn't think it was THE mandible, because of Kilmer's letter, and a misplaced label suggesting it was from a different locality (and therefore a duplicate specimen rather than the original). Dr. Miller indicated I should arrange for the fossils to be transferred to a larger museum, as he was certain that the collection would be thrown in the garbage after he retired! I visited again two years later and set aside all the specimens that should be transferred and secured an agreement from HSU for the material to be transferred to UC Berkeley, which finally happened about five years later. I did not realize that this mandible was in fact THE mandible, or at least half of the holotype (the right mandible is still missing, presumably in that private collection) until I was able to download a much, much higher quality scan of the photographic plates in Kilmer's 1972 paper, and I was able to match barnacle scars between the published image and the fossil. So, we may not have the more complete of the two mandibles, but at least we have one of them, and it is my hope that there is more material in private collections and that more can be discovered in the future.
  8. Piece of ?Mammal? Bone from Southern California

    I’ve received a chunk of what I believe to be a marine mammal bone from a diatomite mine in the Monterey Formation in Southern California. It is from the late Miocene but I’m not sure what mammal or what bone it is. I know this is a long shot as there isn’t much to go off of but anybody have a clue?
  9. Fossil ID - help with shell fossil

    Hi, I would really like some help to ID this fossil shell. Is it a brachiopod ? What time would this be from? I found this in the quicksilver almaden county park in California. There were quite a few similar shell fossils, Parts of them are visible in this piece of rock itself. Thanks a lot !
  10. Porpoise / Dolphin Bone?

    Is this bone from a porpoise or dolphin? it came from Palo’s verdes California and was found on the beach there. If so any idea on the age?
  11. Worm Borings?

    Hey everyone just wanted to check in with you all and see how you are doing. I also wanted to inquire about these Worm Borings/Concretions, and what our members consensus might be. Maybe our resident concretion collector @Ruger9a would be able to help me out. Anyway, here are the pictures: Here is a photo of the excavation site:
  12. Please help ID this

    Hello everyone. My husband and I found this today while combing the creek bed of the Escondido Creek located in Encinitas, California, USA. We believe it is a tooth. It looks quite old, however I am not sure whether it is fossilized. We are not fossil hunters or collectors, just everyday amateurs who stumbled upon this find. Any help identifying it would be greatly appreciated, thank you!
  13. Please help identify

    Ok these are more pics of the rock I posted already and was confirmed by this forum that it indeed does look like one. I'm focusing more on the mouth, jaw, and facial structure. The nasal cavity. In Hope's of possibly identifying what type of animal this actually is. Thanks for your help.
  14. Strange oddity possible fossil ?

    This one is crazy. After research it looks like the shape of a little embryo. Its white lifted off the rock and it has a while almost looks like a umbilical cord or vein. it's so strange
  15. Sth stuff (:

    Hi guys been going through some matrix and found some oddballs wondering if anyone could help, thanks 1.looks crocish? 2.looks almost like a worn pufferfish mouthplate? No idea though 3. Not really an oddball but wanted to show the wonderful purple colour 4 some kind of fish tooth?
  16. I searched every body of water on Rockd to see any sedimentary deposits that are near me; there is nothing. Everything is metamorphic, but then I came across Lytle Creek. I wen't on the map on Rockd and checked and it said something about sediment deposits. The info was too confusing; I couldn't find any easier info.
  17. Bone Skull Identification

    Hi there! I'm hoping you can help me narrow down what animal this skull might be. Most likely from the California area. Thanks in advance!
  18. Potential concretion?

    Found this at a undisclosed spot near Ventura, also found a large fossil shell deposit potentially from Pliocene. Will post pictures if people want me to. Btw if you have any clue or want pics of the other side of this please comment!
  19. Shale ID?

    Hey all! I got out today to hang out on the beach and ended up searching a shale scree not far from where I parked in santa barbara, CA. This looked like it had fossiliferous potential so I grabbed it along with a good amount of nice malachite. A tube-like shape with white crystal-like openings which measures about an inch in this piece of shale. Curious to se what you think and thanks as always!
  20. Santa Cruz Mountain Miocene Era Fossil #1

    I collect fossils in already disturbed areas around Scotts Valley, CA, mostly sand quarries and road cuts. The fossilized sand dollars I've collected date to the Miocene 10-12 million and, from what I understand, most everything is similar from a chronological point of view. This area was a vast, shallow ocean back then so most of the fossils are aquatic. An intact sea cow from this era was famously collected in this region. Thanks in advance for any help you can give me!
  21. New member;ID Request

    Hello new member here, my name is Robert! I found this site while searching google in an attempt to identify some beautiful items I came across recently while at the beach in san francisco. I understand most of you guys refer to yourself as amateurs, though reading a few forum topics before creating my account I was impressed with the amount of detailed information in regards to your studies and findings. That being said I must admit I am %110 amateur in my knowledge of fossils, different time periods, etc. So please forgive me if I seem to ask simple questions like I don't know what I am talking about, I am still learning. WELL, in regards to the piece I am hoping to learn about (please see attached image). I recently found it while I was at the beach in San Francisco area. It measures 2 and 3/4 inches wide, 2 inches tall, with a shallow depth of a 1/4 inch. My main question is...WHAT is it!? I've seen many sand dollar fossils, coral rock fossils, clam fossils recently on the beaches here, but I've only seen one like this. The milky white crescent shaped object that is offset to the right of the center of the stone, looks like a tiny shrimp or something (again , please forgive my lack of knowledge). Also, the only thing I can relate the slightly irridecesent dark blue-ish streaks to are the inside of some of the mussel shells that I see on the beaches here, so maybe it is in relation to that...? Again, I have no idea but I do speculate much as I've recently grew heavy in interest on the subject and those alike. It would be greatly appreciated if anyone has some pointers on or can possibly identify this, what I believe to be, fossil stone of some sort. I have many photos of all the beautiful items I've recently collected, and needless to say, so many questions I wish to ask you all in regards to them. I am planning to post detailed images of them all in the My collections section but for some reason most of my pictures on my phone exceed the "Max total size of 3.95MB" in the image upload section so I am going to try and take some different pics that are "uploadable". I would be more than happy to take new pics or zoom in closer on any specific area(s), if needed or necessary. Thank you all for your time
  22. Hey everyone! I have a couple recent finds that I would appreciate your input on. I’m currently unsure of the formation that these fossils come from. I found this outcrop underneath a parking lot. It’s orange conglomeratic sandstones which makes me think Hookton Formation which would place it somewhere around 450,000 ybp. Scale is in inches.
  23. Hey everyone! This will be my first attempt at a trade in the TFF. Im offering a variety of fossils from the Price Creek Formation of Humboldt County, Northern California. This formation has been dated to late Miocene early Pliocene. As far as to what I’m looking for in this trade, I love all things Mollusca! Gastropods, Bivalves, Ammonites, Belemnites or Brachiopods, I’ll take them all. Invertebrates of any kind will strike my fancy though. The weirder the better. I’ve seen some Ram’s Horn Oysters that are awesome! I have no qualms about trading for these as a whole set, however shipping would be cheaper. I’m willing to ship anywhere in the United States, if your international I’m afraid that you’ll have to absorb that cost. I really appreciate all the knowledge that members have been forthcoming with sharing. Please pm me if your interested. -Nick
  24. Hey everyone! I’m starting this post as a continuation of this post: http://www.thefossilforum.com/index.php?/topic/102463-virtual-fossil-hunting-field-trip/ I’ve decided to start this new thread in prefer to better conform to the sites organizational structure and to serves as a more permanent home for my future adventures. So, if you haven’t already seen it, in encourage you to read it in order to catch up. In light of our current events I’ve decided to practice some self quarantine at my favorite fossil hunting location. The rocks here, the Rio Dell formation, represent an eastward trending embayment from the Pleistocene, overlain by orange conglomeratic sandstones called the Carlotta Formation, indicating and delta environment that fed into said bay. These have all been uplifted by the numerous and complex fault systems that Northern California is famous for. This site is easily accessible via a trailhead about 350ft above the beach.
