  1. Bone or teeth?

    are these bones or teeth? they look similar to some Ive seen around. Found in Menlo Park, CA
  2. Antler?

    Found a bunch of petrified wood up in the California Sierra Nevada foothills around 8500 ft After going over them this is one of 2 that stuck out as different. It is 3 1/2" long with rounded edges. Any ideas what it is? Thanks in advance Harry
  3. Hey guys, I dont really know what this could be, maybe just rock, but the color, shape, texture made me think twice - specifically the curved smooth bottom, sharp sides that curve strangely and just the shape in general. At first glance i thought it looked like a meteorite because of the flow-line'esque texture it has in some parts and the bottom side was smooth with little holes with some thumb print 'ish indents, and its darn heavy. But then it also reminded me of some marine mammal and large reptile fossil bones I've seen on here while perusing so I thought I'd ask. Also because of some other things I have found, which I want to ask about as well but dont want to spam all at once. Actually I'll post two of the other things too Found in Menlo Park, California about ~12" inches in ground, maybe slightly deeper. Menlo Park is considered Pleistocene/Holocene alluvial but there have been cretaceous foraminifers found in the towns surrounding Menlo Park. And then there was the paleoparadoxia found during the excavation of the Stanford Linear Accelerator as well, which is about a mile away from me, and they are from the Miocene I believe. Also after reading the USGS geological map survey of my area it seems that theres out crops from every time period, mostly due to the gazillion faults in SF bay area. So Im not really sure what I'm living on. Anyways.. The second rock looks like it has a mouth and some teeth which I found interesting. The third looks like a shell on the one curved end, but also like a saurapelta armor plate I've seen in photos before. Appreciate any thoughts, and if it is rock, do you know what kind? Thanks for your time and feedback!
  4. Bone Identification Help

    Hey guys and gals, While this isn't a fossil, I was wondering, if any of you had the time, could you help me ID this bone, as many of you are good at that sort of thing and I am clueless. Found in Menlo Park, CA. Still doing yard work when I have time and I came across this. Thanks for your help in advance! Hope everyones having a good day.

  6. Shark tooth?

    Hi everyone, I’m new to this community but have always had an interest in fossils and artifacts. This week I was in So California for work and walked down to the beach one night and found this. It looked like a large shark tooth but it didn’t look like images online. I’ve seen Megalodon teeth before and this looks like a petrified version. If it’s just a rock, that’s okay too. Thanks in advance for your responses.
  7. Hi I recently joined this forum and I need help to identify what type of fish fossil. My dad gave it to me several years ago and don't really know much about it so can someone identify it
  8. Natlandite Fossil Stone

    I joined with the hopes that someone here may know more about Natlandite fossil stone. My wife inherited a polished three piece set and unfortunately there is very little information available about it online. Within the two articles I could find we have learned that "it was first discovered in 1954 in Los Angeles, Ca. by geologist Manley L. Natland, during a small dig he made in his offices backyard. He was given a rock brought up during soil testing for an annex to the old Atlantic Richfield Building at 6th and Flower streets. Natland estimated the fossil stone to be between 5 to 7 million years old and said that it was likely formed when an earthquake dislodged a great mass of sludge from the Los Feliz area (then the seashore) and moved it to the Arco site, where it solidified. He had it cut and polished, revealing shells of bivalves, gastropods and coral in a marble like material, but thought no more about it until 1969, after he had retired from Atlantic Richfield, now Arco. That year, he asked to examine the excavation site where the building and it's annex were being torn down to make way for Arco towers, now known as City National Plaza. What he found was an entire bed of the fossil stone that he had seen years earlier. Natland arranged to have 500 tons of it hauled away and eventually had the rock cut and shaped into tables and statuary. The rock is about as hard as quartz and it contains about 350 different species. It was also named the official gemstone of Los Angeles in 1981." I have spoken with a paleontologist here at our local museum of natural history and he stated that he believes that some record of the stones should be preserved in a museum, if that has not already happened. He gave me the contact information of a paleontologist at the Los Angeles County Museum of Natural History and suggested that I contact them, as they would be the most appropriate place to store such fossils. They are absolutely beautiful pieces and any info or suggestions will be greatly appreciated! Thank you so much for taking time to read my post. Brandon Massey
  9. Beach fossil (CA) ID

    Can this be identified? Found at Huntington Beach in California.
  10. Possible Ammonite Fossil?

    Hello, I am new to the site, but I am a life long lover of all things nature. I found this little guy on the coast of California, most likely in San Simeon but possibly 30 minutes south, at Moonstone Beach. I found him about a year ago in August. He looks to be 6 1/2 centimeters. To forewarn everyone, I have little knowledge of history in terms of time periods, and am largely unfamiliar with geology as well such as rock types. I will describe as best I can per your requests. Please bear with me while I attempt to learn! Anyways, here he is. I believe him to be an ammonite but he has no spiral. Maybe a squid? Not even sure he is classified as a fossil, haha... Finally, thank you all so much for any and all responses, my scientific curiousity greatly appreciates it! Sincerely, Tyler North
  11. Hi all, can anyone tell if this is a dolphin tooth, and what species it is? It's a gift from @JBMugu It comes from Sharktooth Hill of Bakerfield, California. Round Mountain Silt Member of the Temblor Formation. It measures 1.7 inches long. Could it be Kentriodon?
  12. Any Sites in San Diego?

    I'm at San Diego for this weekend, and I'd like to know if there are any good fossil sites around there. I understand that many fossils in San Diego have been covered up or destroyed due to land development. If anyone knows of a fossil site, please reply or PM me. I've heard that Pacific Beach has some fossilized shells at its shore, has anybody been there to confirm this? Thanks, Seann
  13. Is this barnacle fossilized?

    I found this some years back at Pescadero Beach in California. I don't know if it's fossilized but if it is I think it would be from the Tertiary. Any help much appreciated.
  14. Possible STH coprolite

    I found this earlier this year, can't figure out what it is. The more I look at it the more I think coprolite. Let me know what you think.
  15. While descending from the top of our hike up Mission Peak in Fremont, CA, a friend and I came across what we suspect is a fossilized vertebrae. After doing some quick research online, I came across the following excerpt: "Some 3 miles east of the low hills and lying in the Mission District is a much taller ridge, Mission Peak, 2517 feet above sea level. Millions of years before the Pleistocene, sediments that now compose the Mission Peak ridge were deposited by both marine and fresh waters. These sediments are now a rich source of marine fossils, many of them clams and snails. Also, remains of Desmostylus, a mammal with characteristics between those of a sea cow and a walrus, have been found among the remains of seashells. These fossils were buried under marine water during the late Miocene time, or about 12,000,000 years ago. The Miocene is one of seven epochs of the Cenozoic era." Source: http://cnhm.msnucleus.org/Pleistocene/FossilBearingSediments.html I failed to take a measurement, but as I recall this object was about the size of a lemon. Can anyone help confirm if this is a vertebrae or provide any additional information? Thanks for your help!
  16. Found these fossils

    These fossils, amoung a few other, have been sitting in my curio cabinet for decades. My parents were the first homeowners in a brand new subdivision in Mission Viejo in 1967. When the backyard was dug up for a sprinkler system, they found this pair, which look like an egg. They are not matching pieces, I don't believe. They are about 3 1/2 inches long.
  17. Is this a fossil?

    I found this while out for a hike, it was in the eroded runoff ditches on the trail. It has a symmetry that seems biological to me, but that could be wishful thinking. What do you think? Thanks
  18. Is this a rib bone?

    Hey guys! Found this on my property again. (Menlo Park, CA) I no longer assume anything haha but I think this is a bone, possibly a rib? It is slightly over 3 inches long, and 1 inch wide If it is, is there anyway to tell what it's from, or at least generally speaking? or how old it might be? Like within the past 100 years? ? I really have no idea about these things... As always thanks for your help and patience with a newb!
  19. The Lomita Marl Member of the San Pedro Formation is a well-known source for Middle Pleistocene marine fossils, and its beautifully preserved molluscan fauna has been treasured by fossil fanatics for decades. There are outcrops in the city of San Pedro, California, although many of the "classic" localities have been destroyed by urban development. It is well-exposed in the Lomita Quarry, located in the Palos Verdes Hills northwest of the city. It has been dated at 400,000 to 570,000 years ago, about equivalent to the Santa Barbara Formation, which occurs further north along the California coast near the city of the same name. The Lomita Marl is also an extremely rich source for microfossils, as ostracodes and forams are both very abundant and easy to extract from the matrix. Most taxa in these two groups are still extant off the southern coast of the state, but a significant proportion of the fauna appears to be extinct. (One must hedge here, as the ostracode fauna of the Pacific coast of the United States is not very well known; the forams are better documented.) A small sample of washed residues has given me the opportunity to begin study of this interesting fauna, and I hope to show some images of taxa from both groups on this blog. This first entry will look at four ostracode taxa, selected simply because they are relatively easy to identify. (Much of the ostracode fauna is known only in "open nomenclature", as in "Aurila sp. A", meaning that the species has not been recognized or is undescribed.) Bythocypris elongata Le Roy, 1943 is easy to recognize. It is common, and appears to be the only member of the genus to be found in the Lomita. It is a member of the family Bythocyprididae, which are smooth, and some would say "uninteresting" as a consequence. As is normal in the family, the anterior end of the valve is broader and a bit more inflated than the posterior end. The remaining three taxa are all members of the large family Hemicytheridae, a group with interesting surface ornamentation: Aurila driveri (Le Roy, 1943) is one of the several members of the genus to be found in the Lomita, and the only one (as far as I am concerned), that is easily recognizable. The high-arched dorsum and strong ventral flange place it in the large genus Aurila, and the prominent anterio-ventral teeth are characteristic only of this species. The caudal process is low on the posterior margin, and bears fine denticles. Australicythere californica (Hazel, 1962) is relatively large at roughly one millimeter in length, and is more elongate than most hemicytherids. There is no caudal process, but typically 3-4 large posterio-ventral teeth. The lower half of the anterior margin has some small denticles, rather worn on this specimen. The valve outline is quite distinctive for this species. Hemicythere hispida Le Roy, 1943 is probably the easiest ostracode from the Lomita to identify, and is quite abundant. This image does not do it justice, due to the lack of 3-D. Under a stereo microscope it looks almost "furry", as the entire valve surface is covered with round-ended tubercles. (The lack of 3-D here is due to the excess white matrix obscuring all but the ends of the tubercles.) This species also has a particularly prominent eye tubercle, seen here at the anterior edge of the dorsal margin -- under the microscope this tubercle appears somewhat shiny, rather like glass. (I had to sacrifice the shine to get decent illumination of the rest of the valve.) To make these images, the specimens were simply laid flat on the inside of the lid of a micromount box. Not very sophisticated, but it gives a nice black background -- at the expense of making the specimen a bit more difficult to illuminate evenly. And it's quick and simple........... That's it for this entry. I will try to illustrate some of the many forams to be found in the Lomita in a future blog entry.
  20. hey guys, I'm back and probably don't have a fossil again haha but one of these days I will! I was wondering if anyone could help me ID this. I have found many rocks that are a similar shape to this. it tends to be difficult for me to tell from online pictures/descriptions, mostly because I’ll see shale and be certain its shale, but then I’ll see a picture of basalt, a random dark colored limestone rock, piece of chert, or even a fossil sloth claw or fossil tooth and then just have no idea because it could be any of the five depending on what photo I’m looking at haha. This is actually a very common problem I am having when trying to identify many different rocks (or possibly fossils) as my interest in fossils, rocks, minerals, and geology has recently grown. Also if anyone has any recommendations for a good intro book on fossils or rocks/minerals I’d love to hear them!! Maybe something more informative/technical than average kids book but not too academic/jargon-heavy/scientific/dry like a research paper would be awesome! Sorry about the link, imgur doesn't limit my upload size and my new iPhones pictures are massive so I have to resize to less than 50% in order to attach here. hope that's ok. there are 3 different rocks in the album, they are labeled. Menlo Park, CA according to the USGS survey of the bay area, I live in the Holocene alluvial section, bordering the Pleistocene alluvial section if that helps at all? found doing yard/landscaping work. its about 5 inches long but that's not exact, I can measure if needed. thanks in advance for any help and input!! https://imgur.com/a/IplRv
  21. Hi everybody, I recently leased a piece of land that contains the round mountain silt formation (shark tooth hill). Part of the deal with the landowners was to donate a portion of the finds to museums or schools. Does anyone know of any institutions that would be interested in accepting sharks teeth and other fossils? I would need a formal letter of acceptance to provide documentation. Please let me know, thanks Jesse
  22. ID for a Newbie Please

    Hello, I am a new member as of today but have been reading for a while. My son and I have recently gotten into rock collecting. We haven’t gone fossil collecting yet but hope to do so soon. We found these in Inland Southern California in the foothills of the Big Bear area. The site was next to a river or what’s left of it this time of year anyway. I have tried to rule out pseudofossils and different types of rocks. These also remind me of what a ranger described to me as jellyfish fossils while visiting the Bristlecone Pine area in CA. Similar samples were also on display. The second (larger rust colored spotting) might be igneous but I believe the first is sedimentary. Any help would be appreciated. Thanks.
  23. ID please

    Hi my friend gave me this last year as a joke. He noticed a picture of some small Gastropods form Florida I got from @Nimravis (maybe you may know about this Ralph ) and said he had a nice little one I could have if I had the room . I said yes please . He sent it in a massive box 24inches by 12inches . When I opened it , I found a Huge Pilocene Gastropod from California . If anybody can help with an ID I would be very grateful . thanks Bobby
  24. Capitola

    Took a short trip to capitola California during a blowout tide. “King tides” I think they are called. Anyway, there were tons of whale and I think seal fossils exposed. Hope you enjoy, Conor
  25. Hello again! Finally took some pictures of the rocks I was referring to in previous posts. These are the reason I asked for help ID previous rocks. I never new what coprolite was until I tried to find a reason why these rocks look the way they do. In person, they look like they contain chunks of turtle/lizard/fish/eggs/shellfish/etc type stuff, I believe what is referred to as inclusions. But it could just be some funky conglomerate. Either way I’m hoping someone can explain why they look the way they do! There’s about 20 or so of these on my property, just grabbed some and snapped some photos. I wish I had better lighting/camera so detail could be seen. Thanks for your time in advance! And if you have any thoughts please let me know! Property is located in residential Menlo Park, California (between San Francisco and San Jose), very close to the San Francisquito Creek. some were just laying on top of the ground, others were below and found when doing some yard work digging. Easier to to see the individual parts when rocks are wet as the colors pop, as supposed to blending in as a slightly reddish brown mud. Some seem to have a “skin” if you will around them, like a layer that can be rubbed off, allthough i have noticed once i rub it off the inclusions, a couple days later the colors seem to have faded. Also many of The inclusions that stick out of the rock give the appearance that they have been scratched off or bitten off, possibly just from hitting other rocks as well. The black inclusions are the easiest to see in the photos, however they are only a small fraction of the reptilian/crustacean/fish/ i dont know shapes that you can see
