    Another fossilized bone fragment?

    Had a king tide combined with a storm front resulting some significant beach erosion and movement here in SoCal. Rockhounding today scored some pretty agates and this unique piece! It resembles others I’ve encountered on the beach (you might see one or more of them in previous posts). So, the question is…is this fossilized bone? Part of it looks like it, but another part doesn’t, so much…

    Fossilized bone ID

    I found this (presumably fossilized bone) loose in southwest Missouri. Am I correct in my presumption.

    Cetother Bone

    I found this bone in the sea cliff at Poplar Beach in Half Moon Bay, California. I found the bone partially sticking out of the cliff about 30 ft below the top of the cliff facing the ocean. A reputable marine biologist, Dr Bob Rubin, identified the bone as being the head of humerus from an extinct whale species known as Cetother. This whale species went extinct about 10,000 years ago and is related to the Grey Whale.
  4. I found this yesterday beachcombing At Otter crest, just after high tide " King Tides" This Beach is between depoe Bay and Newport Oregon.. I also found 8 agatised gastropods and 2 agatised mollusk's.. but my question is what this belonged to?.. I'm sorry I only had a centimeter or inch to measure with... So I chose the centimeter.. the closest thing I can find online seems to be a Vertebra.. it is completely mineralized and in the light glitters like Crystal. I rock hound quite a bit, but this is out of my privy... Lol can anybody give me more information?

    Possible Fossilized Rib (ID Help)

    Found this fossil in a riverbed in Fannin County (North Texas) while hunting for fossils from the cretaceous period. (This is a follow-up from the same trip as my previous post - thank you to those of you who helped ID the mosasaur vertebra! And also thank you for correcting my terminology on mosasaur vs mosasaurus ). I'm not totally sure what this is (at first I thought it was nothing too special - possibly just a very eroded Baculite as we were finding many of those in the area), but on closer inspection, there are fine striations on the fossil that make me think it is bone. My current guess (based on those striations and the longish/slightly curved shape of the fossil) is that it is a fragment of rib, and further, (based on the facts that everything else we were finding was from the cretaceous and that mosasaur are the only large marine vertebrate that I know of being regularly found in the area), that it is a fragment of mosasaur rib. However, I am not sure about this and am hoping for some more help on identifying what I've got here. I hope these photos are good enough to see the details (i've tried to shoot them in half-decent light). If you zoom in, you can see the striations I'm talking about fairly well. (See dime for scale). Here are both sides of the fossil Here are the ends And here is a closer shot of the more intact side So in summary, I'm wondering if I'm right (or even on the right track) that this is a fragment of mosasaur rib? And following that up, whether ribs are identifiable by speciesm (probably not, but worth a shot )? Final sub-question that is probably totally speculative, but I'm curious about: there are a lot of indentations and gouges in the fossil. Is it possible that these are marks from a predator and/or scavenger (e.g. sharks) chewing on the dead creature's carcass? Or is it more likely to just be erosion? Thanks for putting up with so many questions!
  6. I found this fossilized vertebra in a riverbed in Fannin County (North Texas) while hunting for fossils from the cretaceous period. My understanding is that the concave/convex ends of the vertebra indicate that it is from a mosasaurus, but I am very new to this so I don't have a lot of faith in my ID skills. If it is a mosasaurus bone, is there any way to determine species? I've read that Tylosaurus and Platecarpus are found in the area, but don't know if there are reliably identifiable differences in their vertebrae structures. Is this a mosasaurus vertebra, and if so, is there any way to determine species? Thanks in advance for your help : )
  7. Have I found a tiny fossilized mammal jaw? Found from the gulf of kutch(65-2 mya) late cretaceous-tertiary. It was found in a creek .

    Pet. Wood v. Coral v. Bone?

    Hi. We picked this up thinking it was a piece of petrified wood. But upon closer inspection we think it could be something else. Our family is still learning and this has us stumped. It was found on one of the beaches in southern Oregon, we don’t remember which one. Thanks!
  9. Good morning! I share with you two findings that, as a rookie, I have collected with great enthusiasm on the beach in Alicante, a mediterranean city in Spain. The first, I think they are two small fossils collected in a small stone. The second, if I'm honest, I think it could be a bone. He was on the shore of the sea, among the stones. To the touch and to the sight, it did not seem like a conventional bone to me, but when I looked closely, I seemed to appreciate that it has an articulation socket area at both ends. I found it curious to say the least and I share it with you so that you can give me your opinion. I don't know if it is a bone that for some reason has reached the sea and has been there until the current has carried it to the coast. The "bone" (let's call it that until you confirm that it's just a stone and I feel like a fool), measures three centimeters. Thank you very much to all of you and excuse me for my mistakes writing in english.
  10. Here's something I found while rockhounding in my back yard in Richmond, VA. There are an abundance of agates in the area which is (I believe) geologically speaking, from the Cretaceous period. The striations on the broken side looked different from the other cracked quartz pieces from the area. They looked more like pores. It could be xylem from something botanical, but the rounded part makes it look like a joint. Also, on the rounded side, there is a part of it that looks like it might be where a tendon would attach to bone. There are numerous limestone caves in Virginia, so perhaps it is a stalactite? Or, maybe it's just another hunk o' quartz. I apologize for the omission of a metric ruler for scale, but I've included a US quarter for scale. (US Quarter 24.26 mm or 2.426 cm) Thanks for looking!
  11. Found this yesterday in Texas (Gulf coast plains area). Looked like petrified wood at first but now I'm not sure. Either end is very pourous and looks a lot like the inside of a bone.

    Strange little find

    Hi all, This is a tiny little find from a creek here in Florida. It could be nothing more than a polished bit of fossilized bone with some coincidental marks, but the markings are odd to me. I haven’t found bone pieces with such symmetrical and aligned cuts like this before. I was wondering if anyone has any ideas what this may be?

    Gator/bovine bone?

    Hey guys! I'm hoping someone can help me ID this bone? I found it a little while ago in a river close to me in south Florida. I feel like it’s something obvious like a gator or a bovine but I can’t get a definite answer and it always drives me nuts when I can’t ID a bone! I’ve found one or two others similar to this in the past.
  14. Collected in northeast Iowa which is part of the Driftless, very rugged with lots of streams and flooding that cut away the earth. Most fossils here are Ordovician. Most are limestone of the Galena Formation. HOWEVER, this area is a hotbed for mammoth and mastodon teeth and bone finds that the locals call "dinosaur bones". That said, there is an area recently rumored to have a lot of "dinosaur bones" just 30 miles southeast east of Spring Valley, MN on the edge of Iowa. No one wants to talk about it for fear the government is going to come and confiscate their finds. Posting for a friend, so not my find. This is truly an intriguing rock. Spherical, I want to say "cherty" like a possible internal mold, the straight line and the way it is cracking almost like shell on the outside is also interesting. This could just be a very cool rock or...??? He sent me pictures and I am posting it in hopes that someone has seen something like this before. Since I am not very familiar with fossilized bone except for the real dino bones I have from the Hell Creek Formation, I would appreciate any sharing of knowledge that you guys and gals may have in what to look for in that area - @old dead things 1 2 3 4 5

    Please help identify

    I found these on the surface of the Mississippi River bank in Natchez Mississippi within 20’ of each other.

    Help with ?Fossil Identification

    Hello All! My husband and I are building a home in Central Kentucky (Frankfort) and have been finding a plethora of agate, jasper and geodes. I found some odd looking "rock" that I was puzzled about. It looks a lot like a scapula maybe, is very porous looking under the microscope and is very heavy. When I put my tongue to it, it sticks. The specimen is about 5 inches by 3 inches. Here are the photos: I would greatly appreciate any input anyone has for me. Thank you, Annette
  17. Yesterday I took a short trip to Crystal Beach, Bolivar Peninsula, TX. I found plenty of tumbled fossilized bone fragments, but this one caught my eye. I have no idea as to what it could be from, but if I had to guess it might be some bone from a fish. Maybe one of the many knowledgeable forum members can help me out. It is very thin, no more than 3 mm, and about 2 cm in length. It probably comes from an offshore deposits of the late Pleistocene, Beaumont Formation, which has been known to produce mammal remains and shark teeth.
