  1. Happy holidays everyone. I would greatly appreciate help identifying the following specimen. It was collected in the Santa Susana Mountains of Simi Valley, Ventura County, California. It came from the Saugus or Pico Formation. Saugus is late Pleistocene to late Pliocene while Pico is middle Pleistocene to Pliocene. My uncertainty regarding the exact formation arises from the fact that (1) it was float material already weathered out of the formation it came from and (2) based on limited research and knowledge, I believe there has been a lack of consenus regarding differentiation of the two formations (see recent work by Richard Squires et al. in Valencia and R. Squires in Newhall). I assume it is marine since all of Pico is marine and Saugus is non-marine to marine. At first I thought it was a shark tooth when I picked it up but I threw that thought out the window when I realized it had three serrated edges. Measures 22 millimeters long and 6.5 millimeters wide. It is 4 millimeters tall on one end and 9.5 millimeters tall on he end that has the needle structure. There are three to four 'bumps' on both long sides on the end with the needle. The bumps look evenly spaced. I can and will do my best to provide additional info if needed.
  2. Unknown marine fossils

    During a trip I purchased a container of small marine fossils. I could identify almost all of them except for a few. Age, location, etc. unknown. Does anyone know what they could be? P.S. feel free to ask for more pictures.
  3. Fossil? Funny rock?

    Hi everyone! What about this one? It was found in a well-known fossil site, an old cretaceous sea, in central Spain (Maranchón, Guadalajara, Spain). I would say the texture suggests a living creature of some kind. Too bad it would be a small fragment.
  4. Virginia Miocene 10/21/18

    After an extremely successful and enjoyable first trip to the Miocene of Virginia, my dad and I decided to give it another go when we saw that another guided trip was being held in late October. Our first trip resulted in my two biggest teeth ever, massive mako and huge hastalis. This time around, there weren't as many people on the trip, which is typically a good sign because it means less competition. The conditions, however, were brutal. It was very cold, and on top of that there were extremely fast gusting winds that made the river look more like an angry sea. Luckily, the tide was remarkably low while we were there, so there was a TON of ground to cover. I ventured south in search of some large shark teeth, and was successful to an extent. I talked with a woman who showed me a decent meg she had just found, but that was just about the best find I saw all day. Although I didn't come away with anything spectacular this time, I still got a respectable haul consisting of lots of hemis, some decent makos, a couple massive Chesapectan, and more of the typical Miocene finds. A big thank you to @SailingAlongToo again, for his instrumental role in organizing and supervising the trip. Already can't wait to head out again. I know there's a meg out there somewhere with my name on it. I'll find it one of these days. Thanks for reading! ~David
  5. I spent a few hours fossil hunting on two separate trips on Forest Service land in Montana. The first trip was this past spring looking for Late Oligocene - Early Micoene flora about 90 minutes outside of Missoula. The second trip was during at stint over the summer at a fire lookout tower in the Flathead where I spent just a few hours one morning looking at Devonian and Mississippian marine layers. Besides the obvious, the trips were quite different. The spring trip was a drive to a road cut on a Forest Service road while the summer trip was a seven mile hike in. Additionally the medium is completely different; flakey, brittle shale compared with big, blocky limestone. You can keep non-vertebrate fossils as long as you don't plan to sell them. Prior to heading to an area, I look through publicly available research, lectures, field trips, etc. to find possible localities. I only found limited information on possible identification of the Late Oligocene - Early Micoene flora and most of if was unpublished graduate work from a nearby site with only some overlap on species. Please feel free to correct any id's or throw new ones out! I believe these are cercocarpus, a mahogany.
  6. Hey folks, I was wondering how you guys would approach something like this (or if samples like this are even worth your time!) There's so much going on I'm a little confused as to how and where to start. would you remove the gastropods individually, break the rock apart, sacrifice the broken ones in the search for more complete specimens, leave it as is? I went through the pinned messages and learned a lot, but was curious if anyone's come across similar types of rock and could give some insight. My goal is to hopefully find and extract some of the more complete specimens, and maybe discover some trilobites along the way! The plan was to chisel out as many surface fossils as possible, then strike the rocks with a sledge hammer to break up the pieces, give them a good hard scrubbing, then use my steel picks and chisels to poke around further however the resources provided to me by @FossilDAWG and @Kane (thanks again by the way!) described a number of rare, some now lost, trilobite specices from the same formation found in similar contexts alongside Ceratopea Canadensis, so maybe a lighter touch might be in order? I'm still a little scarred from the time I put a pickaxe right through an almost complete piece of 1st century terra sigillata once upon a dig </3 I'll definitely be looking into air pens/compressors (looking at you ME-9100) as well, but on my pay that's one of those 'somewhere down the line' sorts of purchases. If those are definitely the way to go however, I can always shelve these for that later day...they've been sitting around in a forest for this long, another few months wont hurt! I did notice while cleaning the sample below that there appeared to be two separate matrices, a softer one which I assume was the sand/silt and then the hard dark rock underneath. I've got a much bigger slab with a lot more going on, but I grabbed this little one to practice and learn on! My first target is that crystallized one which is slightly exposed on the top (bottom center of the picture on the right) followed by whatever that is beside it and that mussel looking fellow.
  7. Ottawa Marine Fossils

    Hey folks! It took some time but I've finally gotten around to uploading some pictures from my recent fossil ""hunt"! The quotations are there because the directions I left for myself from a prior trip included such extremely helpful tips as "left at the spooky demon tree". Turns out when you're a chicken a lot of trees look like spooky demons >.> It was definitely more of a sad confused wander than a full on hunt...but I digress. While I wasn't able to find the exact spot from before, I found an area with similar geological features, and after digging up about half a foot of loam around a small outcropping was rewarded with numerous individual rocks with all sorts of...things...all over them. I grabbed one giant 40lb chunk and a smaller one to play with and poke at to practice techniques. The smaller piece is on the bottom. Both samples were taken within feet of each other in a public forest just outside Ottawa, Ontario. The smaller piece I put in a bowl of water and gave a good scrub down with a toothbrush (brings me back to my field school days >.>) The surface and reverse of both are shown and I can provide more detailed pictures if necessary! I thought the crystallized shell things were pretty cool, there were quite a few more out there, but I'm completely unsure of what I'm looking at or if there was a way to extract them safely. I'm most curious as to what the circular things that litter the rocks are, but there seems to be a variety of other shells and tubey wormy things in there as well. Is there some sort of resource or database I could refer to for fossils from this particular time period/area? I'd feel bad constantly asking 'whats that!?" Anything neat here worth poking at with some of my archaeological pokers or have I found myself some very interesting garden rocks!
  8. Fossil ID please

  9. Fossil Books

    Does anyone recommend books books about Mesozoic marine chordates? ( German or English )
  10. Ear bone

    Hello, I found in last weekend my first ear bone in a Miocene - Burdigalian formation and I lwant to know from what animal. The fossil have +- 5 cm. Thanks
  11. Marine fossil ID

    Well, here’s another that we found today on the James River in Virginia. It’s 2.5 inches. At least I know this one isn’t asphalt!
  12. Fish...likely Tilly

    I have been hunting a SW Florida area that is predominantly marine fossils. whale verts, earbones, teeth, dolphin earbones, small shark teeth (Lemon, Tiger, Bull, Hemipristis), ray teeth , broken barbs, occassional GW, Mako, Megs. No significant land mammal material. Actually , out of commission right now, but I'll get back to it soon. Found a lot of these. This is my largest at 3/4 inch. Could be a tilly bone , but these are consistently the same, not finding any other types and little variation in the ones I have found. Think of Eagle Ray teeth as comparative sameness. Maybe some other fossil hunter has stumbled across these. Fish skull?
  13. Little clam?

    Went out to a spot on the Nansemond River in Suffolk, VA, and it started to rain right after. We arrived, so we had to leave. Some iron concretions and this little thing were all I found. It looks like a clam, but it feels rougher than the other clams I’ve found so far. It was inside of a larger rock. I believe the area is mid-late Pleistocene. It’s about 2 cm wide.
  14. Awesome Coprolite

    I just got an awesome coprolite. I generally hate those things, and would never pay money for one, but I came across this one and it has so many visible identifiable remains, I couldn't help being really impressed. Ive always wanted to see a coprolite that had clear remains in it. Sadly they're much smaller and harder to see in person than in these pictures, so I can only use these display pictures for the time being, until I take a magnified look. There's clearly fish scales, seemingly from different types of fish, and apparently squid hooks and such. I'm excited to find a good illuminated magnifying glass and really studying it up close:) Maybe even a microscope to take a closer look!
  15. Is this coral?

    Another from our hunt along the James River in Virginia. Is this coral?
  16. We had such a good time fossil hunting for the first time a few days ago, that it has become all our kids want to do. Took the kids to a site along the James River today. We found some cool stuff and were wondering if y’all could help ID some of them. Thanks in advance. I think this one is a bone fragment, but it’s pretty small, and I’m not sure if it’s even identifiable.
  17. Campanian microfossils

    Hi everyone! It would be amazing if any of you could help with identifying some marine microfossils I sieved. The origin is campanian (might be santonian) marine sediments. The location has yielded mosasaurs, fish, and sharks in abundance. But I have a few bone fragments that I have absolutely no clue what they are... Here are some of the mysteries:
  18. Vertebra identification request

    Found what may be a vertebra, sticking partially out of the ground on private property near Phoenix, Arizona in Maricopa County. The soil is hard-packed coarse sand/silt/gravel with areas of clay. A landscaper added a top dressing of decomposed granite and river rocks - a typical desert landscape design around here. The specimen likely was transported to the site in the river rock. Luck me! Other fossils found in the landscape material lead me to believe it came from a healthy and diverse marine environment with turtles, fish, shark, crocodilia, lizards, skate, snakes and mammals. The entire area was once an inland sea. The specimen is approximately 6.5 cm length x 5 cm width x 2 cm height. (Lateral measurement varies from 1.5 cm to 2.5 cm.) The vertebral body is 5 cm length x 4 cm height. Let me know what you think. The "tooth" on the distal side measures 2 cm.
  19. Marine fossil...bone?

    I've been down for a little minute, but on the mend and digging again. My first outing produced this guy. I found a pocket of kaolin, which is exciting because it seems to always hold nice pieces. I was not let down. I know it still is very encrusted, and I'm trying to navigate it, please bear with me. It's about an inch. When I pulled the nugget I saw a tiny spot of black- figured I had a small tooth or scale. Started prepping it and...what the heck is it? Doesnt look like shell. Never seen anything like it. And ideas? I'm anxious to learn about it. Thanks in advance!
  20. Hello, I've got 13 fossils of which I'm not sure what they are. All fossils are bought, which is why I can't say much about the geological layer and location they're from. I used a ruler with inches and cm sizing. I don't really have to know the 100% exact specimen (please feel free to give the details though if you have them), I would like to have a general idea of what I'm looking at. 1. Sold to me as bamboo, not sure if it is: 2. Sold as a waterlily, its a cross-section: 3. same story as up. I don't know what it actually is: 4. looks like a lizard foot, but it's probably coral. 5. Some kind of crazy stain?? 6. This is obviously a tooth of a carnivore, I would like to know if its mammalian or from a dinosaur. For this one, I would love to know the specifics but shoot away with your ideas on it. 7. Looks like bone, mammalian? Is it even bone? 8. Another piece of supposed to be bone. 9. Bone/wood? who knows? 10. looks like its bone, but really don't know.. 11. Looks like something from the sea... 12. Could be a tooth of a herbivore, could also be anything else. 13. The last of the bunch, its sold to me as coprolite but it doesn't really look like it. I would love to know your ideas on this collection. I am an amateur collector and I can identify some fossils/stones but for these, I really need your help. Thanks in advance.
  21. These are the most numerous former inhabitants(that can be seen with naked eye) in an area I'm studying. Cottonwood Fm, lower Permian, Flint Hills Kansas. There's an odd feature at the anterior end that may help ID it. Would these indicate shallow water environment?
  22. Miocene - Portugal

    Hello, I bought a new mobile phone and finally I can take some better pictures "in situ" of my finds. Last sunday I went to do a fossil hunting in my usual spot. Here I have only a marine formation from miocene. I've made few findings but I taked some pictures: A little Isurus sp. (Mako shark)
  23. Campanian Catch

    I’ve been traveling out of state a bit lately and tending to some personal things. Meanwhile, back in Southerly-Centralish Texas, I managed a quick look at some Campanian exposures. Some finds were common, some rare, all cherished. I’ve attached a few pics, starting with common stuff.
  24. I've been exploring a lower Permian site I think may have intermittently been a shallow marine environment. The location is Eastern Flint Hills, Kansas. What type and size of creatures would indicate a shallow or shoreline environment? Thanks ahead of time for any information.
