  1. Dilophosaurus ??? footprint

    From the album Dinosaurs & flying reptiles

    Eubrontes: Dilophosaurus ? Raised relief (footprint coated to stand out). 200 mya Triassic Erving, Massachusetts . Connecticut River valley. Clay sandstone **Sadly, something smudged the tip of the middle toe while still wet, and ruined the beautiful claw mark. Heel to middle claw tip = 10", & from tip of right claw to top of left claw = 8". The 2 main types you commonly see are Eubrontes and Grallator, but Eubrontes is different, as it is apparently understood to be pretty much dilophosaurus footprints. (Citation???) I know there are probably sometimes others' footprints that will fall under the name, but it seems to be to the point of Eubrontes almost being synonymous with dilophosaurus. (Citation???) I KNOW I'm going to take flak for labeling this as just "dilophosaur", and I understand why, but all in all, in this case I feel completely comfortable and safe using the name without a qualifier. I'm very sorry to all who are bothered and annoyed by it
  2. Strange - Centipede or Plant? Need help!

    Hello, I am brand new to the forum - I hunt for fossils often, but I am completely stumped here! I found this a few years ago in Slade, KY - inside of the Red River Gorge - in the Red River. I think it looks like a giant centipede, with some sort of antennae at the top, but one experienced fossil friend thinks it might be a cycad cross section. I see legs, a critter.. but he sees a plant. Hopefully one of you experts here can solve this mystery!
  3. Fossil sponge garden?

    These inclusions are in Broome WA Australia sandstone possibly just higher than the famous dino-foot prints. The shape, relative thickness of wall and lumen, the layout and spacing on the platform, and some of the detail on them, all remind me of sponges. Can anyone confirm. If so there is about an acre of them! The longer ones all lie prone or are aligned in the same direction. A fossil sponge garden or cruel geological hoax?
  4. Coal seam ?

    Very new to fossil hunting. I was wondering if I would be likely to find any other kinds of fossils in a sandstone outcrop with lots of what looks like coal seams running through it - see picture.
  5. Is this a fossil

    Found this on a beach near Anglesea in Victoria wondering what it might be ?!
  6. Is this bone ?

    Hi I’m a new member with little experience. Found this on a beach near Torquay in Victoria Australia. It had weathered out from a limestone/ sandstone cliff. Wondering if it is bone. Whale bones have been found in these cliffs in the past. Wondering what people think.
  7. No clue first fossil Colorado

    Any idea what this is? Found it in Colorado Springs CO.
  8. What is this seed looking fossil?

    Can you help me identify this fossil? Late Miocene/Miocene, Phillipines, Camarines Norte
  9. Greetings, TFF crew. I seriously doubt that there's any great mystery to what this fossil is, but since it's my first self-liberated fossil, I decided to post. I'd go out on a limb and say that it's some type of miocene scallop. I was driving through a local canyon, not far from the now forbidden zone in Old Topanga, when I spotted a decent sized piece of sandstone between the road and the crumbling hillside. I had my GF go out and grab it while I kept it safe with other cars. We could see what looked like the wavy edges of a scallop at the outside of the sandstone. There are still a few more in evidence. I was fairly careful, but perhaps not careful enough in retrospect, and didn't have a thin "liberating" tool, so I used the only cold-chisel I have. I tapped around, maybe 4mm from the subject's edge, and it split. I then used a little pick to clean out most of the sandstone. Unfortunately, some fossil material came off with a piece of the shell, but it's mostly intact. Surely I could have done a bit better, and will the next time. I'm still rather jazzed to have my first stone produce some "color". There's also a little dark piece that caught my eye. It's probably 10mm in length. It's probably some sort of quartz fragment, but then again maybe it's some sort of coprolite. Poop springs eternal, right? (Sorry) Cheers all.
  10. Unknown woodbine fossil

    Found this on a large piece of sandstone on an eastern cross timbers forest meadow in south central Denton county near the Denton landfill. Any ideas?
  11. Possible Batrachopus Track

    From the album FreeRuin's Finds

    A better, non-chalk image of a previous post. I think it might be a possible Batrachopus footprint (missing a toe, the rock is broken on the left side). Hartford Basin Portland Formation Western Massachusetts
  12. Possible Batrachopus Track

    From the album FreeRuin's Finds

    It looks the part of a Batrachopus footprint (missing a toe) with the proper size and location but I cannot say for sure. Hartford Basin Portland Formation Western Massachusetts
  13. Equisetites sp.

    From the album FreeRuin's Finds

    The imprint of a stalk from an ancestor of the Horsetail. Equisetites sp. Hartford Basin Shuttle Meadow Formation Massachusetts
  14. Shell Cast/Mold Conglomerate?

    Hi all, I took my Mom to lunch at Frenchy's Dunedin, Florida and than took a walk on the Causeway. I found this unusual piece that I was going to toss but kept it. It is about 3" by 2" by 2" and looks like granulated brown sugar with crystals (I think sandstone) under the eye loop. It appears to have about 4 shell casts on top with some of the seashell still embedded in the layers. On top it looks like a turtle with its head sticking out?? There is a dozen or more shell molds or imprints all over this conglomerate of sediment. What do you think of this find? Is it considered a fossil? Thanks in advance!
  15. Is this a Plant Fossil?

    Hi, I'm new to this forum and I'm a rock collector/hunter and found this interesting sandstone rock on the beach on the Gulf Coast of Florida. At first I thought the rock was engraved with the letter "L", but after further examination it appears to be impressions in the rock. What I thought was real cool is on the top of the "L" there is hair or fibers sticking out of it. Can anyone please help me identify this specimen???? Thanks so much.
  16. Preparation advise

    Looking for advise on a mosasaur jaw in sandstone. I’m wondering if I should do more prep to show more of the jaw still hidden in sandstone, the only problem is the jaw bone is fragmented. Any advise would help
  17. I’ve been running into some cool fossils at my study site in southeastern Ohio recently and thought I’d share some photos. This is deep in the hills of southeastern Ohio and most fossils I’ve seen in the area are weathered sandstone casts/impressions of Lepidodendron/Sigillaria trunks/bark in stream beds. Interestingly, these fossils seem to be clustered in 20-50 meter stream stretches. Pictures below are from one such stream stretch in the lower lying part of the ravine where some chert and limestone start showing up with the sandstone. I would love any additional information folks can provide on these rocks as many are too worn/indistinct. Also, does chert/flint ever contain fossils? The last picture is of a big chunk of chert (I think) that looked like petrified wood sort of to me. I will get around to posting some other/better ones from this area later! image2 by Andrew Hoffman, on Flickr image3 by Andrew Hoffman, on Flickr image4 by Andrew Hoffman, on Flickr image5 by Andrew Hoffman, on Flickr image6 by Andrew Hoffman, on Flickr image1 by Andrew Hoffman, on Flickr
  18. Found in gem laden scree field

    I'm not convinced that what I am looking at is in fact a fossil. I've checked several of my books on minerals and asked a few people and no one knows what these are. We were hiking some drainages in Central Colorado and found these near some copper deposits.
  19. Hyneria tooth? Lithunanian erratic probably Narva Stage

    Dear Guys, Today I splited small sandstone erratic, here I saw Asterolepis- like armour plates and found Hyneria tooth crown that is about 9 mm length and preserved with well visible cross section that lets to think it is polyplocadont like. The very similar greenish grey sandstones with red spots and the placoderm Byssacanthus pieces are decribed in the database fossiilid.info as from Narva stage (Middle- Late Eifelian, Middle Devonian) Talking about Eifelian tristichopterids I do not know any bigger forms, I just have heard about Tristichopterus. But judging by the size and the relief near root zone this tooth is especially similar to Hyneria teeth from Red Hill quarry, Australia. Maybe platycephalichthys is could be (it is known in Latvia and even Russia) but it is found only from Late Givetian and thrived in Late Devonian epoch... Please help me to find out anything about this question. Best Regards Domas
  20. Possibly bioturbated sandstone?

    I've been adventuring my family property in north-western Pottawatomie county, Oklahoma, for 15 years or so and I've always thought all this sandstone was kinda boring - there didn't seem to be any obvious strata, or differences in composition and no fossils. On Christmas day, however, I went out on the family property to do a bit of photogrammetry of the sandstone outcrops on the property and I stumbled upon a very interesting pattern in the sandstone: I have been told that it looks like bioturbated sandstone, and it certainly looks like some kind of biological pattern. This sandstone belongs to the garber formation in central Oklahoma, and is Permian in age. This is the only place I've seen such a pattern anywhere around here. Is anyone familiar with the garber sandstone or perhaps with similar formations/trace fossils?
  21. Possible fossil near Moab

    I found this which looks like a fossil to me just south east of Moab UT. I debated with my friend about if it was a fossil or not so I thought I would post it here and see what everybody thinks.
  22. Looking for ID

    Found this just south and west of St. Louis, Missouri. Lots of sandstone, flint and limestone nearby in a unique-to-this-area "hollow". Found while cutting a bench for hiking trail along a small rock face on steep sideslope. Roughly 600' above current sea level. Swift flowing Meramec River is within a mile but about 100' below even at (modern)historic flood levels. Most material on the hillside has migrated down from a much higher point. I don't generally keep rocks so will need to revisit for additional images. I've found lots of small fossils in a white, coral like stone as there seems to be a band of it that runs throughout the area. The car key is for scale but it's roughly the size of my open hand. The symmetry is incredible. Thank you in advance!
