    Have I found a gastropod?

    Hey everyone, I was walking along Maslin Beach (South Australia) and a found this rock. I knew straight away that it looked very strange. Does anyone know what this strange shape could be? I'm guessing maybe a the remains of a gastropod shell? Thanks!
  4. This is the largest gastropod I've found and with intact aperture to boot. Is it larger version of the smaller ones? Is that a turritella next to it?
  5. Another rediscovery with my loop, I would swear I'm looking at innards but I know better. Not the usual broken shells I'm used to seeing, not the usual replacement, first time I've seen red on a fossil. What's going on in here? Oh and last pic, are those tiny gastropods? Smaller be than a pin head that's best shot I could get.
  6. Hello, I purchased this specimen a few months ago at an estate sale. No label, no information. The fossil has been split lengthwise, polished, and the interior void space looks to have been filled with a sort of yellowish epoxy. Each half measures approx. 4.75 cm long x 2.5 cm across. Original depth before cutting looks to have been around 2.5 cm. I believe it is a Turritella, in a distinctive layered, calcareous concretion. I was able to find a photo of an almost identical specimen on a college professor's website, but I was unable to get additional information after following
  7. Found these on last year's fishing trips on the Trinity, there are no gravel banks on this stretch just dirt and some rocks here and there. Now is this a stone with a butt crack or very worn Echinoid? Has the makings of one, if it is I've never seen one turned to stone like this, how old might this be? The seashell was a surprise to find, I know it's worn but is it a whelk? And would it be pleistocene?
  8. PaleoOrdo


    In the Kalvsjøen formation in the Oslo field I found these two stones. I wonder if they are gastropods or something else? The formation is of a rawthyean age late Ordovicium, the last period of Katian, before the Hirnation extinctions. Next fossil:
  9. Was visiting a quarry in NW Ohio two weeks ago, and came across this gastropod. It's about 2" X 1.5" Had to do some research to identify it. Saw that not too many Platyceras dumosums have been discussed/presented on TFF. It's completely pyritized. Inside and out Here's a drawing of how they're thought to have looked Another view It also has some non-pyritized bryozoans (I think?) attached to the coil. How does this occur?
  10. Found in the levant on a slope with a lot of material spreading from the cenomanian to the Eocene. Can you help me with the ID? I thought it can be some kind of a gastropod but I know there are similar heteromorph ammonites in this shape as well. Any help would be appreciated.

    Gastropod? Speleothem? Rudist?

    Hello together, I just remembered an interesting specimen I have had for many years, my uncle gave it to me when I was a kid. Unfortunately I have no information on its origin. It has some structures that may be diagnostic to the right eye though. Some pictures of rudists I recently saw reminded me of its general appearance, but now looking at it again I wonder if it is a big gastropod columella. the reddish middle part marked in black is actually standing out much more than the flashlight-picture shows, with cavities left and right that may have connected behind before being covered
  12. Hello everyone, I found these gastropods along the Sanibel Causeway in Ft. Myers, FL. They were in a pile of shells being used for landscaping so I presume that the sediments came from a nearby quarry of ?Pleistocene age, possibly the Caloosahatchee Fm. Can someone help me verify and identify this fossil? Thank you!
  13. What kind of gastropod is this? Found in east Tennessee?

    Gastropod in Colombia

    I've found this about 50 miles from the Caribbean Sea in Colombia, in a cut made to a hill for a highway to pass through. The layer where I found it is almost vertical. I've looked and found similar shells in the web, but no one has the same grooves. Can anyone help me? Found near 8.531326033223863, -75.68011324026482

    As battered as this is, it is an unusually well-preserved specimen for this locality. Although there are brachiopods and bivalves that preserved as calcium carbonate at this locatlity, most gastropods in the Cretaceous of Delaware are either steinkerns or are preserved as battered phosphate with phosphate in-fill. Gouging appears to have occurred after fossilization since the matrix does not completely fill the gouges. Most shell predation at Reedy Point came from clionia sponges and boring clams. This resembles neither. This was found in loose sand from dredge spoils.

    Gastropod Need ID (with echinoids)

    GlenRose Formation 105 - 115 MYA Found near roadcut in San Antonio Im thinking Tylostoma but I'm not sure. Maybe someone can chime in? Also check out these echinoids I found there as well (and the hermit crab claw)
  19. Location is in Missouri The area is dated to the Pennsylvanian Formation: Iola limestone formation Subformation: Muncie Creek Shale Member Hello and happy valentines day ! I was re-examining my old collection of Muncie creek shale nodules and found these peculiar specimens Originally I posted an image of one of my larger heart shaped fossils in my member's albumwhere someone mentioned it could be some sort of bellerophontid gastropod but now that I found a second more complete specimen I think it was time to ask fossil ID to get more eyes and possible identifi
  20. As I am working my way through the Keasey fm. rocks looking for fossils, I was gathering up the shards and small pieces and I notice a small piece of shell in the deep water piece I was working. Kept it just to check it out. as you can see the gastropod (I think, closest shells with the ribbing and rings are Bruclarkia columbiana and Solenosteira macrospira (does not seem to have been found in the Keasey Fm.)) The rest of the matrix is very hard and the dental picks won't scratch what is left. I think the center shows this is definitely a Gastropod but only a partial shell and one that is rea
  21. Hello, I found these gastropods in north Cape Coral, FL. They were in a pile of shells being used for landscaping so I presume that the sediments came from a nearby quarry of ?Pleistocene age, possibly the Caloosahatchee Fm. Can someone help me verify and identify these fossils? Thank you!

    Florida Gastropod Identification Help

    Hello, Please see the attached photos, I found this along the Withlacoochee River in Madison County, FL. Up the river from the limestone is Madison Blue Spring State Park located approximately ten miles east of Madison, FL. The limestone is from the Oligocene age Suwanee Limestone and I am interested in learning more about the spiral shaped gastropod in the center of the photo. There are other interesting shells in this specimen as well. Please see attached photos for reference. Thank you in advance! Greg Kruse Casper, WY
  23. So, I went out to check on my rabbit today. She’s been digging a big hole in the backyard, making herself a home. I was going through the dirt, seeing if I can find anything. Sure enough, I found something. As weird as it may sound, my rabbit found this, not me. I just found it in her dirt pile. It looks like remnants of a gastropod and a fossilized bone encased in a rock. Anyway, I thought it was very funny. I wanted to show you what what she found. Pictures are attached. Jared

    California Gastropod Identification Help

    I purchased this large gastropod fossil at a rock and mineral show back in 1991. The location is from Capitola, California, USA and I believe that it may be Pliocene in age. Any help in identifying it would be greatly appreciated! Thank you!
