  1. Fluorescent Exogyra by Daylight.jpg

    From the album Fossil Flourescence

    In the daylight, this is an articulated Exogyra shell from the Cretaceous New Egypt Formation as it runs through Mullica Hill, New Jersey. I brought it home because it had an interesting bit of vivianite replacement covering half the surface of one valve. When I brought it home, I noticed some white material inside the cavity of the broken shell. I figured it might be calcite, which sometimes fluoresces. So, I pulled out my UV lamp. To my shock, not only did the white material glow an interesting powder blue color, but the majority of the one valve glows an intense, bright red! Meanwhile, the other valve doesn't glow at all. Scroll right to see what it looked like in the dark with the UV lamp.

  3. Need oyster ID

    Can't quite figure out the ID on this oyster. Myrtle Beach Thanks as always! - Paula
  4. What is this shell #6?

    Can anyone help with a more specific ID on this oyster shell?
  5. Bivalve IDs from SC coast

    All of these were found beach combing in Charleston, SC and all were caked with what I believe is limestone. A. Not sure on this one. Thought clam before pulling away some limestone but now thinking oyster? About 5cm wide. B. Scallops, wondering type and age if identifiable About 3 cm tall. C. Was thinking scallop on this one but it doesn’t seem to have the same vertical lines, they’re all horizontal. Roughly 9cm tall. Thank you all in advance! I’ll be posting some corals and bones tomorrow if I have no luck finding anything myself
  6. Oyster?

    I am having so much trouble finding out what these are. I confident that they are some type of prehistoric oyster but I have yet to find out. Is there anyway some of you guys can help me? IMG_3374.HEIC
  7. Ifrane, Morocco.

    Hi, gang. Some of you may remember the Southern Morocco trip I took in February. One of the places visited was quite near to me, about 70 km, lovely Swiss style mountain town called Ifrane where I found some Middle Jurassic brachiopods and echinoids. See http://www.thefossilforum.com/index.php?/topic/93193-ifrane-middle-atlas-morocco/&tab=comments#comment-1026671 A friend offered to drive me up there for the day so off we went I decided to check some outcrops on the other side of the road this time so went and had a peek.Sorry, no photos this time as wifey didn't come, she was ironing her money and she has the only camera phone. The first outcrop is an oyster bed crammed with enormous oysters. This is incredibly hard and couldn't be broken safely. (safely as in getting the fossils out in one piece, not my own personal well-being). But I was lucky enough to find this monster just lying a the base: Scale in inches it would seem. I think I can clean it up a bit. Eventually. After i'd dragged my broken carcass a few hundred whatevers further on, the limestone became yellower, softer but still pretty hard. Lots of broken shell material, a couple of ammonite bits, but the only salvageable items were these couple of rather nice gastropods; again, they should clean up a bit better: Oh, the scale's in centimetres this time. I felt like a change. You know, it's amazing how often I've given up on a days collecting and then, on the way back to the car, you find something just in your path that makes the trip. Here was mine this time : Forgot the scale altogether. Sigh. Maybe four or five centmetres diameter. Harpoceras, perhaps? It has a very pronounced keel. @Ludwigia Roger? I'll be able to prep this pretty well in 2046 when i get to my Jurassic stuff. Nothing spectacular, but it's always so nice to be out in the field collecting. Life's Good. Adam.
  8. Here's another find I came across a while ago which looks to me like an intact oyster that has fossilized but I'm not sure on this. It almost looks like granite, but the shape is exactly the size of a small oyster - it seems to have some flakiness to it as well on the sides. Any thoughts on this? I tried to photograph all sides. If this was fossilized, any idea how old this would be?

  10. Late Carboniferous Oyster or Clam II

    A second large Clam or Oyster? I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer so that I could actually pick pieces up. After the heat this weekend, they were easy to pick apart once I got them home. Yesterday, I found the first piece. This is the one I found today. When it came out of the rock I was a bit shocked at how large it was. I carefully tapped around the specimen and was able to remove most of the surrounding rock carefully. This is the larger of the two pieces I found this weekend. I have less confidence in identifying it as has less features than the first piece. You can see shell material flaking off in the 3rd and 4th photos below. The fossil after I found it: Then, once I removed it from the rock:
  11. Late Carboniferous Oyster or Clam

    I love and hate finding large fossils. They are really interesting and striking to look at, but I have a hard time getting an ID on them. I dug a huge piece of limestone out of the hill and split it into three with a sledge hammer. After the heat this weekend, they were easy to pick apart. Yesterday, out popped this piece. There is another one I found today that I will be posting after this one. This piece has several wavy ridges. The shell material looks pearly, and perhaps some calcite replacement has happened. There was a piece of shell stuck on the mold portion as well. I'm seeing about 6 distinct ridges. Anyone know what it might be? Before I removed it from the rock: Several views after removing, trying to show the ridges:
  12. SW Florida Pearl Fossils?

    Hi everybody. I'm hoping someone on here can identify these. Last Saturday I was digging in the yard here in Alva to plant some citrus trees. At about two feet down in this area it's all coral and i found this conglomeration wedged under a cypress root. the tree is over 4 ft in diameter. i thought these were lizard eggs but after gently brushing the shells out with a soft toothbrush and dawn soap, i think these might be pearls. two of them actually did separate as you can see they're on the desk. we're seventeen miles from the ocean and this property was a cypress swamp prior to our house being built in 1974. Any thoughts on these ? My wife wants me to encase them in resin because they're unusual looking . Thanks.
  13. Found Giant Oyster?

    Hi, I found this giant oyster in the Mexican Golf. It weights around 13kgs. I found this article about something similar, where they did a MRI on the oyster. - https://www.dailymail.co.uk/sciencetech/article-2154813/amp/The-100-million-year-old-oyster-times-normal-size-undergo-MRI-scan-contains-worlds-biggest-pearl.html and here the same story with more details, but in spanish - https://insolitonoticias.com/ostra-fosil-de-145-millones-de-anos-podria-contener-una-perla-gigante/ Cheers.
  14. Rudist ?

    Hi, a friend of mine told me he found some Placentyceras in a place where the geologic ages go from the Albian to the Turonian-Santonian, but most of the stratas of that place are Cenomanian. I believe this fossil is not an ammonite, but rather an Oyster or a rudist. I mostly think about Requienia or Toucasia. The geologic file mention the name of Toncasia bayleia. Do you know if Toncasia is a synonym of Toucasia and do you think i'm right thinking this is a rudist ? Lenght : 7 centimeters.

  21. capital reef oysters II

    Hello all Here is a companion query for help. This item is flat, tapered to the top and slightly concave from the underside. The two pictures are a top view and a bottom view. It is about 2” thick. The scaliness, if there is such a word, looks like Exogyra, but does not have the curved narrow end described for Exogyra. I assumed this was a flat mollusk shell when I picked it up (E of Capital Reef, south of Rt 24, about 4 miles outside the park) but can’t find a match with the limited references I have. Help appreciated. Thanks. Tom
  22. Odd Texas oyster

    I'll post a full story in trips when I get time, but I was searching around a new spot, being unsure of the formation (Austin I assume now) I was picking up everything I found including oysters which I would normally leave, I assume they're exogyra or ilymatogyra but the Mark on the back is strange to me, 2 of the three I picked up had them and I haven't seen anything like it in pictures. Species and out formation ID would be nice
  23. MIOCENE ISLAND

    I should have posted this long ago, but am going to do it now, in the hope that then it is behind me and then I can look forward to future adventures. Due to ill health from 2012, finances and responsibilities, I have been unable to do any personal collecting except for this one wonderful trip which reminded me that I've still got it in me. In October 2016 wifey and I were relaxing in a bar on Tarifa beach, the southernmost point in mainland Europe, located at the south-western corner of Spain, opposite Tangier, the two Pillars of Hercules that are the entrance to the Mediterranean from the Atlantic. I noticed an island connected to the mainland by a man made causeway. it had a lighthouse on and some ruins, so I thought that being only a little distance, I'd go and explore. Here is the location, to the left of the picture is the Mediterranean, to the right, the Atlantic. There are no more location pics, I'm afraid, as wifey can't be prised away from bars very easily and she has the camera phone, but the island was closed to visitors without a guide or permit as it's a place for protected birds, the lighthouse and Napoleonic fortress ruins. But to the left of the causeway was a small beach with exposed rocks and even a little notice board explaining that the rocks were a Miocene oyster bed 5 to 10 million years old. My interest was aroused so I clambered about the beach and found the fossils in the next post. Very pleased with myself, I was, especially as I had no tools and the rock was really seriously hard. Had to use other bits of rock as hammer and chisels. And my breathing held out pretty well. I can still do this! Life's Good.
  24. Can you identify this oyster?

    I found several of these on Myrtle Beach. I think they’re my favorite oyster fossil. But I’ve checked a bunch of online databases and can’t figure out the name of it. It’s gold in color. I should’ve put a measuring tape next to it. They range from 4 to 5 inches long . Thanks! paula
  25. Ok, another new one for me today. I picked up one at Myrtle Beach, SC because it looked interesting, then found a second almost identical one. Now I'm thinking it's something worth knowing! It's dense and heavy. The top has a gray metallic sheen to it. Both of them have a middle circular area that looks rusty, and as if something had been attached there and pulled off. The back looks completely different. Where the front is smooth and shiny, the backside is rather dull. It is comprised of layers, and they layers come together in a knobby area at one end (again, as if perhaps it had been connected to something.) Overall, it really looks like a kind of clam shell to me, but the metallic sheen, rusty circle and layered interior don't look like any clam I've ever seen. Thank you again! - Paula
