    Tiny Beetle in Amber: Clues to Landmass Shifts This news is a little old ( I believe it is from October 30) but still very interesting.
  2. Teeth that are "easy" to id?

    Hi! Im wondering if there is dinosaur teeth that are relatively easy to id when it comes down to a specific species? Like a dinosaur with very odd or distinctive looking teeth that cant be mistaken to be anything else. I know that isolated teeth is often hard or impossible to id , but maybe there is some exception ? Best regards Patrik
  3. Discovering new species

    Out of curiosity, is it a practice for people to contact museums about fossils that can't be/can't quite be identified? I was just thinking about how many new unknown species must be just sitting around in individual's collections. They find new species all the time that are sitting in the museums collection, so imagine how many are of things that no museum has ever even taken a cursory look at. I don't mean like sending pictures of every vertebrae you can't pin to a specific species, even though that's more than enough in some cases, but at least with the less usual stuff, even though I'm sure there are plenty of individual teeth or single vertebrae of undiscovered species in individual collections. I saw an amazing full Devonian "shark" for sale, and that's what got me thinking. It would be nice if it were realistically possible to let museums just browse through collections, just in case. I know that once a fossil is out of context it loses significant useful information, but there'd still be potentially lots to gain from even those.
  4. Sorry for my poor English. I inherited a large trilobite from Morocco. Size 22 x 34 cm approx, weight 6 kilos. Does anybody know what species it is?
  5. The pdf in question is The Genus Pentremites and its Species by JM Weller, 1957. I can't get it through my university so I'm hoping someone here may be able to help me.
  6. Hello! I have added an Andara diluvii today and I have seen on fossilworks.org, that this species was/is also considered to belong to the genera Arca (original designation), Scapharca and Diluvarca. Nothing unusal, it is often the case, that one species was attributed to various genera since its discovery. Just out of curiosity, I would like to ask, if anybody knows which is "the species with the most genera"? Thanks! Franz Bernhard
  7. Hi all, in what situation would we use the following naming conventions? 1) Tyrannosaurid sp. 2) Tyrannosaurid indet. sp. OR Tyrannosaurid indet. (which is correct?) 3) cf. Tyrannosaurid sp.
  8. Scientific Name Pronunciations

    Hi all, How do you all go about pronouncing the scientific names of species that you find? So far, I've just gone with what sounds right and tweaked it based off what I hear others say. Most genus and species names are derived from Greek and Latin I believe, so looking at pronunciations in those languages may help. But is there any outside resource that you all use, or do you just say it how you see it? I'd hate to disrespect a shark by butchering his name!
  9. The Cockles: Common vs Lagoon

    Hi all, So the Cerastoderma genus has (in addition to a few other fossil species) two extant species: C. edule (common cockle0 and C. glaucum (lagoon cockle). Both of these species appear (both fossil and modern) here in the North Sea, and their Eemian fossils are common finds at the Zandmotor. Now I have always been told, and read in most of my books, that the difference between them is that: -> if you draw a vertical line from the umbo downwards, C. edule is pretty much symmetrical while C. glaucum will have one side more stretched out. As can be seen in the picture above. Pretty straightforward. Plus, this is what I explained in one of my old Instagram posts: But, while searching a bit around, I just now saw on the Wikipedia website a picture of a symmetrical cockle that they claim is C. glaucum. And WoRMS also has some pictures of some more or less symmetrical cockles for the lagoon cockle! So I am very confused... What is the difference then between the two species? Looking forward to your answers! Best regards, Max
  10. A bunch of different Glycymeris

    Hi all, So, here are a bunch of fossil bittersweet clams (Glycymeris) from different locations. So far they are all labeled as "Glycymeris" (which I'm pretty sure is correct). But I would really like to put a species name on each of them. Therefore I am reaching out to you all, because hopefully you will be able to help me sort this out! 1) Glycymeris from Westerschelde, Netherlands; from the late Pliocene (2.5 million years old). I'm thinking G. radiolyrata, but I'm not sure... 2) Glycymeris from Westerschelde, Netherlands; from the late Pliocene (2.5 million years old). G. obovata maybe? Or G. variabilis???
  11. Need help identifying shark tooth

    Hello folks. I bought this tooth about 10 years ago from a seller in Georgia. He had no clue as to what shark it came from. I just recently made a necklace out of it and felt like I should know what species it’s from. It also appears to be very old. Anyone have a clue? Very much appreciated!
  12. Hi, I have these two same sized Hildoceras, I'm thinking one is a Juvenile as can see the mouth border and one is a large one that has broken, would this be correct and would you say both specimens are the same ? Thanks.
  13. Is this a wolf skull?

    Hi everybody! I found this fossil online, and it the description says "wolf skull, of a young individual. Found near the remains of a mammoth" Can you tell if it is a wolf skull, and which species it is? What can you tell about the pictures?
  14. Ammonite species ID help requested

    Hey all, at the suggestion of others, I'm posting a photo of an ammonite fossil for assistance on species. This ammonite was unearthed by my father in 1972 in Shasta County CA. It measures 25 1/2 inches long by 20 inches tall. Any suggestions and help with its species and rarity is greatly appreciated. I get that it is not a complete specimen but hoping someone can help, Shannon
  15. Brachiopod? Bivalve?

    I found this nice brachiopod/bivalve shell fossil during my trip this year to Okinawa. I believe it is cenozoic in age. I would like to identify the species. I successfully chipped it out of the rock- no, more like it popped out itself- and here's the photo.
  16. Belemnite species

    Following on from a post in the questions forum, I was trying to identify this species of belemnite that I picked up on Friday from the Oxford Clay at Whittlesey, and learn generally how to identify species myself, rather than squeak 'thunderbolt' excitedly. It struck me as unusual partly because its shape is different from most of the belemnites I see in the Oxford Clay, but also because of the strange white coating. Aragonite is preserved at the site, and I thought perhaps it had aragonite around the calcium carbonate rostrum. Sadly it broke as I extracted it from the clay. It is conical, depressed, very acute and has a deep groove. I was using Fossils of the Oxford Clay to identify it, but although it is most similar to Belemnopsis bessina, I then decided it couldn't be because it is not hastate. But rereading the description it does say it can be weakly hastate, and it might be. Also in favour of this specimen being this species is the flattened apex and kidney shaped transverse section caused by the deep groove. I was possibly overthinking things. It would be reassuring to have other people's input Other features include a strange ridge on the reverse. Not seen that before. Also, just for fun, an 8mm belemnite. I'm not expecting to ever identify it, but it's cute and I thought I'd share.
  17. Hello I found a very distinctive belemnite while fossiling on Friday, and want to learn to identify the species myself, and hopefully identify all of the more complete ones I have collected. I used this resource http://www.bgs.ac.uk/discoveringGeology/time/fossilfocus/Belemnite.html to classify its features, and looked at Fossils of the Oxford Clay by Martill and Hutson to try and find it. Unfortunately only six species are identified and this isn't one of them. I looked in British Mesozoic Fossils from the Natural History Museum, and while this has Jurassic Belemnites, they are too early. Trundling around online hasn't gotten me any further. I'm trying to be more systematic in learning about my fossils, and was wondering how others approached first learning about specific species, and if there are any resources you would recommend? And if anyone knows of a monograph on Oxford Clay belemnites, please let me know

  20. New Mosasaur Found / Fox News

  21. This fossil is likely a whole new species of ancient millipede. PHOTOGRAPH COURTESY ANDREW MACRAE By Brian Clark Howard PUBLISHED SEPTEMBER 28, 2016 Visitors to a world-famous fossil bed in Canada have discovered a handful of strange specimens that may likely turn out to be up to three new species of large ancient millipedes. The find was made by chance last year in the Joggins Fossil Cliffs, which stretch several miles along the Bay of Fundy. The fossils are being analyzed now in labs in the United States and Canada. Giant ancient millipedes are nothing new for the Joggins cliffs, which are listed as a UNESCO World Heritage site. Since the 1800s, the cliffs have yielded numerous finds, including tracks and segments of millipedes that may have been seven feet long. The new fossil millipedes weren't quite as large: They were likely about a foot long (still relatively big), says Joe Hannibal, a paleontologist with the Cleveland Museum of Natural History, who is studying the new fossils, along with Canadian paleontologist Melissa Grey. The many-legged creatures were likely vegetarians, as most millipedes are, says Hannibal. The leggy animals crawled through ancient forests, which are also partially preserved in the fossil beds in the form of tree trunks. (Watch a video of glowing millipedes.) The new fossils are likely about 300 million years old, says Hannibal, who just returned to Ohio after a trip in the field to Joggins. The fossils are therefore from the Upper Carboniferous or Pennsylvanian period, which is often called the “Coal Age,” since much of the world’s coal originates from deposits of organic material laid down during that time. In fact, Joggins was once mined for its rich coal beds. Fossils were unearthed by miners blasting through its layers of sandstone and shale. The specimens included other millipedes, but no one had seen anything quite like the handful of fossils that were found there last year by guests to the cliffs. The fossils are likely one to three different species, says Hannibal, who is helping with the analysis. They will likely fit into the group known as the archipolypods, which means ancient many feet. Members of this group have been found in Illinois, the Czech Republic, Great Britain, and beyond. Although many of the legs of the animals are quite well preserved, their tops are not in good shape. (See how a millipede toddler learned to walk.) “So we don’t know what their tops were like,” says Hannibal. “They might have had spines, like some of their relatives, which look like big bottle brushes. Or they might have had no spines. So far we don’t have any evidence.” The next question will also be exactly how the new fossils may be related to other millipedes, says Hannibal. (Learn about the world's leggiest animal.) The fossils are an exciting find, says Alton C. Dooley, Jr., a National Geographic explorer who has studied ancient life and is the executive director of the Western Science Center in California. The specimens prove that there are still plenty of relatively large animals awaiting discovery. "By the Carboniferous, life had become so well established on land that there were thriving biomes all over the world," says Dooley. "But the flora and fauna was in many ways so different from what we have today that it’s almost like an alien landscape, and we’re still a long way from fully understanding how all the parts interacted, or even what all the parts were." http://news.nationalgeographic.com/2016/09/fossil-millipedes-discovered-bay-of-fundy-joggins-cliff/?utm_source=Facebook&utm_medium=Social&utm_content=link_fb20160926news-millipedes&utm_campaign=Content&sf37237741=1
  22. Crinoid Species

    Hello everybody. I'm trying to identify my crinoids but nothing comes up. So my question is how can I identify my crinoids? BTW: Do crinoids even have species?
  23. I recently bought this Trilobite on eBay for about 8 dollars. Now that it has been shipped, I have some suspicions that it might not be real. I am aware that there is restoration on the right eye. But is it still real, is the matrix real?
  24. This mammoth molar was given to me a few years ago, and the owner could not tell me much about it. Based on the photos, can anyone tell me if it is real or a replica? I tried pushing a red hot pin into it to see if it was resin or not, and the pin did not go through. And based on the number of enamel ridges, does anyone know which species it might be? Thanks a lot.
  25. Here are two fossilized insect specimens from the Santana Formation in Brazil during the early Cretaceous period. Do let me know in your opinion, what type of insects do you think they were and if possible, their genera or species names will be much appreciated. Thanks.
