    A Fossil A Day.....

    A Fossil A Day....keeps the blues away! Or something like that... I started an Instragram account (jamielynnfossilquest) and am posting a fossil a day, so I figured I should do that on here, to REAL fossil enthusiasts! I'm a few days behind, so I will start out with a few more than one a day but then it will settle down to One Fossil (but I will admit, I'll probably miss a few days, but I'll double up or whatever.) I'll start with Texas Pennsylvanian era, but will branch out to other locations and time periods, so expect a little of everything! So enjoy A Fossil A Day! Texas
  2. Wonder if I can please get an ID on 2 items from the Potomac Group of Maryland. First item is a small item the size of a nickel. Second my imagination wants me to think it’s part of a foot print, which is the more common find from this formation. thanks so much for all insight, Matt
  3. Hi all, got some ammonites here that I desperately need help identifying! They are all from Folkestone, Kent from the Gault Clay of the lower cretaceous. There are also a few gastropods that I can't ID either. Thanks in advance for your help!

    Unknown Small bone

    Hello All I have found this small bone in marine Cretaceous material from NW Queensland. It is very small less than 5mm long it doesn't appear to be fish in nature( could be wrong thou) and seems very small to be turtle. Does anyone have any thoughts? Update thanks to some great help it now appears that this is a small turtle phalange. Cheers
  6. Hi everyone, I'm Roger. I need some advices to proceed with the preparation of vertebrate material from Cretaceous marine sandstones of the Parras Basin in northeastern Mexico. I have some isolated mosasaurid centra with adhered matrix (mainly sandstone, as well shale) and some tiny shark teeth embedded in sandstone. I seek to use chemical methods. I have heard of the use of dimethyl sulfoxide but have never actually used it, if anyone has experience with this reagent I would love to hear your feedback. I am not opposed to working with mechanical methods, but I do not have the nece
  7. Hi everyone! Fun story behind these. I bought them when I was about 15 labeled as "Mosasaur Vertebrae". As I've gotten older and (hopefully) more experienced I'm questioning that ID after pulling them out recently. All three are from the Moroccan Phosphates. So what do you all think? I'm leaning towards croc on the third and Elasmosaur on the other two with a slight possibility of the first being really primitive whale, but I'm not sure. Any insight is greatly appreciated as always! Vertebra 1: 49.4 mm long, 52.36 mm tall, 36.54 mm and 34.8 mm wide. one

    Is this a Spinosaur Vertebra?

    Hi everyone! I'm actually fairly certain this is Spinosaur based on the S. aegyptiacus holotype drawing which shows a vertebra with a bump of bone on the bottom and nothing on the sides of the centrums (I cropped that part for a reference) but Kem Kem stuff is weird so I figured it would be a good idea to get a second opinion. The bone measures 10.1 cm tall without the bump of matrix on top, 5.4 cm long, and the centrum widths are 5.15 and 6.15 cm. Any insight is greatly appreciated as always! Also Happy Thanksgiving!
  9. The unnamed giant Tylosaur of the Moroccan Phosphates is revealed at last. The great and mighty Hainosaurus is a previously unrecognized macropredator present in the latest Cretaceous (Maastrichtian) of Morocco. https://www.researchgate.net/publication/365437927_First_Record_of_a_Tylosaurine_Mosasaur_from_the_Latest_Cretaceous_Phosphates_of_Morocco Authors: @Praefectus @BrennanThePaleoDude @pachy-pleuro-whatnot-odon Abstract: The latest Cretaceous Phosphates of Morocco preserve the highest biodiversity of mosasaurid squamates anywhere in the world.

  10. Hi Everyone, Last month I took a trip from New York to Elizabethtown, Kentucky to attend my parents' 70th anniversary. My sister and her husband, two of her adult children, and my parents, both in their 90s have all resettled there. I try to visit them at least once per year, but my parents' 70th wedding anniversary could not be missed. It is a very long trip from the suburbs of New York City to E-Town and a stop along the way was the sensible thing to do, so I spent the night in Harrison, Ohio near the border with Indiana and only 15 minutes from St. Leon, the well known Ordovician roadc

    Ankylosaurus tooth

    From the album: Hell Creek / Lance Formations

    One of my favorites as a kid - the archetypical Ankylosaurian - Ankylosaurus. Ankylosaurus teeth appear to be fairly uncommon in Hell Creek - some paleontologists have suggested that Ankylosaurus may have lived in the highlands or nearer the coast of Laramidia. Most "Ankylosaurus" teeth you see for sale are actually Nodosaurid (cf. Denversaurus), for whatever reason, they seem to be far more common. Ankylosaurus teeth also often have wear facets, as this one does. The denticles give their teeth a "leaf-like" appearance. Given their shorter stature, Ankylosaurians probably were low-browsers.

    Strange etchings

    I live in Parker County. Per my brief research, the land I'm on was part of a shallow sea during the cretaceous period. I find countless fossils of ammonites and other small ocean based animals embedded in the rocks. Nothing that is particularly amazing or show worthy IMO, but I still enjoy looking at them. Last night I did find something that I thought was kind of unique. At first I thought it might be an Indian artifact with some etchings in it, but upon closer examination, I think the etchings are natural from small tube worms or something of that sort.

    Anomalies on Petrified log

    Back in August I was catching feeder fish in a wretched little Woodbine tributary when I pulled this out of the muck. It was black and limestone color with thick algae, it was unrecognizable as wood but there were holes and ripples that gave me hope. Hauling this (24 lbs) and my gear & fish was a challenge up a vertical bank and 100 yd walk through thick thorny brush for a 100 lb person, almost left it halfway back to car. After a good scrubbing it still looked like a chunk of water worn sediment and I deleted the first pic of top side, then I tried a new cleaning method I was using on a

    Tyrannosaur premaxillary tooth

    From the album: Hell Creek / Lance Formations

    This kind of incisor-like ("incisorform") tooth was originally thought to have belonged to a large, Cretaceous mammal. Later discoveries revealed that these teeth were actually the front teeth ("premaxillary teeth") of Tyrannosaurs - and are now known as a hallmark of their clade, Tyrannosauroidea. Closely-spaced, parallel grooves on bones suggest that Tyrannosaurs used these teeth to scrape meat from bone. Given the size, this is from a very young animal. Should Nanotyrannus be valid, then this should be considered an indeterminate Tyrannosaurid.

    Pectinodon tooth

    From the album: Hell Creek / Lance Formations

    Pectinodon (meaning "comb-tooth") is a tooth taxon, since no remains attributable to the genus beyond teeth have been found. Pectinodon seems to be a rare member of the Hell Creek fauna, with their teeth being fairly uncommon (though being so small, I'd guess that few people actively search for them). It was a small Troodontid theropod, with teeth that couldn't handle stresses as well as their Dromaeosaurid and Tyrannosaurid cousins (Torices et al. (2018)). This coupled with their small size suggest that Pectinodon was a small/soft prey specialist, preferring the rodent-sized mammals of the ti
  17. The Kem Kem Beds are full of poorly understood Dinosaurs but the isolated material that wind up in collections are beautiful. The Beds consist of three formations: Ifezouane, Aoufous and Akrabou. I believe the first one is your primary Dinosaur producing layer in the Cenomanian age. The teeth that we see bombarding us at shows and online give us clues to the spectacular dinosaurs that roamed that region. Claws give us another perspective and by associating them to other regions we obtain more hints of what they looked like. A Dinosaur that no one needs introduction is Spinosaurus. I
  18. Hi, I have been recently to a Cretaceous quarry in Kazimierz and I found these. I believe this one is some sort of a sponge - can anyone confirm or correct this assumption? This one too, I guess. I also found two specimens like this - they look like some kind of bivalve. Can anyone help ID those? I will appreciate any clues as whay these might be. Kasia
  19. I've found this one yesterday in the Mishash formation (Campanian-maastrichtian). A friend suggested that its a shark vertebra but I never seen one in that shape. Any help would be great. Thanks. Also, I'll put a picture with scale soon. VID_20221117_162227.mp4

    Cretaceous Montana Ammonite

    I recently bought this ammonite from montana, any idea on its genus, There are baculites within the matrix surrounding the ammonite, so its Cretaceous, probably from the Bearpaw Formation? but I cant decide what genus it might be? a few candidates ive seen are Holoscpahites, rhaeboceras etc, any help on narrowing it down?
  21. So a couple of weeks ago, I, along with my younger brother, decided to embark on our first field trip with the Dallas Paleontological Society. The destination was Moss Creek, a decently sized waterway on private property that feeds into the NSR. Just like in the main river, we were seeking a red layer exposure of the Ozan Fm (though I read that this red layer is different from the one at the river). This site is famous for its abundance of marine microfossils, namely shark/fish teeth. One of the people on the trip was a researcher (Shawn Hamm) who is currently finishing up a paper on this very
  22. Hello, I am posting pics of several Ankylosaurid teeth I found in the Mesaverde Formation in Wyoming. Can anyone ID them as to a certain species? "NOTICED PICS LOADED UP OUT OF ORDER, 2ND PIC GOES WITH LAST ONE" I know I need better pics but my current phone takes terrible close up pics. I know that you can buy a lens that you can attach to the ohone for pics; does that work well? Anyway, these are from at least 2 different sites and we're found over the course of a couple of years. Thanks!

    Mammal tooth ID needed. Cretaceous-JRF

    Hello, I have a number of Cretaceous aged mammal teeth that I would like to ID. Here is one I found recently in the JRF of Montana. I have a hard time taking pics of small teeth but I hope these are good enough for someone to ID it. Thanks for any help! It is about 3 mm wide.

    Kem Kem +x bones and teeth

    Hello dear fellow forum members, I have been offered a bundle of bones and teeth from one of the formations subsumed under "kem kem", although the more blackish ones seem to be of a different preservation than the "classic". There are quite some interesting pieces in there, amongst some turtle bones I think. I would be grateful for any hints on ID you can give me. first some of the tentative turtles.
