  1. Uncle Siphuncle

    Anniversary Ammonite Adventure

    My wife and I had a Belize trip scheduled last week to celebrate our 9th anniversary, but canceled it last minute to avoid Covid related travel inconvenience. Taking travel logistics back into our own hands, we threw together an impromptu driving itinerary to some wonderful parts of northern New Mexico, courtesy of our tenured friend, Pee Fooley. While Pee couldn’t join us, my wife’s Jeep faithfully delivered us to panoramic environs many miles off pavement. The air was crisp, skies clear, and the ground was dry. Biting winds kept us bundled up. I figured cell service might be
  2. I have been experiencing the most unusual predicament for over a month now - I've been finding more artifacts than I have my target fossils. I happen to live in one of the most prolific areas in the U.S. for impressive paleoindian and other native artifacts, and while I certainly have an appreciation for these, it's like "giving pearls to swine" - since my first interest right now is firmly cretaceous vertebrates. However, I am still regularly blown away by some of these artifacts, even though I don't know much about them. So, purists be warned! This trip report is yet another one

    Crinoid Segments

    From the album: Delaware Fossils

    Oddly smooth, but typical of this locality, these crinoid segments are only about 2mm in diameter. From the Cretaceous spoils deposits of teh Chesapeake and Delaware Canal, Delaware.

    Large tooth found in Grayson marl, shame the enamel is missing, since root is not all there not positive about ID, Cretolamna? The tiny tooth missing cusp from Eagle Ford and haven't been able to find match but then I'm horrible with teeth.

    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

    Where are all the British mosasaurs?

    Hi all, While I'm aware that current Cretaceous exposures in Britain are largely restricted to the south and east coasts of the islands (see geological map below; source), significant marine deposition is said to have taken place across much of Great Britain from the Aptian onward (source). As such - and especially considering the richness of the record of the marine ecosystem during the Jurassic- one would expect an abundance of marine reptile remains to be known from British Late Cretaceous sediments as well, the epitome of which, of course, would be the

    Cardabiodon?

    I recently acquired this nice little tooth from the Carlile Shale of north central Kansas, which I believe is Turonian in age. It looks like Cardabiodon ?venator to me, but I don't have much experience with the genus. What do others think? The tooth measures 27.17 mm along the slant and is 21.66 mm wide.

    Cretaceous shrimp claw

    Hello all, one of ny early 2022 trips has yielded these little beauties. With some help on the IDs a ghost shrimp claw (Mesostylus sp.) And partial Anomoeodus plate.
  10. I have been too busy to get out fossil hunting when I want but there are a few recent times I've been able to get out. I wanted to try and post a small trip report about them. On October 31 I had the opportunity to visit the W.M. Browning Cretaceous Fossil Park in Prentiss County, Mississippi. Most people from the area are probably familiar with this old site but I'm a new resident to this part of the South so I wanted to give it a try. It's Late Campanian Demopolis Formation. It was a little cold and rainy but warm enough for someone used to North Dakota. Apparently th
  11. Recently I acquired a bulk lot of Moroccan shark teeth after doing some reading and a lot of sorting. I have more questions than identifications. To keep it simple I stuck with the “square rooted teeth for the first round. I’ve come up with five categories 1 two cusplets - Serratalamna? 2 multiple cusplets but small - ? 3 two cusplets - Cretolamna? 4 two cusplets and no or very weak transversal groove - Otudus? 5 strongly reduced cusplets - ? If other pictures are useful let me know.

Suture is extremely simplified consisting of rounded, narrow lobes and wide rounded saddles. Cross section is variable from compressed to slightly inflated. Venter is variable from wide to narrow trapezoidal or simply rounded and in some species ornamented by fine crenulations. Sculpture is variable, too, ranging from smooth, unornamented forms to flexuous and ventrally ornamented forms. d’Orbig

    Undescribed shark from Toolebuc Formation, Australia. Albian in age. This tooth possesses folds along the enamel on both sides of the tooth (hard to see in photos), resembling those on Cretodus.

    Cretaceous Mammal Tooth Fossil ID Please

    Hi, I recently got this cretaceous mammal tooth from the Hell Creek formation, and I was wondering if you may help me find the scientific name of the species that it belonged to. I've done some research and learned that it was the premolar of a Multituberculate mammal. This order of mammals was diverse and there were many species. I think it might be one of the members of the Genus, Mesodma, Yet I could be wrong. I tried to narrow it down to the exact species, yet there are few examples to help me pinpoint to a certain Id. This tiny tooth is from Garfield County, Montana. it is from the late c

    What is this?

    I need to pick some brains. I found this at a beach, late cretacous in age in New Zealand. The site is known for belemnites, reptilian bones and fossil wood. I have no idea what this is. It has protruding thin lines spanning out over both ends that have been replaced by calcite or quartz. The lines can be seen along the length of one side and on the other side there seems to be a circle with new protruding thin lines. Could this be pine needles? It's the only thing I can think of? Some parts almost have a woody characteristics, and other parts with fine to medium sand textures.
