  2. I recently acquired some amazing specimens from my good friends collection. These pieces were part of the William Pinch (8/15/1940-4/01/2017) collection. Bill is well known in the mineral community for his incredible collection of one-of-a-kind and rare minerals from around the world. Bill also collected other natural history specimens including these two wonderful fossil teeth. These fossil teeth were available in the 80s and 90s and are now very hard to acquire. I'm very proud to own these teeth from the Pinch Collection. Happy Collecting

  6. I found the below partial jaw with two molars several years ago in the Eocene Nanjemoy Formation of Virginia and donated it to the Smithsonian Institution. Dr. Ken Rose studied the jaw and wrote a paper on it which was just published on-line by the Journal of Vertebrate Paleontology. With Covid it took a bit longer to get the paper on this jaw written and published. Here is the paper citation: Kenneth D. Rose, Jonathan M. G. Perry, Kristen A. Prufrock & Robert E. Weems (2021): Early Eocene Omomyid from the Nanjemoy Formation of Virginia: First Fossil Primate from the Atlantic Coastal Pl
  7. With a week of collecting under my belt I felt ready and excited to take on the next, this time exclusively on the White River formation. All factors being considered, the White River is probably the most difficult formation to hunt among those I've been lucky enough to explore thus far. For one, the terrain is often very rough, with all sorts of ridges, rises, washes and gullies to hike through. Another issue to account for is the reflection of light off of the white sediments, meaning that ample sunscreen is a necessity if you don't want to burn to a crisp. That harsh sunlight can lead to te
  8. In Colorado there is a formation called the Dawson Formation also known as the Dawson Arkose Formation. The most common fossil by far is petrified wood and although I haven’t found any vertebrate fossils from dinosaurs and mammals have been found. It covers a relatively large time span from late Cretaceous to early Eocene, about 70-54 million years old. A member that has also found fossils in this formation, Blake @FossilDudeCO. Although it has been over three years since he was on his posts have still helped. He said that further south is Eocene but higher north in Parker and Aurora is Cretac

    Maryland Eocene shark teeth

    The two shark teeth below are recent personal finds from the Nanjemoy Formation (early Eocene) in Maryland. I'd appreciate any help in ID'ing them. #1: Jaekelotodus robustus? I've been calling this one Jaekelotodus robustus and am curious if that's correct. This tooth measures 27 mm on the slant. #2: Brachycarcharias lerichei? This second tooth has me stumped. I'm leaning toward Brachycarcharias lerichei, but would not be surprised to find out it's s

    Dolichopodidae indet.

    Taxonomy according to fossilworks.org. Diagnosis according to Sawabi et al., 2018 p. 7: “Small to medium slender flies; body length 1–9 mm; most species with greenish to blue metallic luster, while others dull yellow, brown or black in color. Eyes large and prominent. Antennae aristate. Ocellar bristles and outer vertical bristles well developed in most species. Legs long and slender. Wings clear or patterned with darker areas towards the wing margin; wing venation reduced; three radial veins R1, R2 + 3, R4 + 5 present; posterior basal cell and discoidal cell always fused; anal cell alway
  11. Going back several decades I have attempted to have an annual extended field trip; call it a fossil collecting vacation. Some years this happens, some it doesn't but this past November I had the opportunity to spend several days in the field visiting some of the classic Cretaceous and Paleogene river sites which abound in Alabama. Since I haven't had the opportunity to post much in my blog, I decided to post pictures from that trip here as I have time. First up are pictures from the lowermost Maastrichtian (~70 mya) Upper Cretaceous Bluffport Marl Member of the Demopolis Formation.

    Into the Eocene

    Most of my Maryland fossil hunts are at well-known Paleocene and Miocene spots. A few weeks ago, I got an itch to try something new and after studying a state geologic map and aerial photos, I found a potentially promising Maryland exposure of the less accessible Nanjemoy Formation (Eocene). It's an out-of-the-way spot and a lengthy trek along a river from the nearest public access point. As I discovered, it’s also kind of a brutal hike due to the number of downed trees and other vegetation lining the banks, forcing you to mostly travel through murky knee deep and hig

    Abnormal pet wood or bone/tooth (Conroe, TX)

    Frequently see pet hardwood along the San Jacinto river West Fork. This piece does not have the normal shape or tracheid/ray pattern of wood. I don’t recognize the ridges and I see small consistent pores at several faces. The wide depression in the middle reminds me of a Proboscidea tooth. From the right angle, it appears there may have been symmetry to either side. Any feedback appreciated. Thank you all!

    I found this tooth at abbey wood and can't find its I'd online, I've ruled out shark, leaving the possibility of mammal, reptile and fish. Any help is appreciated. It's about 5mm long.

    Florissant Plant Matter

    Hello guys, I have been digging through my box of Florissant Formation shale and I came across this piece of plant matter. I want to say it's a piece of a fruit or flower, but I'm not positive. @piranha? The piece of shale is small, about 1.5 inches long. It looks similar to a petal from this Magnoliophyta flower from idigpaleo.org. I think I can spot some differences, though. I'm hoping it's identifiable, thanks for any help you can provide!
  16. Hi everyone, today I arrived a small batch of shark teeth which came from the Egem Clay, Tielt Formation, Egem, Belgium that date back to the Ypresian, Eocene (53 mya). I attempted to ID them but as usual I would like to see what your imput is on my ID's. Tooth 1: Striatolamia macrota or maybe even Cretalamna sp. Tooth 2: Brachycarcharias lerichei? Tooth 3: Striatolamia macrota Tooth 4: Striatolamia macrota Tooth 5: Hypotodus verticalis or Striatolamia macrota
  17. I'll be honest, I've put off writing this trip report for far too long. Between work, school and general procrastination I have delayed this post for over 7 months. Perhaps there's a silver lining to me writing this in the middle of winter, it could act as a nice break from the grey & cold conditions many of us are facing this season. Hopefully you all enjoy a dose of warmth from a trip which I enjoyed greatly. Ok ready? Let's go. My morning started around 4:30, ungodly hours for me generally, but I woke up excited for what lay ahead. Less than a half hour later we were on our w
  18. I tend to buy a copy of every issue of Natural History magazine to encourage the local Barnes & Noble to continue carrying it. Sometimes, it's already gone when I get there, and last year, the magazine suspended publication for a few months due to COVID. In the current (May) issue, the cover story is "The Story of the Rose." It reviews the known fossil history of the flower against the background of paleogeographic and climatic changes across the Cenozoic Era. It also addresses how humans have valued roses going back as far as a few thousand years and how we have found uses
  19. Hello, I have been going through some fossils that I bought a while back. I came across this agatized snail from Morocco. I’ve tried to find more information on these agatized snails, but have been unable to find much. Some sellers online say that they come from Assa, Morocco, while others say they come from the Dakhla region. I’m also wondering what species this little guy belongs to, and a more precise age for these gastropods, although I’m pretty sure they are Eocene. Does anyone have any information regarding these agatized snails?

    Has anyone been to the Spanish Fork Canyon near mill creek for collecting Eocene shells recently. Is this area still accessible off skyline drive?
  22. Making the most of the last of my unplanned leave from work, I decided to make a trip to the Eocene Upper Parachute Creek Member of the Green River Formation in Colorado. Unfortunately, the road was not plowed and there was isolated patches of snow on the ground: I decided to walk the 5 miles to the site anyway through snow, slush and mud., although other parts seemed clear and pleasant Mostly, it looked like this though. I didn't count on the extra effort it takes to walk through hilly landscape with slush and mud, which made the walk seem longer than it wa

  24. Hi everyone! Today is received a bunch of unidentified fossil shark teeth found in a now closed sand quarry in Lede Sand, Lede Formation, Balegem, Oosterzele, Belgium (Eocene, Lutetian, 44 mya). I was hoping some of you might help me out with confirming the ID's of the teeth. I have some idea's what the ID might be, but I am not entirely sure about most. Tooth 1 & 2: Definiatly Sandtiger teeth with fine stiations on the crown. That makes me believe that these are probably Striatolamia macrota Tooth 3: Same goes for this one, I also be
  25. Hey all! Between an ill-timed conference, election month, the pandemic, online teaching, and a few other issues, I was way too stressed out and busy to be on here regularly since October. Also, in mid November we began digging up a small basilosaurid whale in Harleyville, SC - very likely to be the most completely known specimen of the dwarf basilosaurid Chrysocetus, and perhaps the most important basilosaurid discovery in North America of my lifetime. I did manage to write a blog post about our fieldwork, so as an apology for being AWOL and only getting back to identifying cetacea
