    Early Jurassic plant for identification

    Cianfaglione posted a topic in Fossil ID

    Here is a recent plant fossil find from the Early Jurassic East Berlin Formation in Hartford County, Connecticut, USA. I gently rinsed the fossil a couple of times thinking it may be a fern-like "false fossil". But from what I could tell at this moment, it may be legit, especially since part of the fossil is overlayed with sediment. Comments, or a possible identification would be greatly appreciated. Thank you!

    Diademopsis crinifera Plates

    From the album: My Echinoid Collection

    Diademopsis crinifera Shale Plates Tafelfleins Bed, Posidonia Shale Early Toarcian Age, Early Jurassic (~183 Ma) Holzmaden, Baden-Württemberg, Germany Acquired online, September 2023 A neat couple of black shale plates containing several fragmented specimens of this Early Jurassic echinoid. There are at least 8 notable specimens between the plates, some having associated spines, as well as some smaller test fragments and some loose spines. These urchins are quite small, with the largest ones only being around 1cm (.3937 inches) in diameter.

    I fount this a few years ago around Livingston, New Jersey and do not quite know what it is. It is not completely symmetrical and does not quite match any of the other fossils that I have seen found in this area. I did see a Cycad fossil that had some resemblance but the less exposed side looks a little more different. It may also be a fish scale, tree bark, or even nothing. I think it is from the Towaco formation of the Lower Jurassic based on the location and the color of the rock. Any help would be greatly appreciated. Scale is in inches.

    The Tyrannosaur Dinosaurs (Tyrannosauroidea) inhabited North America from 152 Million Years ago during the Late Jurassic era up until 66 Million Years ago during the Late Cretaceous era. https://www.app.pan.pl/article/item/app20110141.html However, there is a relatively large geologic gap between the time of the Late Jurassic to the Santonian-Campanian stages of the Cretaceous (when the the oldest known Tyrannosaurid Lythronax (Late Creteaceous, 81.9-81.5 Million Years ago) emerged) in terms of the number of Tyrannosauroidae confirmed in North America. However, this doesn't mean they were completely absent from the Continent. Rather, they remained small to mid sized predators under the shadow of Large Carnosaurs up until the Cenomanian-Turnonian extinction event 93-94 Million years ago, which the tyrannosaurs filled the role of Apex Predator in most terrestrial ecosystems by the Campanian stage of the Cretaceous. The Tyrannosaur geologic gap between the Late Jurassic and Santonian Cretaceous is also not completely empty and several confirmed Tyrannosauroidea are known from this time period in North America. I've created a list of known Tyrannosauroidea species and specimens from the Aptian-Santonian Cretaceous of North America which I would like to share on the fourtm (let me know if there are any examples I'm missing or should add): Unnamed Cloverly Formation Tyrannosauroid (Tyrannosaur – Cloverly Formation, Wyoming, US, North America) (Early Cretaceous, 108 Million Years ago) (Based on Specimen FMNH PR 2750, likely grew up to 1.2 meters (3.9 feet) in length) https://www.tandfonline.com/doi/abs/10.1080/08912963.2010.543952 https://www.researchgate.net/profile/Lindsay- Zanno/publication/229287579_On_the_earliest_record_of_Cretaceous_tyrannosauroids_in_western_North_America_Implications_for_an_Early_Cretaceous_Laurasian_interchange_event/links/0fcfd50089dd8f3955000000/On-the-earliest-record-of-Cretaceous-tyrannosauroids-in-western-North-America-Implications-for-an-Early-Cretaceous-Laurasian-interchange-event.pdf Unnamed Wayan Formation Tyrannosauroid (Tyrannosaur – Wayan Formation, Idaho, US, North America) (Early Late Cretaceous, 100.6-97.8 Million Years ago) (Based on Specimen IMNH 2251/53975, grew up to 1.2 meters (3.9 feet) in length) https://bioone.org/journals/journal-of-paleontology/volume-96/issue-6/jpa.2022.42/A-partial-tyrannosauroid-femur-from-the-mid-Cretaceous-Wayan-Formation/10.1017/jpa.2022.42.full Unnamed Lewisville Formation Tyrannosauroid (Tyrannosaur - Woodbine Group Lewisville Formation, Texas US, North America) (Late Cretaceous (100-95 Million Years ago)) (Based on Specimens DMNH 2013-0701701 and SMU 77218, grew up to 2.7-4.8 meters (8.8-15 feet) in length) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8796713/ Moros intrepidus (Tyrannosaur – Cedar Mountain Formation, Utah, US, North America) (Early Cretaceous (96.4 Million Years ago)) (Grew up to 1.2 meters (3.9 feet) in length) https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6385174/ Suskityrannus hazelae (Tyrannosaur – Moreno Hill Formation, New Mexico, US, North America) (Early Cretaceous, 93.5-89.3 Million Years ago) (grew up to 3 meters (9.8 feet) in length) https://www.pure.ed.ac.uk/ws/files/82474043/82473554._Brusatte._AAM.pdf

    As a freshmen in College, I did a little extra credit report for my geology class about a controversial topic - Tyrannosauroidea diversity in the Southern Hemisphere during the Jurassic-Early Late Cretaceous periods. I was quite surprised at the amount of specimens I found. This diversity likely was the result of an early spread of the early tyrannosaur group Pantyrannosauria into Africa, Eurasia, and North America during the Jurassic and diversified once the land connecting these continents spread out more. Most of these species lived during the Early Cretaceous, though one or two exceptions might have lasted into the Early Late Cretaceous. I've created a list of known of the species and specimens which I would like to share on the forum (let me if there are any examples I'm missing or should add): South America Santanaraptor (Romualdo Member of the Santana Formation) (Early Albian, Cretaceous period 112.6-109.0 million years ago) Specimen: MN 4802-V (partial skeleton) http://www.fossilworks.org/cgi-bin/bridge.pl?a=collectionSearch&collection_no=67712 Tyrannosauroidea indet.

    Hi ! So I went on a walk in some marls in Lozère, France. Usually, I find some amonites and belemnites but this time I decided to change from my usual spot and searched around. I found an isolated marl which is a couple of kilometers away from the main marls which are known to be from the Toarcian. In the whole region (région des grands causses), marls can be either from Toarcian or Pliensbachian according to french wikipedia (https://fr.wikipedia.org/wiki/Marne_(géologie) ). Anyway in this new marl, I didn't find the same fossils as usual, at all. I found mainly gastropods, very small bivalves as well as some rare cases of amonites (which are abundant on the contrary on the other spot). So I was wondering what they were. I believe there are at least two different species in my findings : those on the upper lines look like some pictures of Amphitrochus pictures I found on this forum and on the net. On the second line are what I believe is a second species I didn't really manage to find similar thing on this forum. Under it I put the best looking very small bivalve I found in the very same marl. Do you know what could those be ? I hope it interests you ! Alice

    I'm not sure if I'm looking at a true fossil, or is this an impression of a modern day plant. As I often do, I washed the fossil down with warm water three times with the hope that if it was a modern imprint, it would partially, or completely fade away. Since it didn't fade one bit, I would like to please ask if these plant impressions are indeed legit fossils, or a stubborn modern day imprint. Early Jurassic, East Berlin Formation of Connecticut, USA. Thank you!

    Here are a few recent plant finds from the Early Jurassic East Berlin Formation in Hartford County, Connecticut. Possible plant ID's include Brachyphyllum/Pagiophyllum, Loperia simplex, Otozamites brevifolis. The most interesting fossil plate includes a marking that features three filamentous strands on one end, and a minute spore/seed head on the other. Comments, identifications, or corrections are greatly appreciated. Thank you!
  16. Cianfaglione
    The first time I found this type of triangular marking I thought it was a broken off tip of a much larger plant fossil. Five specimens later (all identical in size and shape including straight-edged base) and I'm now starting to think that this might be a possible pinnae to some sort of cycadophyte. Illustration from the book Introduction to Plant Fossils; Cleal and Thomas. Early Jurassic, East Berlin Formation of Connecticut. Thoughts and comments would be greatly appreciated.

    I found this interesting plate this morning, not sure what the two (circled) objects are, but they look like possible conifer cones, including what looks like a stem on the top cone-like marking. Early Jurassic, East Berlin Formation in Connecticut. Comments would be greatly appreciated. Thank you!

    Jurassic Trace Fossil

    Cianfaglione posted a topic in Fossil ID

    I'm still going through some of the rock that I collected from a road cut of the Early Jurassic East Berlin Formation (200 mya) in Connecticut. This caught my eye this afternoon, maybe a leaf?? It looks like a leaf from my ginkgo bonsai that I have sitting on my desk! Maybe its nothing. Thoughts and comments are greatly appreciated! Fossil is part and counterpart.

    Jurassic Trace Fossil

    Here is one more fossil plate (same location as previous post) that I found the other day along a road cut of the Early Jurassic East Berlin Formation (200 mya) in Connecticut. Maybe a horsetail and strobilus (bottom right corner)?? I don't know what the halo around the vertical lines are about. Thoughts and comments are again greatly appreciated. Thank you.
