  1. Earliest Dinosaur Eggs Studied

    New publication on the structure and evolutionary implications of the earliest (Sinemurian, Early Jurassic) dinosaur eggs and eggshells. https://www.nature.com/articles/s41598-019-40604-8?fbclid=IwAR1YN8f-qfgAjeFHRGIa0pAWfac6KRskDk73jyar2PZ6OcRk8XccNMXn_po Photos provided by D Evans of Massospondylus egg nest with embryos @-Andy- @HamptonsDoc
  2. The theropod informally called "Saltriosaurus" is finally published after so many years as a nomen nudum: The following link is available here: Dal Sasso C, Maganuco S, Cau A. 2018. The oldest ceratosaurian (Dinosauria: Theropoda), from the Lower Jurassic of Italy, sheds light on the evolution of the three-fingered hand of birds. PeerJ 6:e5976 https://doi.org/10.7717/peerj.5976 Although Scipionyx interested me as the first dinosaur found in Italy (it happens to be named after the Roman general Scipio Africanus, who defeated Hannibal at the Battle of Zama in 202 BCE in Tunisia, ending the Second Punic War), I first heard of the dinosaur now called "Saltriosaurus" while reading the book Scholastic Dinosaurs A To Z back in 2003, but what was informally dubbed "Saltriosaurus" is now called Saltriovenator, and after being initially considered a tetanuran, it is apparently an early ceratosaur.

  5. Hello, this is a part 2 of my last thread with some of my other finds that I've found this at a site in new jersey where some footprints have been found from the Late Triassic/Early Jurassic, I am unsure about if these are footprints of sorts, any help will be appreciated thank you!

  8. Steneosaurus sp. (St.Hilaire 1825)

    11 mm. long tooth. Missing the point again Recieved on a trade for prep with Sebastian (belemniten). From the slate quarry Kromer in Oehmden near Holzmaden. Early Jurassic, early Toarcian Posidonienschiefer, "Schlacken".
  9. Ichthyosaurus (Koenig 1816)

  10. Scanning a small coprolite from Lyme Regis, UK, I noticed this little button-shaped inclusion. I was just wondering if anyone recognized what this might be. My only guess would be an otolith. Any ideas? I'm tempted to try to remove it to get a good look at the other side. Thanks for looking!
  11. Coprolite?

    Hello everyone, Today I was going through all my older fossils, and I found this in my box of ammonites. Obviously this isn't one, and I must have put it in that box by mistake. It looks a lot like a coprolite to me, but I have no clue from what animal. Unfortunately I don't remember anymore where I found it. There are two possibilities: either from Lyme Regis (UK), or from one of the Cretaceous beaches on the Isle of Wight. Any clue to what it could be, and maybe what location? Best regards, Max
  12. Fish tail or more likely shell?

    Hi all, Maybe this find is past identification due to erosion, but i thought it may be of interest to others Length is around 8 inches I can see similar lines to the shell / tail feature on the right of the 'solid' part.. Wondering if anyone has any idea what it might be? is it two separate fossils perhaps? All the best Ben

  15. Coelacanth Scales and Bones

    From the album Fossildude's Jurassic Fish Fossils

    Scales and bones of an Early Jurassic coelacanth, Diplurus longicaudatus. Shuttle Meadow Formation, Hartford Basin, Connecticut. Found on 11/14/2016. This is the rarest fish to find in the Hartford Basin. Even small bits of these are few and very far between.

  16. Well preserved with shell.
  17. Semionotus sp. Part and Counterpart

    Partial Semionotus sp. - part and counterpart. Nearly complete - missing caudal fin. Species indeterminate - possibly S. micropterus? Early Jurassic, Shuttle Meadow Formation. Connecticut.
  18. I'm a huge fan of the 'abelisaurids' and while searching for any news on the lumbering predators I found this report on the new genus 'eoabelisaurus'. It shows a lot of features of late Cretaceous abelisaurs, despite coming from the early Jurassic, before the likes of allosaurus. Enjoy! http://blog.everythingdinosaur.co.uk/blog/_archives/2012/06/04/new-species-of-abelisaurid-described.html
  19. New Species Of British Ichthyosaur

    A new ichthyosaur known as Wahlisaurus has been identified from a museum specimen found in an English quarry more than 60 years ago. This is the first known Early Jurassic ichthyosaur known from England since 1986. Original paper: http://www.tandfonline.com/doi/full/10.1080/14772019.2016.1183149 Simplified: http://www.sci-news.com/paleontology/wahlisaurus-massarae-new-species-dolphin-like-reptile-03947.html
  20. Hi All, I have a new coprolite from the Black Ven area near Lyme Regis. It has what looks like undigested cephalopod beak inclusions. Can anyone out there confirm this for me? On the back side, it looks like a section through a belemnite cone, but I'm not seeing any hooks. There is also another inclusion that I can't quite figure out.
  21. A new paper regarding a new primitive Early Jurassic theropod from the Lufeng Basin of China is out: Hai-Lu You, Yoichi Azuma, Tao Wang, Ya-Ming Wang and Zhi-Ming (2014). "The first well-preserved coelophysoid theropod dinosaur from Asia". Zootaxa 3873 (3): 233–249. doi:10.11646/zootaxa.3873.3.3. Coming upon the heels of another basal theropod, Tachiraptor, Panguraptor represents the second basal theropod from the Lufeng basin (the first being Sinosaurus). Since China was so far apart from other continents yielding Early Jurassic theropods (Africa, North America, South America, India), more research is needed to determine how Early Jurassic theropods made it to China from Gondwana.
  22. More fish

    From the album Fossildude's Jurassic Fish Fossils

    3/4 fish, Redfieldius gracilis, head should be there under the shale. Should prep out well. From the Early Jurassic, Shuttle Meadow Foramtion Connecticut.

  23. Headless, Tail-less Fish

    From the album Fossildude's Jurassic Fish Fossils

    Redfielidius gracilis missing head and tail. Early Jurassic, Shuttle Meadow Formation. Connecticut.

  24. Semionotus tenuiceps

    From the album Fossildude's Jurassic Fish Fossils

    Front half of the early Neopterygian fish Semionotus tenuiceps from the early Jurassic (Hettangian)Shuttle Meadow Formation of Connecticut. This fish needs some prep, but appears to have the entire skull present. This is identified as an S. tenuiceps by the large "hump" directly behind the skull. I believe this is the only identifiable example of this fish in my collection.

  25. Semionotus tail and fins

    From the album Fossildude's Jurassic Fish Fossils

    Partial back end of a Semionotus sp. Caudal, dorsal, anal, and pelvic fins are present. Early Jurassic, (Hettangian) Shuttle Meadow Formation. Connecticut. Also, note the Otozamites brevifolis pinnule, and the Diplurus longicaudatus coprolite just above the tail.
