    The dinosaur of the day: Cryptosaurus

    • Ankylosaur that lived within the Late Jurassic in what’s now England (Ampthill Clay Formation, in Cambridgeshire)
    • Doubtful genus, as a result of solely recognized from a partial femur
    • Femur is thick / stout and about 13 in (33 cm) lengthy
    • Femur belonged to a subadult or grownup
    • Herbivorous
    • Sort and solely species is Cryptosaurus eumerus
    • Genus identify means “hidden lizard”
    • Genus identify refers to it being a uncommon discover (first one discovered within the Oxford Clay, although later it was decided to be from Ampthill Clay Formation)
    • Species identify means “well-formed thigh” in Greek
    • Discovered a partial proper femur in 1869, discovered by geologist Lucas Ewbank, who donated it to the Woodwardian Museum at Cambridge
    • Harry Seeley named Cryptosaurus in 1869
    • Seely’s description was temporary: “On Shelf g is briefly positioned the femur of a Dinosaur from the Oxford Clay, Cryptosaurus eumerus”
    • Seeley gave a full description in 1875
    • Seeley thought it was an animal “of sluggish habits” and will have been cold-blooded
    • Seeley thought Cryptosaurus was associated to Iguanodon, and later, in 1909, Friedrich von Huene categorized it as Camptosauridae
    • In 1980, Peter Galton discovered Cryptosaurus to be an ankylosaur
    • Galton discovered the femur of Cryptodraco was similar to the femur of Hoplitosaurus
    • Galton wrote that the identify Cryptodraco / Cryptosaurus “has turned out to be extraordinarily applicable as a result of it took over 110 years for the ankylosaurian affinities of this femur to be acknowledged.”
    • Richard Lydekker renamed Cryptosaurus in 1889 to Cryptodraco as a result of he thought Cryptosaurus was already used to call a crocodyliform in 1832. Seems this was an error, and as a result of mistaken spelling the crocodyliform was Cystosaurus. So the identify Cryptosaurus might stay for the dinosaur
    • For some purpose Lydekker stated that it was unknown the place the femur was discovered, although Seeley described the locality (the Oxford Clay)
    • Galton wrote that the femur was discovered with 17 related Pliosaurus vertebrae, and subsequently the femur “should have come from a brick pit fairly than as an remoted bone from a conglomerate”
    • Galton recommended the ancestors of Cryptosaurus have been most likely bipedal ornithopods, however that Cryptosaurus could have been facultatively bipedal (usually on all fours however might go on two legs when vital)

    Enjoyable Reality:
    For ~140 Million years (at the very least all the Jurassic & the Cretaceous) each terrestrial megaherbivore on Earth was a dinosaur.
