    • Had almond formed tooth
    • Enamel on tooth had a wrinkled sample
    • Cabrera described the tooth as similar to Brontosaurus tooth, however narrower and about 50% bigger (although he stated Amygdalodon was a lot smaller than Brontosaurus, so proportionally its tooth have been stronger)
    • One of many tooth was discovered implanted within the alveolus
    • Sort species is Amygdalodon patagonicus
    • Genus identify means “almond tooth”

    • Holotype consists of vertebrae, ribs, 4 full tooth, three partial tooth, partial pelvis and shoulder-blade
    • Described by Ángel Cabrera, head of the Division of Vertebrate Paleontology on the Museo de La Plata, in 1947
    • Alejandro Piatnitzky had talked about in 1936 “bones of a saurian of a minimum of 5-7m lengthy” in deposits in Chubut, and in 1947 Dr. Tómas Suero confirmed the fossils and excavated them
    • Fossils have been discovered “in a mattress of sandy tuff and bluish grey clay”
    • Rodolfo Casamiquela redescribed Amygdalodon in 1963 and located that fossils Suero discovered in addition to different fossils beforehand discovered by Piatnitzky belonged to Amygdalodon
    • In 2003, Oliver Rauhut revised Amygdalodon and located that the fossils described belonged to not less than two people, and that a few of these fossils might belong to a distinct species (although they might additionally present totally different ages of the identical species). Made an anterior dorsal vertebra the lectotype, and stated solely three vertebrae have been positively Amygdalodon (additionally the tooth?), and the remaining have been indeterminate Eusauropod materials

    Enjoyable Truth:
    The large head crests on Parasaurolophus & Tlatolophus are fashioned by a massively prolonged premaxilla throughout the highest of their heads.
