Definition of ultrasaurus in English:



  • A late Jurassic dinosaur related to brachiosaurus, known from only a few bones but probably the tallest ever animal, and possibly the heaviest at up to 130 tons.

    Genus Ultrasaurus, infraorder Sauropoda, order Saurischia

    • ‘Many of the sauropods are closely related and perhaps you are correct in thinking ultrasaurus is just a massive brachiosuar but this is doubtful.’
    • ‘But scientists have taken a second look and surmise that ultrasaurus could be the remains of a huge brachiosaur and supersaurus mixed together.’
    • ‘When I was about 5 I had a dinosaur book and there was a page with a silhouette drawing of a man standing beside an ultrasaurus leg.’
    • ‘All in all, I think it's easier to stick with ultrasaurus.’
    • ‘Jensen named the Ultrasaurus in 1985 (meaning "Ultra lizard").’


Modern Latin, from Latin ultra ‘beyond’ + Greek sauros ‘lizard’.
