What Is the Most Underrated Dinosaur?

  1. 1
    This dinosaur had long claws and was likely an herbivore, making it unique and fascinating.
    Therizinosaurus is a genus of theropod dinosaur that lived during the late Cretaceous period, around 70 million years ago.

    • Diet: It is believed to have been an herbivorous dinosaur, feeding on plant material such as leaves and fruits.
    • Bipedal: Despite its massive size, Therizinosaurus was a bipedal dinosaur, meaning it walked on two legs.
    • Feathered: Recent research suggests that Therizinosaurus may have been feathered, similar to other theropod dinosaurs.
  2. 2
    This dinosaur had a long, crocodile-like snout and was one of the few known piscivorous (fish-eating) dinosaurs.
  3. 3
    This dinosaur had long arms, which were once thought to be used for swimming. However, recent research has suggested they were used for gathering food.
