Hikida - 2022.
Classification: Chordata, Dinosauria,
Saurischia, Theropoda, Therizinosauridae.
Species: P. japonicus
(type).
Diet: Herbivore.
Size: Uncertain due to lack of fossil remains.
Known locations: Japan - Osoushinai Formation.
Time period: Campanian of the Cretaceous.
Fossil representation: Partial post cranial remains
including bones from the hands, claws and a cervical (neck)
vertebra.
Fossils
of
this dinosaur were actually first mentioned in a scientific paper
published in 2008, but it would not be until 2022 that they
were formally described as a distinct genus. Paralitherizinosaurus is
a genus of therizinosaurid
dinosaur that lived in South East Asia
during the late Cretaceous. Although established upon the description
of just a few bone fossils, comparison to better preserved relative
genera allows us to infer that Paralitherizinosaurus was a bipedal
herbivore with very long claws on its hands. These claws may have
been aids to help Paralitherizinosaurus to feed.
