Ultrasaurus was a massive plant-eater (herbivore) that lived in the late
Cretaceous period,
between about
110 and 100 million years ago, in what is today
Korea.
Ultrasaurus was discovered by
Haang Mook Kim in
1983.
He named his discovery "Ultrasaurus" because he believed it was a
relative of a dinosaur previously found by Jim Jensen in the
US in
1979
(Jensen had used the name "Ultrasaurus" only unofficially at this point to
describe his dinosaur). However, since
Haang Mook Kim was officially the first to use the name "Ultrasaurus",
this name could not be used for Jensen's dinosaur
(Jensen's dinosaur was for a time known as "Ultrasauros" -
note an "o" instead of the final
"u" - but Ultrasauros later turned out to be a mix
of
Supersaurus and
Brachiosaurus
fossils).
Not too much is known about Ultrasaurus, because of the very limited number
of fossils yet found. As a result,
it is not known which Family it belongs to, and some argue that it is even possible that the
fossils may simply be from a previously
known species. As a result, Ultrasaurus is considered by some to be a
"nomen dubium"
(a scientific name of unknown or doubtful application).
Ultrasaurus was a herbivore (plant-eater) that lived from 110 to 100 million years ago

Ultrasaurus is considered by some to be a "nomen dubium" (a scientific name of unknown or doubtful application) - because only a few fossils have been found, and it is uncertain which Family to assign the animal to (it is even possible that the fossils may be from a previously known dinosaur).
