"It can now provide us with a better picture of the starting point for the changes between bipedal and quadrupedal
ceratopsians," adds Morschhauser.
The geological age of the new whale, its place of discovery, and its affinities with more fragmentarily known quadrupedal
whale remains from the west coast of Africa also support the hypothesis that amphibious whales crossed the South Atlantic to reach South America, before a northward dispersal along the east coast of the US, according to Lambert.
The BBB rating score is composed of 22 nonlinear operational definitions (0-21 scale) studying several aspects involved in the locomotion of quadrupedal
animals such as weight support, plantar stepping, and forelimb/hindlimb coordination.
It includes running, climbing, swinging, vaulting, jumping, rolling, quadrupedal
movement, and is said to have some aspects of a non-combative martial art.

In a close encounter with a sheep, for example, Isserley comments on the "human" appearance of the animal (the aliens, we learn, are quadrupedal
and covered in fur): "It was so hard to believe the creature [the sheep] couldn't speak.
They possessed some adaptations for aquatic life, but many remained quadrupedal
with the ability to locomote on land.
It is usually through running, jumping, climbing and quadrupedal

This is embedded in the very history of dinosaur fossils, as in Gideon Mantell's historic discovery of the iguanodon, which switched between bipedal and quadrupedal
before being, ultimately, classified as both--a complicated history muddied further by early palaeontologists' tendency to throw ambiguous fossil discoveries under the 'iguanodon' banner.
