Named By: Sterling J. Nesbitt, Julia A. Clarke, Alan H. Turner and Mark A. Norell - 2011.
Classification: Chordata, Reptilia, Dinosauria, Saurischia, Theropoda, Maniraptora, Alvarezsauridae, Parvicursorinae, Ceratonykini.
Species: A. baatar (type).
Size: Uncertain due to lack of remains, but estimated to be about 1kg in weight.
Known locations: Mongolia - Javkhlant Formation.
Time period: Santonian of the Cretaceous.
Fossil representation: Pelvis and hind limbs (IGM 100/3004).
one of the notable things about Albinykus is that
even though it is only known by its hind quarters, these were found
in a crouching position. Oviraptosaurs
are also known
to have crouched, so the discovery that alvarezsaurs like Albinykus
could also enter this position indicates that crouching in at least
some theropod (mostly maniraptorian) dinosaurs was fairly common.
Unfortunately the lack of further skeletal and cranial remains means that there is still much we don’t know about this genus, but as an alvarezsaur, Albinykus would be expected to have very short stubby arms, possibly ending in just a single claw, while possibly being insectivorous in its dietary habits. While the exact size of Albinykus is unknown, the remains of the holotype indicate that this was one of the smallest alvaresaurs so far discovered.
