Anasazisaurus

In Depth        Anasazisaurus is currently only known from a single skull,‭ ‬but one that has a flange of bone rising from the top of its snout.‭ ‬Because this crest is solid,‭ ‬Anasazisaurus has been identified as a saurolophine hadrosaurid.‭ ‬The skull of Anasazisaurus was once attributed to the genus Kritosaurus,‭ ‬but because the skull contains … Read more

Atrociraptor

In Depth        Atrociraptor has been described from very incomplete remains,‭ ‬but two clear observations can be made about this dinosaur.‭ ‬One is that the snout appears to be both deeper and shorter than most other dromaeosaurs,‭ ‬something that could indicate a strong bite due to larger muscles and the outer teeth being placed closer to … Read more

Asiaceratops

In Depth        Very little‭ ‬is known about Asiaceratops because the currently known fossils of this dinosaur are so fragmentary that some researchers have even questioned the validity of the genus.

Samrukia

In Depth        Samrukia is a genus that illustrated the dangers of naming prehistoric creatures by only partial remains.‭ ‬The original describers of Samrukia‭ (‬Naish et al.‭) ‬had a single jawbone that was first thought to belong to an ovirapotosaurian theropod dinosaur,‭ ‬but then later thought to belong to a bird.‭ ‬This raised a lot of … Read more

Labidosaurikos

In Depth        Labidosaurikos should not be confused with the similarly named Labidosaurus,‭ ‬another captorhinid that lived in the same approximate locations as Labidosaurikos.‭ ‬In fact the name Labidosaurikos means‭ ‘‬similar to Labisosaurus‭‘‬.‭ ‬Labidosaurikos seems to have been a bit larger and heavier than its relative,‭ ‬and is noted for having a robust and fairly ornate … Read more

Arenysuchus

In Depth        A member of the Crocodyloidea which includes surviving modern species,‭ ‬Arenysuchus is still regarded as a more basal form due to the frontal skull bones contacting the fenestra‭ (‬openings‭) ‬on top of the skull.‭ ‬At the time of writing only a partial skull of Arenysuchus is known,‭ ‬but at just under twenty centimetres … Read more

Minmi

minmi

In Depth        Well preserved dinosaur remains are rare from Australia,‭ ‬but Minmi is one of the exceptions.‭ ‬This‭ ‬is‭ ‬in part due to the small body size of Minmi which meant that it would have been‭ ‬more‭ ‬easily buried than a larger animal,‭ ‬something that would have protected the remains from being scattered by scavengers … Read more

Megalancosaurus

In Depth        Megalancosaurus is one of the better known of the‭ ‬drepanosaurs,‭ ‬a special group of reptiles that possessed tails that could hook around branches.‭ ‬With an additional hook on the end of their tails,‭ ‬Megalancosaurus are believed to have walked along the‭ ‬branches of Triassic era tree canopies,‭ ‬hunting for small invertebrates to eat. … Read more

Brontochelys

In Depth        Originally named as a species of Shweboemys,‭ ‬Brontochelys is a little known genus of side-necked turtle that lived in Pakistan during the early Miocene.‭ ‬The type species is named in honour of Eugene Gaffney for his work on turtles.

Kol

In Depth        So far at the time of writing the only known fossils of Kol are of a complete foot.‭ ‬This foot however is enough to identify Kol as an alvarezsaurid dinosaur,‭ ‬and one that was fairly big.‭ ‬The foot of the Kol holotype specimen is about twice the size of the foot of Shuvuuia,‭ … Read more
