Ikrandraco

Ikrandraco avatar, a pterosaur from the Early Cretaceous of China (~120 mya). Although it was close relative of the well-known Pteranodon it was much smaller, with an estimated wingspan of around 1.5m (4′11) – similar in size to a large seagull.

Its name was based on the fictional ikran creatures from the 2009 movie Avatar, in reference to similarity of the the large crests on their lower jaws.

A hook-shaped projection at the back of the crest may have been an attachment point for a pelican-like throat pouch. The paleontologists who described Ikrandraco also suggested that its crest could have been used for skim-feeding, although this is a highly controversial idea among pterosaur specialists.

Zuul

Zuul crurivastator, an ankylosaur from the Late Cretaceous of Montana, USA (~75 mya).

One of the most complete ankylosaurids ever found in North America, it’s known from a full skeleton about 6m long (20′). Much of its bony osteoderm armor is preserved in life position, along with skin impressions and the remains of keratinous scales and spike sheaths – although so far only the skull and tail have actually been fully prepared and described.

(The fuzz on this reconstruction is highly speculative, but since it’ll likely end up inaccurate anyway once of the rest of the body is fully described… why not have some fun with it?)

Its genus name was inspired by its skull’s resemblance to Zuul the Gatekeeper from the 1984 movie Ghostbusters, while its species name translates to “destroyer of shins” in reference to its especially large tail club.

Eucritta

Eucritta melanolimnetes, an amphibian-like creature from the Early Carboniferous of Scotland (~335 mya). About 25cm long (10″), it had a mixture of anatomical characteristics similar to baphetid stem-tetrapods, temnospondyls, and reptile-like amphibians, making its exact classification difficult. It’s currently considered to be a close relative of both the baphetids and Crassigyrinus, and it was probably close in appearance to what the common ancestor of all later tetrapods would have looked like.

Its name means “true creature from the black lagoon”, in homage to the 1954 monster movie.
