It probably spent most of its time on all fours, though, only moving bipedally when it needed to run rapidly.

Its skull also resembled those of theropod dinosaurs, but its more primitive features included the presence of five toes on each foot and a double row of armoured plates along the animal's back.

[3] "Dasygnathus" longidens was in 1877 created by Thomas Huxley for a right maxilla from the Lossiemouth Sandstone found in 1857.

The genus name Dasygnathus had already been used for a coleopteran insect, so Huxley's generic name was in 1961 changed to Dasygnathoides.

Although synonymized with Ornithosuchus by Walker (1964), a 2016 study found Dasygnathoides indeterminate beyond Pseudosuchia.
