was a two meter long reptile that had an elongated body that was
protected by a covering of bony scutes in a similar manner to a
crocodile. Doswellia had a triangular shaped
skull when viewed from
above, the snout being much narrower than the posterior regions of
the skull. The skull of Doswellia also identifies
it as a euryapsid,
a member of the Euryapsida, a group of reptiles similar to
diapsids, but where the lower temporal fenestra has closed in on
itself. These reptiles became quite common in the past with members
including plesiosaurs and the placodonts, though today there are no
known surviving members of this group. Doswellia
has in the past been
considered as uncertain in its ecological role, though it has often
been mentioned as a predator of small animals. The narrow snout of
Doswellia would have been of particular use for
reaching into crevices
to pluck out hiding prey.
Doswellia is the type genus of the Doswelliidae, a group of archosauriforms that also includes Archeopelta and Tarjadia.
