Name:
Thalassodromeus
(Sea runner).
Phonetic: Fah-lass-oh-dro-meus.
Named By: Kellner & Campos - 2002.
Classification: Chordata, Reptilia, Pterosauria,
Pterodactyloidea, Neoazhdarchia. Thalassodromidae.
Species: T. sethi (type).
Type: Piscivore/Carnivore.
Size: Typically 4.5 meter wingspan, larger
individuals possibly up to 5.3 meter wingspan.
Known locations: Brazil - Santana Formation.
Time period: Albian of the Cretaceous.
Fossil representation: Two specimens.
The
most striking feature of Thalassodromeus is the
highly ornate head
crest, one of the largest known among pterosaurs.
From the side this
crest resembles the pharaoh crown that is often depicted in artwork of
ancient Egyptian gods. It is for this reason that the type species is
named T. sethi, after the god Seth, although it
seems that the
describers confused a picture of Seth with that of the god Amun.
Thalassodromeus
was first thought to be similar to Tapejara,
however current thinking
has Thalassodromeus being similar to Tupuxuara
and closer to the
azdarchid line of pterosaurs. Widely accepted depictions of this group
have them stalking on the ground like Storks do today rather than
feeding on the wing. If correct then Thalassodromeus
may have either
stalked across the land looking for things like lizards, or remained on
the water’s edge in the shallows hunting for fish and amphibians like
Herons do today.
