A small ornithopod
dinosaur, Valdosaurus had a gazelle-like lifestyle,
feeding on the ferns and cycads, running away when attacked by predators.
It was not always successful at this, as one specimen was found
in association with Eotyrannus
teeth and bones.

body of Valdosaurus's ilium is low, with a wide brevis shelf,
and the obturator process of the ischium is placed proximally. The
femur has a pendant fourth trochanter well on the proximal half
of the shaft, a deep pit medial to the fourth trochanter set well
anteriorly to the shaft, a rod-like lesser trochanter separated
by a deep grove from the greater trochanter, the distal end has
sub-square medial edges and a deep anterior intercondylar groove
that may be partly overhung laterally. The dentary has 15 teeth.
The teeth are similar to those of Iguanodon,
but are less leaf shaped.
very similar to Hypsilophodon
and Iguanodon, but can be distinguished
from them as it has a curved femur, whereas Iguanodon
and Hypsilophodon have straight
femur shafts. The cleft separating the anterior trochanter from
the greater trochanter is deeper than it is in either Iguanodon
or Hypsilophodon. The fourth
trochanter is more proximally situated than in Iguanodon.
It had a shorter pes than Hypsilophodon,
and only three functional toes.

do I know if I've found a bone?
