Perinates of a new species of Iguanodon (Ornithischia: Ornithopoda)
from the lower Barremian of Galve (Teruel, Spain).
Cretaceous Research 56: 250-264


We report 13 ornithopod perinates from the Lower Cretaceous of Spain.
These are a new species of Iguanodon, Iguanodon galvensis sp. nov.
Bone tissue reveals that they were in their first year of life.
Perinates were forming part of a group in the nesting vicinity when
they perished.


Although Iguanodon is one of the most abundant and well-known of
Europe's dinosaur genera, fossils of young specimens are very rare.
Indeed, the fossil record contains very few examples of the young of
any non-hadrosaurid iguanodontian. Here we report the discovery of 13
Iguanodon perinates from the Lower Cretaceous of Galve (Teruel,
Spain). The characteristics of an adult and juvenile found nearby show
these perinates to belong to a new species: Iguanodon galvensis sp.
nov. The histological and osteological features of these young animals
indicate them to have been in their first year of life. The taphonomic
features of their remains, plus the finding of clearly embryonic
vertebrae alongside them, suggest the perinates of this species
remained in the vicinity of their nests for some time, possibly
congregating in nursery areas.
