Abstract
This contribution presents the partial results of an
investigation plan of a reptile teeth set, collected
from one of the richest and most diversified fossil deposits from the middle
Cretaceous from the State
of Maranhão, Brazil: the Laje do Coringa. Situated in the Cajual Island,
Alcântara Municipality, it consists of
bone-bed with an expressive fossil record, late Albian/early Cenomanian in
age, belonging to the Alcântara
Formation, São Luís-Grajaú Basin. Analysis of morphologic parameters of
teeth crown suggests an association
of at least four morphotypes to Ornithocheiroidea pterosaurs. Based on this
interpretation, this group, which
has a diversified record in the middle Cretaceous deposits from the Santana
Formation, Araripe Basin, has now
its first occurrence demonstrated in the São Luís-Grajaú Basin.
