Resumen:
The Esqueda locality is well known for its quarries, which provide
shales that are used for construction and that also contain dinosaur
ichnites. This study determines the age of the shale deposits. A late
Campanian age is suggested for the uppermost part of the Cabullona Group
for the whole Esqueda section, based on palynological assemblages and
U-Pb geochronology.
