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.
