Palaeobotanical remains associated with dinosaur fossils from the
Camarillas Formation (Barremian) of Galve (Teruel, Spain).
Historical Biology (advance online publication)

A well-preserved macroflora and rich palynological assemblages
corresponding to the Camarillas Formation (early-middle Barremian) in
the San Cristóbal and Galve Mine sites from the Galve sub-basin in
northeastern Spain are presented here. These remains represent the
first fossil plant evidence from these deposits. Within plant
macroremains, the cheirolepidiacean Pseudofrenelopsis aff. varians
(Fontaine) Watson has been found. The palynological assemblage yielded
well-preserved spores and pollen grains, mainly dominated by the genus
Classopollis. Spores are also abundantly represented by schizaeacean
spores (Cicatricosisporites and Plicatella). This spore assemblage
supports an early-middle Barremian age for these localities. It is
noteworthy that small basal angiosperm pollen grains of the genera
Crassipollis and Retimonocolpites, together with other indeterminate
grains, have been reported here. This flora constitutes the primary
food producer for dinosaur at that time, and thus the information of
the flora is important for the understanding of the ecological
background for the dinosaur evolution during the Early Cretaceous.
