Map of the Turonian world with occurrences of the ammonite Pseudaspidoceras flexuosum, shown in the lower right (scale 10 cm). The location of Vallecillo and the occurrence of this species in Texas are marked by larger dots because this seems to have been its main occurrence with the longest record. Map based on 95 Ma map of Blakey (2012), modified after Ifrim (2013)
