Ruflorinia is a genus of fossilized foliage from the Early Cretaceous of Argentina assigned to the order Caytoniales. ^[2]

Taxonomy

The genus was first established by Sergio Archangelsky based on material from the Anfiteatro de Ticó Formation, Santa Cruz, Argentina, with the type species being Ruflorinia sierra. ^[1] The genus name celebrated the Swedish paleobotanist Rudolf Florin. Other two species (R. pilifera and R. papillosa) were later described from the Anfiteatro de Ticó ^[3] and another (R.orlandoi) was later described from the Springhill Formation in Argentina. ^[4]

Paleoecology

In the Anfiteatro de Ticó Formation, leaves of this genus are found in association with the ovulate organ Ktalenia, and the conifer Brachyphyllum , and the foliage of Mesodescolea . The depositional environment is characterized by river deposits, and the fossils show little evidence of transport. ^[5]
