[1] In 2023, Farlowichnus rapidus was described by Giuseppe Leonardi, Marcelo A. Fernandes, Ismar S. Carvalho, Julia B. Schutzer, and Rafael C. da Silva as a new ichnogenus and ichnospecies of theropod footprints based on these fossil remains.

The generic name, "Farlowichnus", combines a reference to James O. Farlow, a paleontologist who has studied ichnofossils, with the Greek "ίχνος" ("ichnos"), meaning "track".

[1] The dinosaur trackmaker of the Farlowichnus footprints may have reached lengths of up to 3–3.5 metres (9.8–11.5 ft), as indicated by the larger size of one of the paratype specimens.

[1][2] However, Navarro et al. (2025) questioned the noasaurid interpretation for the trackmaker of Farlowichnus due to the difference in pedal and ungual anatomy compared to those of Vespersaurus.

Fossil remains of several indeterminate animals, including theropod and large ornithopod dinosaurs, mammals, lacertilian reptiles, and invertebrates, have also been described from the formation.
