As an ichnogenus, the taxon is represented by (and named for) a 90-metre (295 ft) long series of fossil tracks, or ichnites, found in the spring of 1979 in the Atlas Mountains of present-day Morocco.

The animal that produced the Breviparopus tracks is rumored to be one of the largest dinosaurs, though its exact size has been the subject of much debate.

[1][7] In 2020 Molina-Pérez and Larramendi suggested that the narrow-gauge track, the position of the claws, and the era all indicate that it belonged to an enormous diplodocoid, and estimated its size at 33.5 m (110 ft) and 62 t (68 short tons).

Since no actual bones of Breviparopus have been identified, it is difficult to say with certainty whether the tracks were made by a diplodocid, titanosaur or brachiosaur.

[9] However, the presence of a small medially directed thumb-claw print[5][10] makes it likely the animal was a brachiosaur, since they have small thumb claws at ground level (as opposed to diplodocids and camarasaurids, whose thumb metacarpals are short and hold their thumb claws off the ground), and the narrow-gauge stance also fits with a brachiosaur body shape - in the Early Cretaceous, the dominant sauropods were wide-bodied titanosaurs, and deep-bodied brachiosaurs which had more narrowly spaced legs - therefore the narrow gauge of the Breviparopus prints favors a brachiosaurid diagnosis (this seems to be corroborated by the sacrum of Brachiosaurus nougaredi, which is unusually narrow for its length even by brachiosaur standards).
