Breviparopus
''Breviparopus'' (ichnotype ''B. taghbaloutensis'') is the name given to an ichnogenus of dinosaur, having been made by an unknown genus of sauropod. 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. At the time, this area would have been part of the splitting Gondwana supercontinent.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.〔http://svpow.wordpress.com/2009/10/13/how-big-were-the-biggest-sauropod-trackmakers/Sauropod Vertebra Picture of the Week: How big were the Biggest Sauropod Trackmakers?〕
==Fossil material and age==
The combined length of the tracks of the foot and hand measured , and they were in width. They are commonly dated to the Jurassic period (approximately 160–175 million years ago), though they are more likely from the early Cretaceous, roughly 130-120 million years ago. They were first described by Jean-Michel Dutuit and Achmed Ouazzou in 1980.〔Dutuit, J.M. & A. Ouazzou (1980).
