Brachytrachelopan is a short-necked sauropod dinosaur found in the Late Jurassic (Oxfordian to Tithonian) of Argentina. The only known holotype specimen (Museo Paleontologico Egidio Ferruglio MPEF-PV 1716) was found in an erosional exposed of fluvial sandstones within the Canadon Calcareo Formation on a hill that is approximately 25 km (16 miles) northeast in Cerro Condor, Chubut Province located located in western-central Argentina, South America. Although it is a bit incomplete the skeletal pieces that were found were found in articulation . They comprised of eight cervical, twelve dorsal and 3 sacral vertebrae and proximal parts of the cervical ribs posterior as well as all dorsal ribs as well as the distal edge of the left femur the proximal portion of the left tibia along with an ilium on the right. A large portion of the specimen may have been lost to erosion for many years before it was discovered. The species of interest can be described as Brachytrachelopan mesai. The name is a tribute to Daniel Mesa, a local shepherd who stumbled upon the specimen while looking to find lost sheep. The genus name is translated as “short-necked Pan”, Pan is the god of shepherds.

The taxon’s extremely short neck (approximately 40 percent shorter than other dicraeosaurids ) and its shortest neck (of any sauropod known) is proof that this lineage was specialized to fill a niche in the ecology not being exploited by the other members of the infraorder. It was small for a sauropod. Brachytrachelopan was less than 10 meters (33 feet) long. Rauhut et al. (2005 670) highlight the degree of fusion that exists between the neural arches that are preserved and their respective centrala and also the fusion between the sacral central region and sacral neural arches as well as sacral neural spines, is proof that the holotype does not represent an animal that is young. Therefore, the body’s small size is not a remnant of ontogeny.
