Rhomaleopakhus (meaning "strong forearm") is a genus of mamenchisaurid sauropod, dinosaur from the Late Jurassic Kalaza Formation of China. The type and only species is Rhomaleopakhus turpanensis.[1]
History
The
Turpan Basin where the specimen was collected.[1]
Description
Upchurch et al. note that the robustness of the forelimb, after which the taxon was named,
ceratopsids. They believe this correlates with a more flexed orientation of the forearm, an enhanced role of the forearm in feeding, and a more anterior shift in the center of mass. It is possible that CMTs and titanosaurs specialized in a feeding strategy that involved efficient locomotion between sparsely-located food sources.[1]
Classification
Upchurch et al. used Moore et al. (2020)'s[4] phylogenetic analysis to determine the relationships of Rhomaleopakhus. They found it to be a mamenchisaurid sister to Chuanjiesaurus, in a clade that also includes Analong. Their cladogram is shown below:[1]
