Summary
| Description |
English: Life restoration of the Late Turonian russellosaurine Yaguarasaurus columbianus (Páramo, 1994) from the upper Magdalena River Valley in Colombia, hypothetically depicted as a tethysaur.
Reference: Head is informed by holotype BRV-68 (Páramo, 1994) and referred specimen MP-14 (Páramo-Fonseca, 2000). Appendicular skeleton follows the yaguarasaurine hypothesis that Yaguarasaurus and tethysaurines form an early-diverging clade per Palci et al. (2013). It is likewise plesiopedal and plesiopelvic as inferred from Tethysaurus and Pannoniasaurus. Postcranial body proportions are based on Platecarpus skeleton LACM 128319 (Lindgren et al., 2010). This was chosen as an estimation of similar ecology, as Y. columbianus is recovered from a marine platform environment and about the same size as Platecarpus. Tail is speculative. |
