Figure 6. Character attribution for the 96 in A phylogenetic analysis of Diplodocoidea (Saurischia: Sauropoda)

open access: yes, 2011
Figure 6. Character attribution for the 96 pooled relevant characters. Notice the predominance of two analyses (Wilson, 2002; Upchurch et al., 2004), both of which predate the description of many problematic taxa, and neither of which presents data that ...

The origin of an invasive air sac system in sauropodomorph dinosaurs

open access: yesThe Anatomical Record, Volume 307, Issue 4, Page 1084-1092, April 2024.
Abstract One of the most remarkable features in sauropod dinosaurs relates to their pneumatized skeletons permeated by a bird‐like air sac system. Many studies described the late evolution and diversification of this trait in mid to late Mesozoic forms but few focused on the origin of the invasive respiratory diverticula in sauropodomorphs. Fortunately,

The effect of intervertebral cartilage on neutral posture and range of motion in the necks of sauropod dinosaurs [PDF]

open access: yes, 2013
The necks of sauropod dinosaurs were a key factor in their evolution. The habitual posture and range of motion of these necks has been controversial, and computer-aided studies have argued for an obligatory sub-horizontal pose.

A proxy for brain‐to‐endocranial cavity index in non‐neornithean dinosaurs and other extinct archosaurs

open access: yesJournal of Comparative Neurology, Volume 532, Issue 3, March 2024.
Illustration of the endocranial doming, which can provide a proxy for the brain‐to‐endocranial cavity index, using the endocast of an adult of the iguanodont dinosaur Proa valdearinnoensis as an example. Abstract Although the brain fills nearly the entire cranial cavity in birds, it can occupy a small portion of it in crocodilians.

Figure 9 in A phylogenetic analysis of Diplodocoidea (Saurischia: Sauropoda)

open access: yes, 2011
Figure 9. Calibrated phylogeny of diplodocoid sauropods. Cross-hatched bars indicate Gondwanan affinities, hollow bars indicate Laurasian. Grey bars indicate 'old world' (Europe/Africa), white bars indicate 'new world' (North/South America).

Osteology of Huabeisaurus allocotus (Sauropoda: Titanosauriformes) from the Upper Cretaceous of China

open access: yesPLoS ONE, 2013
The Late Cretaceous titanosauriform sauropod Huabeisaurus allocotus Pang and Cheng is known from teeth and much of the postcranial skeleton. Its completeness makes it an important taxon for integrating and interpreting anatomical observations from more fragmentary Cretaceous East Asian sauropods and for understanding titanosauriform evolution in ...
