“…), because it possessed 'paravertebrae', including ossified aponeuroses and ossified tendons (Molnar 1996). This specimen has received substantial attention (Molnar & Clifford 2000;Molnar 2001;Leahey et al 2008;Leahey et al 2010), although it still awaits a detailed description of its cranial and postcranial anatomy. QM F18101 is also from a somewhat younger formation compared to the holotype of Minmi paravertebra, and so a new generic name is probably warranted for this exceptional and important Australian dinosaur specimen.…”

“…Finally, several sauropod taxa are now 308 known to possess a deep fossa [centrodiapophyseal fossa sensu Wilson et al (2011b)] like 309 that seen on Longman's "specimen A" between the "prezygapophyseal lamina" [= anterior 310 centroparapophyseal lamina (ACPL)] and the "infradiapophysial buttress" [= posterior 311 centrodiapophyseal lamina (PCDL)]. In sum, none of Longman's (1933) characters can be 312 considered to be either autapomorphic or differentially diagnostic for Austrosaurus because 313 all are more widely distributed within Sauropoda. However, these characters do suggest that 314…”

“…The rearticulation of the vertebral column, successfully undertaken by SFP and JPN, 335 revealed that the three specimens described by Longman (1933) were found to articulate with 336 one another, with the undescribed condyle-cotyle pairs forming a sequence succeeding those 337 three (Appendix 1). The preserved presacral series, as articulated, comprises the 338 posteriormost cervical vertebra, and dorsal vertebrae I-V (Appendix 1; Fig.…”

Austrosaurus mckillopi Longman, 1933 was the first Cretaceous sauropod reported from Australia, and the first Cretaceous dinosaur reported from Queensland (northeast Australia). This sauropod taxon was established on the basis of several fragmentary presacral vertebrae (QM F2316) derived from the uppermost Lower Cretaceous (upper Albian) Allaru Mudstone, at a locality situated 77 km west-northwest of Richmond, Queensland. Prior to its rediscovery in 2014, the type site was considered lost after failed attempts to relocate it in the 1970s. Excavations at the site in 2014 and 2015 led to the recovery of several partial dorsal ribs and fragments of presacral vertebrae, all of which clearly pertained to a single sauropod dinosaur. The discovery of new material belonging toof the type individual of Austrosaurus mckillopi, in tandem with a reassessment of the type seriesmaterial collected in the 1930s, has facilitated the rearticulation of the specimen. The resultant vertebral series comprises six presacral vertebrae—the posteriormost cervical and five anteriormost dorsals—in association with five left dorsal ribs and one right one. The fragmentary nature of the type specimen has historically hindered assessments of the phylogenetic affinities of Austrosaurus, as has the fact that these evaluations were often based on a subset of the type material. The reappraisal of the type series of Austrosaurus presented herein, on the basis of both external morphology and internal morphology visualised through CT data, validates it as a diagnostic titanosauriform taxon (, tentatively placed in Somphospondyli),, and characterised by the possession of an accessory lateral pneumatic foramen on dorsal vertebra I (a feature which appears to be autapomorphic) and by the presence of a robust ventral midline ridge on the centra of dorsal vertebrae I and II. The interpretation of the anteriormost preserved vertebra in Austrosaurus as a posterior cervical has also prompted the re-evaluation of an isolated, partial, posterior cervical vertebra (QM F6142, the “Hughenden sauropod”) derived from the upper Albian Toolebuc Formation (which underlies the Allaru Mudstone). Although this vertebra preserves an apparent unique character of its own (a spinopostzygapophyseal lamina fossa), it is not able to be referred unequivocally to Austrosaurus and is retained as Titanosauriformes indet. Austrosaurus mckillopi is one of the oldest known sauropods from the Australian Cretaceous based on skeletal remains, and potentially provides phylogenetic and/or palaeobiogeographic context for later taxa such as Wintonotitan wattsi, Diamantinasaurus matildae and Savannasaurus elliottorum

“…), se trata del anquilosaurio mejor conocido en el hemisferio sur. El espécimen más completo parece estar momificado y conserva restos del contenido estomacal (cololito descrito por Molnar y Clifford, 2000). El cráneo carece de la mayoría de las ornamentaciones dérmicas típicas de otros anquilosaurios, por lo que se observan las suturas entre los huesos craneales (Molnar, 1996).…”
