A Mongolian ankylosaurid specimen identified as Tarchia gigantea is an articulated skeleton including dorsal ribs, the sacrum, a nearly complete caudal series, and in situ osteoderms. The tail is the longest complete tail of any known ankylosaurid. Remarkably, the specimen is also the first...

Analyzing taphonomic deformation of ankylosaur skulls using retrodeformation and finite element analysis
Download2012
Taphonomic deformation can make the interpretation of vertebrate fossil morphology difficult. The effects of taphonomic deformation are investigated in two ankylosaurid dinosaur taxa, Euoplocephalus tutus (to investigate effects on our understanding of intraspecific variation) and Minotaurasaurus...

A new microvertebrate site (≈72 Ma) in the Horseshoe Canyon Formation, south-central Alberta, is a deflational lag in interbedded silty shales. The site represents deposition on a waterlogged coastal plain ≈100 km to the west of the Bearpaw Sea. Approximately two-thirds (n=224) of the 388...

Structure of the manus and pes has long been a source of confusion in ankylosaurs, owing to the imperfect preservation or complete lack of these parts of the skeletons in most specimens, and the fact that many species appear to have undergone a reduction in numbers of digits and phalanges. New...
