Holotype specimen (CRILAR-Pv 151) of Huayracursor jaguensis, a long-necked dinosaur that lived approximately 230 million years ago, placed in approximate anatomical articulation.

Rigorous skeletal of Pedopenna daohugouensis. Only the foot is shown as its taxonomic affinity is heavily debated due to the fragmentary nature of the holotype. The view is of its left foot in lateral view. The large boxes are 50mm and the small boxes are 25mm.

An overview of the known fossil material of Tyrannomimus fukuiensis. Fossil specimens shown in are not in the same scale. The bar is scaled for the paratype (FPDM-V-10295). The holotype (FPDM-V-11333) and paratype in are colored in red and blue, respectively. The right femur in is mirrored from the left one (FPDM-V-11338).
