Sinosauropteryx
Three specimens have been assigned to "Sinosauropteryx prima": the holotype GMV 2123 (and its counter slab [opposite face], NIGP 127586), NIGP 127587, and D 2141. Another specimen, IVPP V14202, was assigned to the genus but not to the only species by Zhang and colleagues. The assignment of an additional larger specimen to "S. prima", GMV 2124, was later found to be in error. All of the fossils were found in the Jianshangou or Dawangzhangzi Beds of the Yixian Formation in the Beipiao and Lingyuan regions of Liaoning, China. These fossil beds have been dated to 124.6–122 million years ago, during the early Aptian stage of the Early Cretaceous.
Jiangshanosaurus
Jiangshanosaurus was a titanosaurian sauropod that lived approximately 105 million years ago, during the Albian stage of the Early Cretaceous. Its remains were discovered in the Jinhua Formation of Lixian Village, Jiangshan county, in the eastern Chinese province of Zhejiang. The type and only known species, "Jiangshanosaurus lixianensis", was formally described by Tang Feng and others in 2001. Known material of "J. lixianensis" includes elements of the shoulder, back, pelvis, femur and tail. Although "Jiangshanosaurus" initially defied precise placement within Titanosaura, a recent paper considers it to be outside Lithostrotia.
