Bactrosaurus is a kind of medium-sized herbivorous dinosaur belonging to the Hadrosauroidea group that lived in modern-day China during the late Cretaceous period.

The name Bactrosaurus means “lizard with a club-shaped head.” It derives from the Greek words bactron (“club”, “stick”, “rod”) and sauros (“reptile”, “lizard”). This refers to the vertebrae’s tall, hefty, club-shaped spinous protrusions. It is also important to note that this name is frequently rendered wrongly as “the lizard of Bactria.”



Bagaceratops is a small-horned dinosaur (Ceratops) that is closely related to Protoceratops. Bagaceratops lived in the Gobi Desert, Mongolia, and China during the late Cretaceous period. Bagaceratops was described in 1975 based on fossils found by Teresa Maryaska and Halszka Osmólska during the Polish-Mongolian Paleontological Expeditions.
