1923
 
Walter Granger and W.K. Gregory describe and name the first Protoceratops species: Protoceratops andrewsi.
 
1971
 
A fossil is found with a Protoceratops locked in apparent combat with a Velociraptor - the two are believed to have died simultaneously, perhaps in a sandstorm.
 
1975
 
Teresa Maryanska and Halszka Osmólska describe a second Protoceratops species, Protoceratops kozlowskii. Most scientists now consider this invalid - their specimen is thought to be of an example of a different animal, Bagaceratops.
 
2001
 
A second valid species of Protoceratops is described and named: Protoceratops hellenikorhinus.
 
2011
 
A Protoceratops specimen that was uncovered in 1965 is found to be preserved with its own footprint - the first known example of a dinosaur fossil preserved with its own footprint.
 
2011
 
A fossilized nest with 15 young Protoceratops andrewsi is found. It is the first Protoceratops nest to be found, and suggests that Protoceratops may have cared for their young.
