Frontier Ceratopsians

For most of the time that we've known about them, large ceratopsians seemed to be limited to North America. Smaller species were more widespread, inhabiting both North America and Asia, but were scarce elswhere. Overall the past five years, however, ceratopsian fossils have come in new shapes as well as from new places:

1. Ajkaceratops - 2010 - Hungary, 86-84 million B.C.E

2. Turanoceratops - 1989 - Uzbekistan, 90 million B.C.E.

3. Sinoceratops - 2010 - China, 72-66 million B.C.E.

4. Pachyrhinosaurus (perotorum) - 2012 - Alaska, 70-69 million B.C.E. (northmost ceratopsian and latest Pachyrhinosaurus species)

5. Koreaceratops - 2011 - South Korea, 103 million B.C.E.

6. Coahuilaceratops - 2010 - Mexico, 72.5-71 million B.C.E. (southmost large ceratopsian) 

The range ceratopsians inhabited may have gone even further: Two possible ceratopsians called Notoceratops and Serendipaceratops were identified from fragmentary bones in Argentina and Australia, respectively.
