Q What does the “U-turn hypothesis” propose about how Sinoceratops came to live in Asia?
- A Ceratopsians evolved in Asia and then migrated to North America
- B Ceratopsians evolved in North America and later migrated back to Asia through Beringia
- C Ceratopsians migrated from South America to Asia through Africa
B Ceratopsians evolved in North America and later migrated back to Asia through Beringia
Recent studies have suggested that ceratopsians may have evolved and increased in size in North America before migrating back to Asia via Beringia, which was connected by a land bridge at the time.
Sinoceratops is an important dinosaur for understanding this migration between continents.
