A smaller, earlier horned dinosaur that helps show the transition toward the larger, more elaborate ceratopsids. It did not yet have the full giant frill-and-horn look of Triceratops, but it sits close to that later line in the broader horned-dinosaur story. Lived from about 90 to 89 million years ago.
Zuniceratops
Lived from about 90 to 89 million years ago.
Triceratops ancestor
- Here's the key idea. Zuniceratops shows an earlier stage in the evolution of the horns and frill later made famous by Triceratops.
- Finally, the core takeaway. Zuniceratops is important because it shows that the classic ceratopsian head — larger frill and strong brow horns — evolved gradually. It helps bridge the gap between earlier, simpler horned dinosaurs and the later giant ceratopsids such as Triceratops.

When a source is corrected or expanded, it can be updated once at the tidbit level and reflected everywhere it appears.
Over time, this structure allows related ideas to reconnect naturally across disciplines and across years.
