Micro-Trike!

Although they are frequently gigantic, people often forget that all dinosaurs, being egg-layers, started life pretty small. A reminder of this is in the latest Journal of Vertebrate Paleontology, where Goodwin et al. (2006) have published on the smallest Triceratops skull known to date. The adults’ skulls could be six feet long, among the largest of any land animals’ skulls, but this specimen is one mere foot long.

Interestingly, the young trike had already developed horns, perhaps indicating that the structures had uses other than sexual display.

If you can view TIFF files, there’s is a high-resolution image of the skull freely available here.

(By the way—should they be called pups, or chicks … or ceratoplets?)
