The Smallest Frills

The smallest dinosaur with frills on its head was found in 1997 in Montana and was dated from 108 to 104 million years ago. The remains were not described until 2014 but by that time a new set of remains had been unearthed. This set of remains constitutes the holotype and is housed at the Sam Noble Museum in Norman, Oklahoma. This holotype material consists of the mandible and skull of a juvenile dinosaur. Weighing in at approximately 1.5 kg Aquilops americanus  is the lightest and smallest of the ceratopsian family. It will make a great topic of conversation for the week to be sure.
