And it turns out the horns probably had a purpose - one that rodents would likely benefit from today. Samantha Hopkins’ 2005 paper on Ceratogaulus with figures featured in this episode (Thanks, Samantha!): https://royalsocietypublishing.org/doi/10.1098/rspb.2005.3171#d3e609 Thanks to Ceri Thomas (https://nixillustration.com), Lucas Lima (https://252mya.com/gallery/lucas-lima), R.
