I didn't get any dinosaur or anything similar named Heliceratops but there was Helioceratops and assuming that it was just a spelling mistake from spoiler provider
(I wouldn't necessarily call it a spoiler but a reference:)
Helioceratops: helio literally is sun so could be another sun reference & the name being sun-horned face (or: sun rises in the east and this dinosaur was found in East...so eastern horned faced dinosaur).
The only thing that bears actual straight forward story resemblance is that Sasaki's Triceratops is also a ceratops i.e. dinosaur with their horns being in faces and they are both herbivorous (don't know if that part is relevant at all)
