What’s this then? Haolongood has revealed images of a species that wasn’t shown on their big teaser poster earlier this year: Triceratops!
It appears that these two are based on “Yoshi’s Trike,” MOR 3027, which has the longest horns of any Triceratops specimen in proportion to its size (although it wasn’t fully mature when it died, so it may have grown into them more had it lived).
