This is Haolong dongi, a new species of iguanodontian ornithopod found covered in what is basically,,, hedgehog quills??

The fossil is a stunningly preserved skeleton from China that includes evidence of hard armour scales on the tail (like in the much smaller Kulindadromeus), and a coat of spines along its neck and back! The name appropriately means "spiky dragon".

Not only is a spiny iguanodont wild on its own (this individual is over 2 metres long and is a juvenile, other ornithopods with quill-like structures are much smaller), these spines also appear to be an entirely new skin structure? They're apparently not feathers or scales, but a secret third thing.

Thank you for existing. I’m gonna miss you.
