#hadrosauroids

[noddytheornithopod]

just heard about Haolong and holy shit, a hadrosauroid iguanadontian with filamentous structures, similar to the ones in kulindadromeus (not the fuzz, the spinier looking filaments it also had)... feathers or similar to feathers in friggin hadrosauroids is wild to imagine

What actually is difference between hadrosauroids and hadrosaurids?

Hadrosauroids are all animals more closely related to Saurolophus than to Iguanodon 

Hadrosaurids are the group of the most recent common ancestor of Hadrosaurus, Saurolophus, Parasaurolophus, and all that ancestor’s descendants 

So Hadrosaurids are a more limited group than Hadrosauroids
