rip to plateosaurids and pengornithids but things had to be cut

Right you asked for this the other day so here we go, All 29 dinosaurs discovered this year

Ornithopoda

-Meneffeeceratops, ceratopsian found in New Mexico USA -Sierraceratops, same as above, but a chasmosaur rather than a centrosaur -Sinocephale, new name for Chinese Stegoceras species -Spicomellus, ankylosaurian from Morocco, with spikes fused onto its ribs [Anthem's Funkiest Discovery Award] -Tlatolophus, Mexican parasaurolophin hadrosaur -Ornatops, New Mexican brachylophosaurin hadrosaur -Yamatosaurus, basal Japanese hadrosaur -Portellosaurus, Spanish hadrosauroid -Fylax, Spanish hadrosauromorph -Napaisaurus, Chinese iguanodontian

The fact that it's nearly the end of the year and i didn't hear about any of these before astounds me

Ty for telling me!

Crested hadrosaurs are lambeosaurines, not parasaurolophines.

Oh lord, did I write that? .....It was late, okay?

Abstract

The lambeosaurine Tsintaosaurus spinorhinus has traditionally been reconstructed with an elevated, hollow, spike-like crest composed entirely of the nasal bones, although this has been disputed. Here, we provide a new reconstruction of the skull of this species based on reexamination and reinterpretation of the morphology and articular relationships of the type and Paratype skulls and a fragmentary crest. We confirm the presence of a supracranial crest composed of the elevated nasal bones, but also including the premaxillae. We hypothesize that the crest is a tall, lobate, hollow structure that projects dorsally and slightly caudally a distance greater than the height of the skull along the quadrate. In our reconstruction, the nasal passage passes through the crest, but enters the skull rostral to the tubular process of the nasals, not through it. Tsintaosaurus spinorhinus is rediagnosed on the basis of a suite of cranial autapomorphies including a circumnarial fossa subdivided into three accessory fossae, prefrontal with ascending rostral process and lateral flange, nasals fused sagittally to form elongate tubular process that rises dorsally from skull roof, each nasal being expanded rostrocaudally into a rhomboid distal process, and medial processes of premaxillae at the summit of the cranial crest inserted between rhomboid processes of nasals. Tsintaosaurus spinorhinus lacks characters that are present in more derived lambeosaurines (parasaurolophins and lambeosaurins), such as rotation of the caudal margin of the crest to an acute angle with the skull roof, lateral processes of the nasals that enclose part of the intracranial cavity and participate in the formation of the walls of the common median chamber, and a smooth narial fossa lacking ridges and accessory fossae. We hypothesize that ancestrally the rostrum of lambeosaurines may have been more similar to that in Saurolophinae, and became subsequently reduced in complexity during evolution of the group.
