The fragmentary skeleton of a single hadrosaurid person was uncovered at the Taipinggang website of the Dalangshan Formation near Zhaoqing city, Guangdong province, China.

The specimen is in between 70 and 67 million years of ages (Maastrichtian age), and consists of vertebrae, a humerus, ilium, thigh and tibia.

“The specimen was gathered from the Sanshui Basin in the northwestern part of the Pearl River Delta in South China, which is the closest inland basin to the South China Sea in the South China Land Source,” stated China University of Geosciences paleontologist Donghao Wang and associates.

“A big location of Upper Cretaceous layers divided into 2 big depositional zones, takes place within it.”

“The stratigraphy is well comprehended, however couple of vertebrate fossils have actually been discovered, conserve for the previously mentioned tyrannosauroid teeth from the Taipinggang website.”

“The brand-new lambeosaurine was discovered in red gravel in the 2nd member of the Dalangshan Formation.”

The person belonged to the people Lambeosaurini, which is otherwise improperly represented in the Chinese fossil record.

“The fossil record of Hadrosauroidea happens throughout the upper Lower and Upper Cretaceous layers internationally,” the paleontologists stated.

“Hadrosauroids include graded basal members and the obtained Hadrosauridae, the latter of which includes the Lambeosaurinae and Hadrosaurinae or Saurolophinae.”

“The most distinguishing character joining lambeosaurine hadrosaurids is the hollow supracranial crest, formed by the paired premaxillae and nasals, that might have operated in acoustic and/or visual signaling.”

“The fossil record of the Lambeosaurinae extends from the Santonian to the Maastrichtian.”

“So far, 4 types have actually been discovered in China: Charonosaurus jiayinensis Jaxartosaurus sp., Tsintaosaurus spinorhinusand Sahaliyania elunchunorum“

According to the scientists, the brand-new specimen is the very first lambeosaurine understood from South China.

“It represents the very first hadrosauroid from the Sanshui Basin and the very first lambeosaurine from South China,” they stated.

“This specimen recommends the capacity for future fossil discoveries in the Cretaceous deposits in the Sanshui Basin and shows that this location was as soon as home to a normal Late Cretaceous Laurasian dinosaur animals.”

The group’s paper was released in the journal Historic Biology
