Archaeorhynchus spathula

†Archaeorhynchus spathula was an early ornithuromorph bird of the Early Cretaceous, discovered in the Yixian Formation of Liaoning, China. A small carnivorous bird with a spatula-shaped bill adapted for filter-feeding or probing soft substrates, it lacked the long bony tail of Archaeopteryx but retained other primitive features. Described in 2007, it expands our understanding of Early Cretaceous bird diversity.

Diet & Feeding

Carnivore

Archaeorhynchus spathula was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Early Mesozoic Era

Archaeorhynchus spathula lived during the Cretaceous Early period of the Mesozoic Era, approximately 145.0 to 100.5 million years ago.

The Cretaceous saw continued dinosaur evolution with the rise of ornithopods and early ceratopsians. Flowering plants first appeared and began to transform terrestrial ecosystems. Spinosaurus and other large theropods lived during this time.
