Cretaceous Ecosystem: Dinosaurs and Early Birds Coexisting by a River #1435437 (License: Personal Use)

This scientifically informed paleoart illustration depicts a diverse Cretaceous ecosystem where large sauropods graze in the background, agile theropods like *Sinornithosaurus* and *Yutyrannus* hunt near the water’s edge, and early avian species-including enantiornitheans and basal ornithuromorphs-wade or take flight. The setting features a shallow river flanked by conifers, ferns, and fallen logs, with atmospheric mist suggesting a humid, temperate climate. Fossil evidence from sites like Liaoning and Yixian informs the plumage, posture, and ecological interactions shown.

Used on educational science websites, museum exhibits, or paleontology blogs to illustrate Mesozoic biodiversity, evolutionary transitions (especially dinosaur-bird links), and ecosystem dynamics; targets users seeking accurate, visually engaging reconstructions for learning or research.
