Dendroolithidae

†Dendroolithidae is an extinct family of dinosaur eggs defined by a dendrospherulitic shell microstructure — a branching crystalline pattern unique among ootaxa. Known from Late Cretaceous deposits of Asia, these eggs are attributed to sauropod dinosaurs. Dendroolithid eggs provide key data on sauropod reproductive biology and nesting behavior.

Diet & Feeding

Herbivore

Dendroolithidae was a plant-eating dinosaur. Herbivores typically fed on ferns, cycads, conifers, and other vegetation available during their era. Many herbivorous dinosaurs developed specialized teeth and digestive systems for processing tough plant material.

Time Period

Cretaceous Late Mesozoic Era

Dendroolithidae lived during the Cretaceous Late period of the Mesozoic Era, approximately 100.5 to 66.0 million years ago.

The final age of dinosaurs, featuring iconic species like Tyrannosaurus rex, Triceratops, and Velociraptor. Dinosaurs reached their peak diversity before the catastrophic asteroid impact at the Chicxulub crater ended the Mesozoic Era.
