Spheroolithidae

† Spheroolithidae is a family of fossil dinosaur eggs (ootaxa) from the Late Cretaceous of Argentina, characterized by spherical eggs with a distinctive eggshell microstructure. These eggs are tentatively attributed to titanosaur sauropods.

Diet & Feeding

Herbivore

Spheroolithidae 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

Spheroolithidae 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.
