Dendroolithus furcatus

†Dendroolithus furcatus is a dendroolithid dinosaur egg oöspecies from Late Cretaceous China, distinguished by its forked (furcate) branching crystallite pattern in the eggshell. These large, round eggs were likely laid by titanosaur sauropods. Their occurrence in multi-layered nesting horizons suggests repeated use of nesting grounds over geological time.

Time Period

Cretaceous Late Mesozoic Era

Dendroolithus furcatus 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.
