Prismatoolithus ilekensis

† Prismatoolithus ilekensis was a fossil egg ichnotaxon (Dinosauria) from Russia. These Early Cretaceous fossil eggs are attributed to dinosaurian or avian parents and provide evidence of nesting behavior and reproductive strategies in ancient ecosystems.

Diet & Feeding

Herbivore

Prismatoolithus ilekensis 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 Early Mesozoic Era

Prismatoolithus ilekensis 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.
