Subtiliolithus hyogoensis

† Subtiliolithus hyogoensis is an Early Cretaceous theropod egg ootaxon from Hyogo Prefecture, Japan, characterized by delicate thin-walled eggshell with finely distributed pores. This rare Asian theropod ootaxon adds to Cretaceous nesting records.

Diet & Feeding

Carnivore

Subtiliolithus hyogoensis was a meat-eating predator. Carnivorous dinosaurs were active hunters or scavengers, equipped with sharp teeth and claws for catching and consuming prey. They occupied the top of the food chain in their ecosystems.

Time Period

Cretaceous Early Mesozoic Era

Subtiliolithus hyogoensis 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.
