Egg cases typically contain one embryo, except for big skate and mottled skate egg cases, which contain up to 7 ...
Early Jurassic estuarine ecosystem, with Palaeoxyris egg cases attached via tendril to Neocalamites, with hybodonts in the background.

Oothecae are made up of structural proteins and tanning agents that cause the protein to harden around the eggs, providing protection and stability. [1] The production of ootheca convergently evolved across numerous insect species due to a selection for protection from parasites and other forms of predation, as the complex structure of the shell casing provides an evolutionary reproductive ...
