Megaloolithus is an oogenus representing fossil eggs assigned to titanosaurian sauropods from Late Cretaceous deposits in Western Europe. The eggs are generally spheroidal, with average diameters of approximately 30 centimeters, and are characterized by distinct eggshell microstructures used for taxonomic classification.

Observed variation in shell thickness and ultrastructure across specimens has generated hypotheses regarding their origin. Proposed explanations include taxonomic diversity among egg-laying titanosaurs or physiological stress related to calcium metabolism, potentially linked to environmental or dietary limitations. Megaloolithus eggs contribute significantly to understanding dinosaur reproductive biology, eggshell evolution, and nesting behaviors in Late Cretaceous ecosystems.
