Researchers in central India uncovered a Late Cretaceous nesting site with 92 nests and 256 titanosaurs’ eggs, possibly used by multiple species; six egg types suggest diverse populations; no adult or hatchling bones found, indicating minimal parental care and incubation likely driven by sun and sediment; one ovum-in-ovo egg hints at bird-like reproductive traits.
CT scans of 11 Late Cretaceous titanosaur eggs from India’s Lameta Formation uncovered a second inner shell inside one egg — an ovum-in-ovo structure previously known only in birds. The dual shells and microstructure indicate sequential egg development within the oviduct, suggesting titanosaurs had segmented oviducts and avian-like reproductive biology, a rare insight since the other eggs showed normal, single-shell architecture.
Paleontologists in India discovered the first dinosaur egg containing another egg, a condition previously known only in birds, suggesting similarities in reproductive anatomy between titanosaurs, birds, and crocodiles, and providing new insights into dinosaur biology.
