To all Paleonetters,

Many years ago, I heard somewhere that, despite egg-laying being well known in several clades of dinosaurs (e.g., ceratopsians), some dinosaurs were hypothesized to have given live birth.  I heard this applied to sauropods.  Sauropod embryos inside eggs have since been reported from South America.

What is the current status of the idea of live birth in some dinosaur groups?

Best,
