Nest Structure for Sauropods: Sedimentary Criteria for Recognition ...

"Six egg-filled depressions discovered in the Upper Cretaceous Anacleto 
Formation (Campanian) of Patagonia, Argentina, and interpreted as dinosaur 
nests, provide the only known evidence of titanosaurid sauropod nest 
construction. These nest trace fossils show truncation of sedimentary 
structures as well as differences in texture between the host substrate and 
in-filling sediment. Titanosaurid sauropods excavated and laid eggs in open 
nests rather than burying clutches in sediment. In addition, this paper 
establishes criteria for definitive recognition of excavated nests in the 
stratigraphic record."
