We calculated water vapor conductance (a product of eggshell porosity) from the first definitively identified sauropod egg (Megaloolithus patagonicus) from the Auca Mahuevo locality in Argentina. We...
Juvenile Birds from the Early Cretaceous of China: Implications for Enantiornithine Ontogeny (2007)
LUIS M. CHIAPPE, JI SHU'AN, JI QIANG
Mesozoic remains of embryonic and early juvenile birds are rare. To date, a handful of in ovo embryos and early juveniles of enantiornithines from the Early Cretaceous of China and Spain and the Late...
A NEW PHORUSRHACID (AVES: CARIAMAE) FROM THE MIDDLE MIOCENE OF PATAGONIA, ARGENTINA (2007)
SARA BERTELLI, LUIS M. CHIAPPE, CLAUDIA TAMBUSSI
The anatomy of a new, enormous phorusrhacid (Aves: Cariamae) from the Middle Miocene Collón Curá Formation of northwestern Patagonia (Río Negro province, Argentina) is described. The new...

Abnormal, multilayered eggshells are frequently reported in fossil specimens. However, previous reports of this pathological condition pertain to taxonomically unidentified fossil eggs or eggshell...
Nest Structure for Sauropods: Sedimentary Criteria for Recognition of Dinosaur Nesting Traces (2004)
LUIS M. CHIAPPE, JAMES G. SCHMITT, FRANKIE D. JACKSON, ALBERTO GARRIDO, LOWELL DINGUS, GERALD GRELLET-TINNER
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...

Henry Gee and Luis Rey have provided an entertaining and creative account of the life and times of dinosaurs.
LATE CRETACEOUS AVIAN EGGS WITH EMBRYOS FROM ARGENTINA (2002)
MARY H. SCHWEITZER, FRANKIE D. JACKSON, LUIS M. CHIAPPE, JAMES G. SCHMITT, JORGE O. CALVO, DAVID E. RUBILAR
LUIS M. CHIAPPE, MARK NORELL, JAMES CLARK
We describe an exquisitely preserved new skull of a bird from the Late Cretaceous sandstones of Ukhaa Tolgod, southern Mongolia. Derived similarities shared between this skull and the holotype of...
An Embryonic Oviraptorid (Dinosauria: Theropoda) from the Upper Cretaceous of Mongolia (2001)
MARK A. NORELL, JAMES M. CLARK, LUIS M. CHIAPPE
An embryonic oviraptorid skeleton is described within an egg from the Late Cretaceous Djadokha Formation of Ukhaa Tolgod, Mongolia. The specimen comprises the ventral part of the skull and most of...
A New Carinate Bird from the Late Cretaceous of Patagonia (Argentina) (2001)
JULIA A. CLARKE, LUIS M. CHIAPPE
A new bird from the Late Cretaceous of Patagonia (Argentina), known from associated wing elements, is described and its phylogenetic position evaluated. Fossil taxa as well as representatives of...
