Porosity and water vapor conductance of two Troodon formosus eggs: an assessment of incubation strategy in a maniraptoran dinosaur.

This article offers information on a study which explored variation in porosity and water vapor conductance across two eggs of Troodon formosus, a small theropod dinosaur from the North American Upper Cretaceous. The sample specimens involved in the study are two complete Troodon formosus eggs each from partial clutches, Museum of the Rockies 750 and 299. The article also describes the method for estimating egg size, clamping the eggshell and calculating porosity as well as the results of the study.
