Description

    HADROSAURID VERTEBRA
    Maiasaura peeblesorum
    Cretaceous, Campanian Stage
    Two Medicine formation, Bynum, Montana

    This is a caudal vertebra from the dinosaur known as the "good mother". The name was coined from the animal's egg nests, arranged in colonies and incubated by heat from rotting vegetation laid on top by the mother; fossils of hatchlings suggest they were unable to walk immediately, yet wear to their teeth indicates that the mother animals brought food to the still nest-bound young. This characteristic vertebra has fine bone quality and patina, with no restoration and an unusual curve to the long spiny process which may indicate an injury while the creature was alive. Presented on a metal display base, it stands 13 7/8 inches high.
