Thank you Caldey for sending us a photograph of your CollectA Deluxe Edmontosaurus feeding in the garden.  The dinosaur looks very much at home munching on some conifers.  Palaeontologists know from hadrosaur stomach contents that these Late Cretaceous herbivores did feed on conifers.  It is a delightfully composed photograph.  The viewing angle gives the impression

New Study Suggests Juvenile Maiasaura Ate Different Food to Adults
tooth feeding fossil juvenile Hadrosauria +2
A newly published scientific paper has provided fresh insights into the feeding habits of the famous hadrosaur Maiasaura peeblesorum. Analysis of tooth wear in juvenile Maiasaura compared to adult hadrosaurs suggests that young Maiasaura fed differently from fully grown animals. Researchers examined dental wear associated with Maiasaura peeblesorum fossil teeth.  Dietary insights may help to

 Today we're checking out a recently described hadrosaur with a unique look, Gongshuilong fanwei!Gongshuilong lived in what is now eastern China, during the late Cretaceous period, between 68 and 66 million years ago.  From beak to tail it measured about 23 feet (7m) long and would have been a plant-eater when alive.  The genus name translates from Mandarin to "Gong River Dragon" in reference to the Gong River near where its bones were discovered.Gongshuilong life reconstruction in watercolors b

Corythosaurus: Beast of the Week
crest Canada Canardia Corythosaurus Dinosauria +6
This week we will take a look at a well known duckbill dinosaur.  Enter Corythosaurus!  Corythosaurus was a plant eater that belonged to the lambiosaurine group within the family, Hadrosauridae. (duckbills)  Lambiosaurine hadrosaurs typically had hollow crests on their heads and narrower beaks compared to other kinds hadrosaurs.  It was closely related to other lambiosaurine hadrosaurs such as Parasaurolophus, Hypacrosaurus, Lambeosaurus, and Velafrons.  It lived in what is now Alberta, Canada,
