My Storify about the U@live session itself has been published here.

The diplodocid sauropod specimen nicknamed 'Apollo' on display at the Pennsylvania Armory

After the Raffles Museum of Biodiversity Research was able to raise funds for a new building through public donations, the decision was made to solicit further donations so as to cover the expense of acquiring and exhibiting the dinosaur fossil specimens known as Twinky, Apollo, and Prince. This met with resistance and criticism from people who failed to realise the intangible ability of dinosaurs to awe, inspire and educate. Some questioned the relevance of spending so much on North American dinosaurs when the museum should be focusing on local and regional biodiversity.  Nevertheless, the museum was successful in its bid. 

On the same day of the session, we had received news that Twinky, one of three diplodocid sauropod dinosaur skeletons destined for our upcoming natural history museum, had finally arrived in Singapore. (I'll probably talk more about diplodocid dinosaurs another time)

There weren't any sauropods at the U@live session, but to help stimulate the audience's interest and curiosity, there were 2 sets of dinosaur fossils on stage, and we were invited to take photos and even (gently) touch them.

Edmontosaurus (also known in the past by names such as Trachodon, Anatosaurus, Anatotitan, and many others) is one of the largest and most famous of the hadrosaurs (aka "duck-billed" dinosaurs), and is represented by numerous fossil specimens discovered in the Late Cretaceous of the United States of America and Canada.
