We all know about the Tyrannosaurus Rex and Triceratops, but what about the Gigantosaurus, pictured above, or the Amargasaurus? These are just a couple of the little-known dinosaurs highlighted at a new exhibit at the Royal Ontario Museum, Toronto, Canada.
“Ultimate Dinosaurs: Giants from Gondwana” looks at recently discovered dinosaur species from South America, Africa and Madagascar, some of which have never before been displayed in Canada. Not content with simply assembling the skeletons and putting them on a pedestal, the curators have painted the walls with richly detailed murals and have also created Augmented Reality experiences where visitors can interact with the displays to learn more. You can even flesh out a dinosaur skeleton to see how paleontologists recreate these fearsome beasts from the bones they find.
The exhibit looks at how continental drift affected the dinosaur evolution during the Mesozoic Era 250–65 million years ago. At the start of this period there was one giant land mass called Pangaea. This later divided into Laurasia in the north and Gondwana in the south, which in turn separated into the continents we’re familiar with. This increasing isolation led to dinosaur species evolving separately.
Some of these unusual dinosaurs will surprise you. The long-necked Futalognkosaurus was one of the biggest animals to have ever walked the earth, measuring 110 feet long and weighing as much as 10 elephants. Suchomimus had a face like a crocodile and the Majungasaurus appears to have been a cannibal. Majungasaurus bite marks have been found on the bones of other Majungasaurs.
“Ultimate Dinosaurs: Giants from Gondwana” runs until March 17, 2013.
You’ve heard us sing the praises of the Appalachian Trail on more than one occasion here on Gadling. It’s the 2181-mile long trekking route that runs from Georgia to Maine that is considered amongst the best in the world. Turns out, the trail just got a whole lot longer, stretching all the way across the ocean to Ireland.
Officially, the AT is an American trail, and more than 2.5 million hikers use at least some segment of it on an annual basis. But there is also an International Appalachian Trail that extends all the way to the most northerly point of Newfoundland, Canada, adding an additional 1900+ miles to the route. That IAT is now jumping across the pond to Ireland, where it will run from Donegal to Antrim. According to Paul Wylezol, Chairman of the International Appalachian Trail, Ireland was added to the IAT because of “its direct physical connection to Newfoundland across geologic time, and its cultural and ethnic connection to eastern Canada and the US in modern times.”
In other words, Ireland once was connected to North America as part of the super-continent known as Pangaea, and because of that, it is getting added to the Appalachian Trail. Organizers hope to also add sections in Scotland, Norway and Greenland, as mountains in those locations are geologically related to the Appalachian Mountains. In fact, there are some indications that they may have once been a single range, before continental drift pushed the Earth’s land masses out to their current locations.
Hiking the length of the Appalachian Trail has long been considered one of the most impressive accomplishments in long distance trekking. For those hoping to achieve that feat in the future, it has suddenly gotten a lot longer and more challenging. I don’t think a pair of water proof boots are going to cut it.
