From the Field: Finding “Miss Piggy” and Late Ordovician fossil fragments

Away to the airport this morning to see Ed off to Winnipeg - there goes our ace bear protection and GPS expert! At least we had a chance to do the firearms familiarization before his departure, so all are up to speed on handling various pyrotechnic deterrents. I’ll ride shotgun in Ed’s absence, with Matt as backup, and incoming member Sean adds another pair of sharp eyes to the fossil team.

Summerasaurus Part VI: Un-jacketing dino bones in the Vertebrate Palaeontology Lab

Today, we thought we’d offer you a behind-the-scenes look at the Vertebrate Palaeontology Lab to see what happens to dino bones between being excavated and being put on display or used for research.

Clear skies at last! Down to the coast to catch good morning lighting and a fortuitously low tide, so we can see in detail how fossil-bearing Upper Ordovician carbonate deposits (445 million years old) at our main locality “lap” against the elevated flanks of a much more ancient rock mass. This highly resistant Proterozoic (about 2500 million-year-old) quartzite body is the remnant of a small island that formed part of an archipelago in shallow Ordovician subtropical seas.

Summerasaurus Part V: The Badlands

Posted: September 2, 2011 - 09:10 , by admin

Walking through the badlands is like walking through a western novel: canyons cut through the prairie, exposing layers of brown, gold, black and white sediment. Clichés keep popping up: tumbleweeds roll by, cactus pop out from unexpected places, and cattle skulls bleach in the sun. Scorpions hide in coal seams, soaking up the sun’s heat from the black rock that camouflages them. It’s a bit overwhelming at first, but once you accept the fact that you’re in a place unlike anywhere else in Canada, it all becomes simple and beautiful.

Summerasaurus Part IV: How to Find Dinosaurs

Posted: August 23, 2011 - 12:25 , by admin

Mark Farmer recently returned from an expedition to the badlands of southern Alberta with Dr. David Evans, Associate Curator of Vertebrate Paleontology at the ROM, in search of dinosaurs. Join us as Mark and Dr. Evans put up their notes from the field, detailing discoveries, how dinosaurs are found and excavated, life in the field and more.
