73 Million Years After the Flood: Unearthing the Ancient Mystery of Pachyrhinosaurus lakustai
Pachyrhinosaurus lakustai was first discovered in 1972 by a science teacher from Grande Prairie, Alberta named Al Lakusta. In what would prove a significant discovery, Lakusta located the dinosaurs in a rich bed of prehistoric bones at Pipestone Creek, Alberta. The bonebed is perched on the steep wall of a valley carved through bedrock, exposing strata of the Wapiti Formation.
When the area was finally excavated in 1986, paleontologists from the Royal Tyrrell Museum of Palaeontology in Drumheller, Alberta, were amazed to find an enormous wealth of bones. Some areas of the site averaged 100 bones per square meter.
The Pachyrhinosaurus lakustai herd that these researchers ultimately uncovered is a species of ceratopsid (or horned dinosaur) from North America's Late Cretaceous period. These formidable beasts were up to 8 metres (26 feet) long and weighed up to four tons. The most distinctive feature of this amazing beast is its massive head, which is dominated by large bony structures called 'bosses' above the nose and eyes (Pachyrhinosaurus means 'thick-nosed lizard') and a hefty frill of bone on the back of its skull festooned with small horns.
While their substantial armour of facial and cranial bone suggests a menacing nature, Pachyrhinosaurus lakustai was actually a herbivore that survived on tough, fibrous plants.
