September 2016 Newsletter

Autumn is my favorite season of the year! School is here and the holiday season is approaching! The stores are already into Halloween and Thanksgiving…wish they would finish one holiday before starting another one! Take some time to relax and come visit DRC and see what is happening in Woodland Park.
Largest of its kind ever found
The track, which measures 1.3 yards across, probably belonged to the Abelisaurus, a biped dinosaur that once roamed South America, said Argentine paleontologist Sebastian Apesteguia, who is studying the find. This was a meat eating predator which lived about 80 million years ago. The print was found about 40 miles outside the city of Sucre in central Bolivia by a tourist guide. The soft clay area is well known for dinosaur tracks. Skeletal remains of the Abelisaurus have also been found in this region.
Skull likely bridges gap in horned dinosaur evolution
A new species of dinosaur recently discovered is simply known as Hannah, for now. It is in the Ceratopsian family and it potentially bridges the
evolutionary gap between the Centrosaurus and the Styracosaurus. Hannah would not be much different from either of these two previously discovered species, except that its horns show a combination of characteristics from both. Evolution would have continued to change the horns of dinosaurs over time, and that’s what is probably being seen here with Hannah. The Centrosaurus has been found in deeper layers of earth, while the Styracosaurus has been found in higher strata. Hannah was found in between the two, which shows it likely bridges an evolutionary gap between the two species. Hannah’s skull was discovered in 2015, and in June of 2016 the team returned to see what remained of the skeleton to still be unearthed. As of now the skeleton is nearly complete and they will finish the dig next summer. Hannah was found horn first, the tip peeking out of the dirt in Alberta’s Badlands. Scott Persons who originally found Hannah was allowed to nickname the dinosaur after his beloved dog who sometimes helps on digs with him.
Dinosaur found in South Africa
The dinosaur Heterodontosaurus tucki is believed to have roamed the earth about 200 million years ago during the Early Jurassic. Found in 2005, this is the most complete skeleton ever found of
this species. The Evolutionary Studies Institute at the University of the Witwatersrand (Wits) in Johannesburg took the skeleton to the European Synchrotron Radiation Facility (ESRF) in Grenoble, France to be scanned in July of 2016.

Heterodontosaurus was a small, plant eating animal with grinding teeth in the back of the jaw and big canines in the front. Billy de Klerk found the fossil in a stream bed on a farm near Grahamstown, in the Eastern Cape. Enough rock was removed from the bones to identify the animal, but the skeleton was too small and delicate, and the rocks around it too hard to enable scientists to fully study the anatomy. The fossil was therefore sent to the ESRF to be X-rayed which will allow scientists to reconstruct it in incredible detail.
