May 28th

On this day in dinosaurs, we present another double feature.

2010 – Diabloceratops published

Around 79 million years ago in present-day Utah, a member of the ceratopsian family sported an impressive set of horns on its frilled head. Like the other members of this imposing group, this animal had a signature arrangement of horns: a small horn on the nose, a horn above each of its eyes, and two long spikes protruding from the top of its neck frill. Because of this configuration, scientists dubbed the animal Diabloceratops.

At the time it was discovered, Diabloceratops was the oldest known ceratopsid and was linked with earlier proceratopsid forms by having an accessory opening in its skull that disappeared in later (and more publicly recognized) horned dinosaurs.

2004 – Maryland Science Center opens Dinosaur Mysteries

Also on this day, the Maryland Science Center opened a real hands-on exhibit for those little aspiring paleontologists. Dinosaur Mysteries features more than a dozen dinosaur skeletons and opportunities to interact with many displays–giving kids the chance to experience the dinosaur world kinesthetically.

There are plenty of inducements for adults as well–Tyrannosaurus rex mounted with gastralia (uncommon), full size models of dinosaurs including Maryland’s own Astrodon, and dynamic skeletal mounts that provide excellent photo opps.
