Benchmarks: May 12, 1905: Andrew Carnegie donates 'Dippy the Dino'

As one of the world’s wealthiest philanthropists, Andrew Carnegie had come to expect that people would praise and honor him, but May 12, 1905, would be an unusual day for the Pittsburgh steel magnate. Never before had he been honored for donating a dinosaur. Carnegie’s contribution of a massive plaster model of a Diplodocus — at the time the largest-known animal to have ever trod the planet — to London’s Natural History Museum was part of the Scotsman’s dream to rid the world of war, which he called “the foulest blot upon our civilization.”

Getting there and getting around Denver

Denver International Airport is the best arrival point for exploring Denver and the surrounding area. A car is necessary to see many of the attractions described here. If you fly in, you can rent a vehicle at the airport or take the new light rail into town and rent a car as needed. Although all of these sites are open year-round, snow sometimes obscures the tracks during winter and early spring, and trails can be muddy. May through October is an ideal time to visit the region.

Volcanic aerosols not enough to cause mass extinctions?

Mass extinctions — when more than half of Earth’s species disappear in a geologic instant — offer some of the planet’s most perplexing unsolved mysteries. Prolonged periods of volcanic activity have long been prime suspects for these ancient whodunits, the most recent of which finished off the last nonavian dinosaurs at the close of the Cretaceous about 66 million years ago. But scientists debate how drastic the environmental effects of such volcanism might have been, and whether other factors — like asteroid impacts, as in the end-Cretaceous extinction — played a big role as well.

A jaw all the wider to bite you with

Tyrannosaurus rex  is often depicted with its fearsome jaws wide open, but few studies have looked at how wide the Cretaceous predator’s gape could actually be.

Ancient eggshells may reveal dinosaur body temperatures

Whether dinosaurs had metabolisms more like slow, cold-blooded reptilians or fast, warm-blooded birds has long been a mystery. Fossilized bones, which don’t preserve the delicate cell membranes that facilitate heat production in warm-blooded animals, are not likely to answer the question. Fossilized eggshells, however, might be just the ticket to determining the past body temperatures of egg-laying females, which, scientists say, might help address whether the dinosaurs’ metabolisms were warm or cold.

Gouges in the ground are best evidence yet of dinosaur courtship

Dinosaurs may not have been lonely in love, according to new research published in Scientific Reports. An international team of scientists has discovered the first tangible evidence that dinosaurs engaged in courtship behaviors: parallel scrape marks up to about 1.8 meters long and 40 centimeters deep that were gouged in the ground during the Cretaceous.

Triceratops relative 'Wendi' sported a fantastic frill

The discovery of a 79-million-year-old frilled and horned relative of Triceratops is shedding light on the early evolution of the ceratopsid’s distinctive look. The new specimen, discovered in a quarry in southern Alberta, Canada, and described recently in PLOS ONE, was named Wendiceratops pinhornensis after the famed fossil hunter Wendy Sloboda of the University of Lethbridge in Alberta, who discovered the site in 2010.
