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.”

Turtle finds lower Altiplano elevation estimate

Rare turtle fossils uncovered in Bolivia suggest that, about 13 million years ago, the southern portion of South America’s Altiplano — the arid, high-elevation plateau immediately west of the Andes — was far lower than previously thought.

Fossil leaves provide clues to ancient Australian habitat

Researchers have long thought that the scrublands of Australia developed over the last 25 million to 30 million years as part of a global trend toward colder and drier climates in which rainforests yielded ground to more open, fire-prone environments.

China's Red Deer Cave people may have survived until the last ice age

In the 1980s, a collection of bones from very small hominids was excavated from a cave in southwestern China, alongside a number of bones from a species of large red deer. Nicknamed the “Red Deer Cave people,” but not yet declared a distinct species, researchers previously dated radiocarbon in the sediments where the bones were found to about 14,000 years ago. In a new comparative study, the same team has now found that the hominids from which the bones came appear to have been similar to — although far smaller than — Homo habilis and Homo erectus, suggesting it could indeed be a new species.

Bat signals

Bats, the only true-flight mammals, first appeared during the Early Eocene after a period of acute global warming known as the Paleocene-Eocene Thermal Maximum. Despite decades of study, however, much remains unknown about bats. Recent discoveries are shedding new light on the natural history of these creatures, which today comprise one of the most diverse mammalian groups.

Inside an icthyosaur's brain

While the dinosaurs were busy ruling the continents in the Mesozoic, an order of marine reptiles known as the ichthyosaurs ruled the oceans. Ichthyosaurs are well known from numerous fossils, but they are often found flattened, limiting researchers’ ability to study the skulls and braincases as they existed in life.

Parasites of the Paleozoic

Parasitism — an ecological relationship in which one species benefits at the expense of its host — is common among living organisms, but as most parasites are soft-bodied, it’s rare to find them preserved in the fossil record. Two recent discoveries, however, have lengthened the short list of ancient parasites

Mammoths may have suffered from bone disease

The demise of mammoths, which went extinct by the end of the Pleistocene about 12,000 years ago, is thought to have been brought about by a combination of climate change and overhunting by early humans. A new study indicates that another culprit might have contributed as well: Mammoth bones retrieved from Northern Eurasia — from sedimentary strata close to the animals’ last known appearance in the fossil record — appear to show evidence for bone diseases associated with nutrient deficiencies.
