On Taphonomy

Taphonomy is the study of what happens to bodies, especially bones, after death on their way to fossilization. Few remains make it that far, but when they do, taphonomy is the journey through which the biological becomes geological. In life, bones are tissues, despite their rigidity. Calcium flows in and out of the bone bank as […]

Beetles, Time Travelers

In the summer of 2011, the Smithsonian’s National Museum of Natural History was in the process of doing some bug relocation. Specifically, they were moving some of their beetles from the museum building downtown out to a storage facility in the suburbs—specifically, the non-plant-eating scarabs. It was a lot of scarabs. The museum has a […]

Holding the Last of Winter

You’ve noticed the cold starting to leave. The light has been strengthening, sun lifting every day, and the wind has lost some of its bitterness. Twenty-three and a half degrees of tilt to the planet, you can feel every degree. Two mornings ago a blizzard hit where I live in Colorado. It was a fierce […]

When America was Great, the First Time

We were great in the Ice Age. Big weapons, big animals, big land. While parts of the world were crawling with hominids for a million years or more, this side of the planet was off limits. Getting here was never easy, not in the late Pleistocene, not now. The Americas are bookended by the world’s two […]

Letters from the Dead

A recent email from a stranger posed a query as to what to do with Native American artifacts in her possession. I’ve never found the answer to be an easy one. The woman didn’t take much. She called it, “a small box of artifacts, a few really nice perfect arrows and a couple that where truly made […]

How to Read Ancient Mayan

In this month’s issue of National Geographic, I tell a story of an ancient dynasty of Maya kings who made perhaps the region’s best attempt at creating what we might call an empire. It’s a twisting tale of political maneuvering and ambition unlike any other in the Pre-Columbian world. It’s actually kind of incredible that […]

Redux: On My Way to Burning Man

In the summer of 2014 I backpacked across the Black Rock Desert to Burning Man with a small group of friends, after which this piece was originally published. It has been only slightly altered. Since the lake bed is from late Pleistocene origin, and the loud and luminous eruption of this annual event will be […]

Going Paleo in Florida

The Florida panhandle got some big press this week, yet another early human find confirmed in North America, people entrenched along the Aucilla River south of Tallahassee 14,550 years ago. This came from an underwater excavation where archaeologists have been plumbing a sinkhole through which the river flows. Artifacts and megafauna remains have gathered in the […]
