He snorted. “My Latin’s nonexistent.”

“Butterflies are Lepidoptera—‘scaly wings.’ This is a lepidodendron—‘scaly tree’—a stalk from a giant tree fern. Ferns a hundred feet tall. Carboniferous period. That plant is three hundred million years old if it’s a day.”

Tyler grasped the exposed end of the fossil and gently tugged and twisted, extricating it in a succession of rasping clinks. He sighted along its length, studying the intricate geometry of the diamond-shaped pattern. “You sure this is a scaly stem? Not a scaly snake?”

“Those scales are leaf scars,” I said. “Also called leaf cushions. But they do look like reptile scales, for sure. Actually, circus sideshows used to exhibit these as fossilized snakes. You’re a born huckster, Tyler.” I stood up, scanning the ground ahead and catching a telltale flash of grayish white: weathered bone. “But enough with the paleo lesson. We’ve got work to do. Let’s start with pictures.” Tyler laid the fossil aside and opened the equipment bin.

A few years before — when I’d first started working with the police on murder cases — a detective at the Kansas Bureau of Investigation had taught me a crucial forensic lesson: You can never have too many crime-scene photos, because working a crime scene requires dismantling it; destroying it. The KBI agent’s approach to crime-scene photography sounded like something straight from Bonnie and Clyde’s bank-robbery playbook: “Shoot your way in, and shoot your way out”—start with wide shots, then get closer and closer, eventually reversing the process as you’re finishing up and leaving the scene. Tyler had been quick to master the technique, and even before we stepped across the tape at the strip mine, he had the camera up and the shutter clicking. It wasn’t unusual for Tyler or me — sometimes both of us — to come home with a hundred 35-millimeter slides from a death scene, ranging from curbside shots of a house to frame-filling close-ups of a .45-caliber exit wound.

As Tyler shot his way in, so did I, though I was shooting with my eyes and my brain rather than a camera. The pelvis: female, I could tell at a glance; subadult; probably adolescent. The size: small — five feet, plus or minus. As I zoomed in on the skull, I reached out to pluck a seedling that was growing beside it and obscuring my view. As I tugged, though, the skull shifted — bone grating against rock — and I froze. “I’ll be damned,” I said, for the second time in minutes. The seedling, I realized, wasn’t growing beside the skull; it was growing from the skull — from the left eye orbit, in fact — something I’d never seen before. Wriggling my fingers gently beneath the skull, I cradled it, then lifted and twisted, tugging tendrils of root from the rocky crevices below. The seedling was a foot tall, the fronds of tiny oval leaves reminding me of a fern. As I held it up, with Tyler snapping photographs and the sheriff and TBI agent looking on, I felt as if I were displaying a bizarrely potted houseplant. “Bubba,” I said, nodding toward the bin, “would you mind opening one of those evidence bags for me?” Meffert scrambled to comply, unfolding the paper bag and setting it on the most level patch of rubble he could find.

Leaning down, I set the skull inside the bag.

“You gonna just leave that tree in it?” asked Meffert.

“For now,” I said, bending the seedling so I could tuck it completely into the bag. “When we get back to UT, I’ll take it over to a botanist — a guy I know in the Forestry Department — and get him to slice it open, count the growth rings. However many rings he finds, we’ll know she’s been here at least that many years.”

“Huh,” Meffert grunted, nodding. Suddenly he added, “Watch it!”

Just as he spoke, I felt a sharp pain on my wrist. I looked down in time to see a wasp pumping the last of its venom into the narrow band of skin between the top of my glove and the bottom of my sleeve. “Damnation,” I muttered, flattening the wasp with a hard slap. “Where the hell did that come from?”

“Yonder comes another one,” Meffert said, “right out of the evidence bag.” Sure enough, at that moment a second wasp emerged from the open bag and made a beeline for my wrist, drawn by the “danger” pheromones the first one had given off. Meffert’s hand darted downward, and by the time I realized what he was doing, he had caught and crushed the wasp in midair, barehanded. “Sumbitches must be nesting in that skull,” he said. I was dubious, but not for long; two more wasps emerged from the bag, both of them deftly dispatched by Meffert. We watched and waited, but the attack seemed to be over.

“You’re quick, Bubba,” I said, rubbing my wrist. “You that fast on the draw with a gun?”

He smiled. “Nobody’s ever give me a reason to find out.”

“Well, watch my back, if you don’t mind.”

I resumed my inspection of the postcranial skeleton, scanning the bones from neck to feet. “Y’all were right about the size,” I said. “Just guessing, I’d say right around five feet. And female,” I added, bending low over the flare of the hip bones. “And young.”

“How young?” asked Cotterell.

I hedged. “Be easier to tell once we get the bones back to the lab and finish cleaning ’em up. But I’m guessing teenager.”

“Any chance this is just some old Indian skeleton?” the sheriff asked hopefully. “Make our job a hell of a lot easier if she was.”

“Sorry, Sheriff,” I said. “She’s definitely modern.”

Meffert chuckled. “Isn’t that what you said about that dead guy over near Nashville a couple years ago? The one turned out to be a Civil War soldier?”

“Well, she’s lying on top of all this shale,” I pointed out. “If she’s not modern, this must be the world’s oldest strip mine.” I said it with a smile, but the smile was forced, and it was contradicted by the deep crimson my face had turned at the reminder of the Civil War soldier.

“Don’t take it so hard, Doc,” Meffert added. “You only missed it by a hunnerd-something years.”

“Too bad that soldier didn’t have a tree growing outta his head,” the sheriff added. “Big ol’ pecan tree, with a historical marker on it? You’da got it right for sure.”

Meffert grinned. So did I, my teeth clenched behind drawn lips.

We rode in silence down the winding mountain blacktop toward Wartburg. Tyler was absorbed in the fossil he’d brought back, his fingers tracing the intricate diamond patterning as if he were blind, examining it by touch alone.

For my part, I was brooding about the parting shots by the TBI agent and the sheriff. They’d been joking, good-naturedly, no doubt, but the conversation had stung, even worse than the wasp, and the sting took me back, in my mind, to the event they were dredging up. Just after my move to Knoxville, I’d been called to a rural county in Middle Tennessee, where a decomposing body had been found in a shallow grave behind a house. The remains were in fairly good shape, as rotting bodies go — pink tissue still clung to the bones — and I’d estimated that the man had died about a year before. In fact, we later learned, the dead man was Col. William Shy, a Civil War soldier killed in the Battle of Nashville in 1864.

In hindsight, there were logical reasons I’d missed the time-since-death mark so widely. Colonel Shy had been embalmed, and until modern-day grave robbers had looted the grave — looking for relics — the body had been sealed in an airtight cast-iron coffin, which had kept bugs and bacteria at bay. But those explanations sounded more like excuses than I liked. They also provided precious little comfort in court, I’d learned, again and again: Hostile defense attorneys in contemporary criminal cases took great delight in bringing up Colonel Shy, rubbing my nose in my blunder as a way of undermining my testimony against their clients.

Colonel Shy wasn’t the only case where I’d been derailed by difficulty in determining time since death. Another murder case — a case I’d consulted on shortly before my move to Knoxville — still haunted me. A suspect in the case had been seen with the victim two weeks before the body had been found — the last known sighting of the victim — and the investigator and prosecutor pressed me hard: Could I testify, with certainty, that the murder had occurred then? “No,” I’d been forced to admit, “not with any scientific confidence.” As a result, the suspect had gone free.

Hoping to fill the gaps in my knowledge — determined to avoid such frustrations and humiliations in the future — I had combed through stacks of scientific journals, seeking data on decomposition. But apart from a few musty articles about insect carcasses — dead bugs found in bodies exhumed from old cemeteries — I’d found virtually nothing. Nothing recent, at any rate, though I had come across a fascinating handbook written by a death investigator in China centuries before, in 1247 A.D. — a research gap of more than seven centuries. The good news was, I wasn’t the only forensic anthropologist who was flying by the seat of his pants when estimating time since death. The bad news was, every forensic anthropologist was flying by the seat of his pants.

The interesting news, I realized now, as Tyler and I reached the base of the mountain, and the road’s hairpin curves gave way to a long, flat straightaway, was that the field was wide open. Time since death — understanding the processes and the timing of postmortem decomposition — was fertile ground for research.
