For every lawyer asked by a 7-year-old, “What do you do at work?” this is what you wish you could answer: Fight over the fossils of two giant dinosaurs locked in mortal combat and entombed in sandstone 66 million years ago.

You might recall Lit Daily's previous coverage of the dispute between the current and former owners of a Montana ranch where the remains of the “dueling dinosaurs” —a 22-foot-long theropod and a 28-foot-long ceratopsian—were discovered, along with a complete T-Rex skeleton and a large Triceratops skull. The fossils are worth millions of dollars.

On Monday, the U.S. Court of Appeals for the Ninth Circuit ruling en banc punted the fight to the Montana Supreme Court.

“Because of the importance of the state law question, and the potential of different outcomes in federal and state courts, we have elected to certify the issue to the Montana Supreme Court,” wrote Chief Judge Sidney Thomas, joined by 10 colleagues on the bench—who have now collectively lost their claim to coolness among the pre-K and elementary school set.

The case presented an issue of first impression in Montana: Are dinosaur fossils minerals? It's a seemingly straightforward question with no clear answer—and implications that go beyond the immediate private contractual dispute.

As a group of paleontology associations and natural history museums represented by Covington & Burling's Gary Guzy and Pooja Kothari put it in an amicus brief, the decision could “destabilize title to countless important fossils in academic, museum, and private collections around the world.”

The fight began after Lige and Mary Ann Murray in 2005 bought a ranch in Garfield County, Montana from Jerry and Robert Severson. The Murray's purchase included the surface estate and one-third of the mineral estate. (Apparently in Montana, it's common to sever a property's mineral rights from its surface ownership.)

The Seversons expressly retained the remaining two-thirds of the ranch's mineral rights, which now belong to commercial extraction companies BEJ Minerals and RWTF, represented by Brian Lake and Shane Swindle of Perkins Coie. (The companies had been represented by Eric Miller at the firm until he was confirmed to the Ninth Circuit in February.)

All the parties agree no one was thinking about fossils when they made the deal, but a few months later, the Murrays started discovering the ancient remains of dinosaurs on the land.

In 2014, they sought a declaratory judgment that they were the sole owners of the fossils. The extraction companies filed a counterclaim asserting that the fossils are properly classified as minerals, which would mean they'd own two-thirds of them.

The Murrays, represented by Harlan Krogh and Eric Nord, Crist of Krogh & Nord, won before U.S. District Judge Susan Watters in Montana, but in November, a divided Ninth Circuit panel reversed Watters and held that fossils are indeed minerals.

“Although it could be argued that dinosaur fossils are unlike oil, gas, coal, and other substances traditionally thought of as minerals because they are not used as fuel, neither are many of the other substances specifically listed in the Webster's definition, such as salt, sand, and gravel,” wrote U.S. District Judge Eduardo C. Robreno of the Eastern District of Pennsylvania, sitting by designation. He was joined in the majority by Judge Milan D. Smith, Jr.

“In addition,” Robreno continued, “oil, gas, and coal all derive from the remains of plants and animals, just like dinosaur fossils, and should not be treated any differently because they are valuable for a different reason.”

The decision was greeted with dismay by leading paleontologists and museums.  First of all, they noted in their amicus brief, fossils aren't even minerals in the scientific sense. “Because fossils were initially formed through biological rather than geological processes, established scientific understanding holds that dinosaur fossils are not minerals,” the Covington team wrote.

“The panel also haphazardly applied a legal test designed to identify the subset of all minerals that a mineral deed would reserve,” they continued. “It focused only on whether these fossils are 'rare and exceptional' and possess 'special value,' concluding that the Montana Fossils are minerals because they meet these criteria. In fact, the mineral content of fossils has little value because it is common; the fossils' value derives from the biological information they convey about ancient life.”

The United Property Owners of Montana sounded the alarm as well. “[L]iterally untold tens of thousands of fossils have been transferred, sold and otherwise controlled and disposed of by owners of the fee title (surface estate), without regard to the separate and distinct interests of the owners of the mineral estate. This is well settled custom and practice across Montana, without a single outlier, until the panel's 2-1 decision,” wrote Colleen M. Dowdall of Dowdall Law in an amicus brief.

Dowdall argued that fossils fall under the law governing the taking of live wild animals, or ferae naturae.

Surface property owners in Montana “as a matter of law control who can access private land and take wild animals ferae naturae. It easily follows that the death of such creatures causes no change in the legal status of who controls their remains, no matter how old, nor what biological processes may occur in the interim.”

Ultimately, the Ninth Circuit may have felt it had little choice but to send the case back to Montana. On April 16, Montana Governor Steve Bullock signed into law a bill declaring that dinosaur “fossils are not minerals and that fossils belong to the surface estate”—which should shut down future disputes.

The Ninth Circuit did note that the new law does not affect proceedings in court before it took effect. Still, it would have been problematic if they reached an opposite conclusion from state lawmakers.

So alas, it's back to ERISA and immigration and prisoner appeals for the appellate judges—the dino case, at least for them, is extinct.
