More than a decade ago, a 110-million-year-old dinosaur fossil was taken from its resting place in the Araripe Basin in Brazil under murky circumstances. Eventually, it landed in the State Museum of Natural History Karlsruhe (SMNK) in Germany—without legitimate export permits or clear documentation of its acquisition. Now, the specimen will go back to Brazil, German authorities announced today.

“We have a clear stance. … If there are objects in the collections of our museums that were acquired under legally or ethically unacceptable conditions, we will return them,” Theresia Bauer, who leads the Ministry of Science, Research and Arts for the German state of Baden-Württemberg, said in a statement to

Science

. Her ministry manages SMNK.

The decision “is admirable,” says Felipe Pinheiro, a paleontologist at the Federal University of Pampa, São Gabriel, who with others had pushed for the return of the fossil on

social media

. “As a Brazilian researcher, [I] am immensely happy that [the specimen] is going home.”

The ministry’s decision is an “emblematic” victory against colonialism in science, says Aline Ghilardi, a paleontologist at the Federal University of Rio Grande do Norte. “We have taken another step towards a real 21st century science … which is getting rid—even if slowly—of colonialist ties and biases,” she adds.

The official announcement closes a contentious chapter in the fossil’s history. In 2020, researchers at SMNK published a paper (with no Brazilian authors) in

Cretaceous Research

describing the dinosaur as a new species they named

Ubirajara

jubatus

.

The report attracted attention because the small dinosaur sported filaments apparently resembling mammalian fur, as well as

flamboyant spikes

erupting from its shoulders. But the researchers came under fire when Brazilian paleontologists alleged the fossil had been exported illegally. The journal

withdrew the paper

permanently in September 2021.


A


1942 Brazilian law

says collecting fossils in the country requires permits from the National Mining Agency and

that


all fossils found belong to the country

. A 1990 decree adds that


Brazil’s Ministry of Science, Technology and Innovation must approve

the export of all fossils

—an approval SMNK researchers failed to obtain—and that foreign researchers must collaborate with a Brazilian institution


to study them.

A


Science

story

noting conflicting accounts about the fossil’s export prompted the Baden-Württemberg science ministry to launch an internal investigation, according to a ministry spokesperson. The

Cretaceous Research

paper says the fossil was “brought to Germany along with scientific samples in 1995” by SMNK paleontologist Eberhard Frey. But in 2021, SMNK researchers said the fossil was imported in 2006 by a private company, then acquired by SMNK in 2009, the ministry told

Science

.  SMNK eventually admitted to the ministry it had “made erroneous statements.” The museum was unable to provide documentation on the acquisition of the fossil, or to prove it was imported before a German cultural protection law took effect in 2007, according to the m

inistry’s probe

.

Bauer called the conflicting accounts “scientific misconduct,” according to the German

newspaper

BNN


, but neither the ministry nor SMNK have disclosed any disciplinary actions against the museum’s researchers. Frey retired earlier this year and told

Science

today that he was not allowed to comment.

However, he told

BNN

today that the controversy involved him alone, and not SMNK scientific Director Norbert Lenz, who was a co-author on the

Cretaceous Research

paper. Lenz is leaving the museum at his own request on 30 September, according to the ministry, but told

BNN

his leaving was unrelated to

Ubirajara

. He did not respond to

Science

’s request for comment.

Bauer said in her statement to

Science

that Baden-Württemberg is committed to returning cultural assets when appropriate. “It is important that with the return we send a clear signal about the correct handling of collection items, their provenance and scientific honesty.”

SMNK will now examine whether the circumstances surrounding the acquisition of any other objects in its collection are comparably unclear, according to the ministry statement. “I am glad,” Pinheiro says, adding that

SMNK holds more than 40 other fossils

from Brazil. “This means that a few dozen other invaluable specimens are likely to make company to

Ubirajara

and return home.”

The Baden-Württemberg Ministry has identified the National Museum in Rio de Janeiro as a possible future location for the fossil. However, some researchers say its ideal home is the Museu de Paleontologia Plácido Cidade Nuvens, located in Santana do Cariri and part of the

Araripe UNESCO Global Geopark

where the fossil is thought to have been found.

Allysson Pinheiro, director of that museum, says he and other researchers have been in talks for almost a year with representatives of German public museums, including SMNK, about repatriating other Brazilian fossils currently in Germany.

Ghilardi hopes such repatriations will open doors for fairer collaborations between foreign researchers and institutions and their local counterparts. “European museums will not, and should not be emptied,” she says. “Fair exchanges and collaborations can be made, so that everyone can share in the benefits that fossils can offer.”
