Within the late Eighties, paleontologist Nikolai Spassov stumbled upon fossilized animal enamel within the Nationwide Museum of Pure Historical past in Bulgaria. The fossil had a handwritten word with an indecipherable scribble. It took years for Spassov to grasp the place the fossil got here from, and what the word stated. 

“I noticed that I used to be holding in my palms the stays of a brand new species of fossil panda,” Spassov advised Mashable.

This animal, Agriarctos nikolovi, was a detailed relative of the large panda that lives in Southwest China at present, although not a direct ancestor. It is exceptional {that a} similarly-sized panda as soon as roamed present-day Europe and researchers are simply studying concerning the species.

“The brand new species from Bulgaria is geologically the newest and probably the most developed European species of panda,” Spassov emphasised. This discovery supplies concepts concerning the doable evolutionary paths of pandas and the way their inhabitants dispersed over time, he added. 

“I noticed that I used to be holding in my palms the stays of a brand new species of fossil panda.”

Spassov collaborated together with his colleague Qigao Jiangzuo from China, and their findings had been printed within the Journal of Vertebrate Paleontology. They named the newly found species Agriarctos nikolovi in honor of the curator Ivan Nikolov who initially collected the fossilized enamel.

They ate greater than bamboo

The tooth fossils give clues concerning the historic panda’s whereabouts and its weight-reduction plan, Spassov defined.

Coal deposits on the stained fossils counsel the traditional panda lived in swampy and humid forested areas, locations the place decomposed vegetation finally (over hundreds of thousands of years) grew to become coal.

The traditional panda tooth fossils additionally counsel their feeding habits had been totally different from the long-lasting large panda we see at present in China. In the present day’s large panda weight-reduction plan consists nearly fully of bamboo. However the European panda Nikolov unearthed didn’t absolutely depend on bamboo, the research discovered. That is as a result of their enamel weren’t highly effective sufficient to always crush exhausting woody bamboo stems. The traditional pandas doubtless ate up softer vegetation, and so they had been largely vegetarians. 

Intense competitors led to vegetarianism

European pandas lived alongside carnivores, Spassov stated. They competed with massive predators like saber-toothed tigers, hyenas, and different bears that roamed through the Miocene interval (between 23 and 5 million years in the past). Amid all this competitors, species atop the meals chain attempt to keep away from competitors by discovering totally different diets. This wrestle for finite energy doubtless drove the panda lineage in direction of vegetarianism, Spassov defined. “The competitors was typically critical,” he stated.

These panda fossils are vital hole fillers. Which means, till now, scientists had a much less full image of the traditional bears which are intently associated to the surviving panda species in China, Juan Abella, a paleontologist at Miquel Crusafont Catalan Institute of Paleontology in Spain, advised Mashable. Abella was not a part of the brand new research.

Abella printed the same research in 2012 that described the oldest identified ancestor of the large panda clade that after wandered Spain, utilizing fossils dated round 11.6 million years in the past. The brand new species Spassov recognized is certainly rather more intently associated to the surviving large panda, he famous. 

“Hopefully, we will remedy all these evolutive paths that lead in direction of the extant panda,” Abella stated.
