"What interests me about this paper is that they only show one bone and I'd like to see more," said Blackwell. She'd also like to look the cut marks with more powerful instruments to measure their depth and compare them to other samples.
Blackwell is not convinced humans were eating hyenas, however.
"They could have been processing them for their beautiful pelts," she told Discovery News.processing Over all, evidence of humans eating carnivores is scarce, agreed Rodríguez-Hidalgo.
"During the Palaeolithic carnivore consumption by hominids is as uncommon as today," Rodríguez-Hidalgo said.
In the later part of the Palaeolithic there are a few cases of humans processing the carcasses of foxes, bobcats and badgers. They were probably using their fur, but perhaps eating the meat as well. There are also signs from Maltravieso and elsewhere in southern Europe that hominids processed lynx, fox, badgers and lions.
"Among the large carnivores, bears are sometimes killed," Rodríguez-Hidalgo said. "However, the hyena never appears as a game prey."
