Tim Brassey, 59, held a homemade sign with an image that had been altered to appear as if Trump was kissing Nigel Farage, the leader of the newly formed Brexit Party who spearheaded the campaign for Britain to leave the European Union.

“Trump and Brexit are basically the same thing,” Brassey said.

Some bacula are partly composed of cartilage, the same material that forms the human earlobe, which also doesn’t fossilise easily, “so just because a fossil mammal is missing a baculum” says Brassey, “it does not mean we can assume the animal was a female.”

“My project is part of a growing body of research to focus on the evolution and biomechanics of mammal genitalia”, explained Dr Charlotte Brassey from Manchester Metropolitan University.

I met Brassey after her fascinating lecture at a palaeontological conference last year.
