Volkswacht Bodensee - First leather bag made from T-Rex cells fails to sell at Paris auction

Auctioneers Giquello had touted the "one-of-a-kind" piece to sell for more than $500,000 but bids barely broke the $150,000 mark, said the Drouot house where the sale took place.

Unveiled in the spring in Amsterdam, the bag was created from traces of collagen from the femur of a T‑Rex found in the US state of Montana 25 years ago.

"In recent years, we've developed techniques -- biotechnologies that allow us to instruct a cell culture to produce, so to speak, genuine T‑Rex skin in the laboratory," Iacopo Briano, a palaeontology expert associated with the sale, recently told AFP.

He noted the material differs from vegan leather, which is mostly made from plastic.

"In this case, it's derived from a cell culture, so it's 100 percent skin. And at the same time, it comes from an animal that went extinct 67 million years ago!" he said.

With no precedent to go on, Alexandre Giquello, whose auction house is organising the sale, explained they had to "come up with a price" that would reflect both the amount of investment required to create the bag and its rarity.

Giquello estimated the value at between 300,000 and 500,000 euros ($346,000 to $576,000).
