Scientists and designers unveiled connected Thursday (April 2, 2026) a handbag made with collagen derived from Tyrannosaurus rex fossils from the U.S. successful a unsocial instauration intended to show the worth of laboratory-grown leather.
The teal-coloured container volition beryllium displayed connected a stone successful a cage nether a replica of a T. rex astatine Amsterdam’s Art Zoo depository until May 11 aft which it volition beryllium auctioned, with a reported starting terms of more than fractional a cardinal dollars. Scientists down the inaugural said the material was developed utilizing past macromolecule fragments extracted from dinosaur remains that were inserted into an unidentified animal’s compartment to nutrient collagen that was turned into leather.
“There were a batch of method challenges,” said Thomas Mitchell, CEO of The Organoid Company, 1 of three companies down the alleged “T. rex leather” bag. Genomic engineering steadfast Organoid and originative bureau VML, different of the firms down the project, antecedently collaborated connected creating a elephantine meatball successful 2023 by combining the DNA of a woolly mammoth with sheep cells. Che Connon, CEO of Lab-Grown Leather Ltd. that worked connected producing the leather for the handbag from the engineered collagen, said the T. Rex root gave it other “oomph”.
“It’s not conscionable astir a greenish alternate to leather, it’s a technological upgrade,” Connon said of lab-grown leather.
Scepticism
Some scientists extracurricular the task person expressed scepticism astir the word “T. rex leather”, saying worldly from different animals would beryllium needed.
Dutch vertebrate paleontologist Melanie During, of the Vrije Universiteit Amsterdam, said collagen tin persist successful dinosaur bones lone arsenic fragmented traces that cannot beryllium utilized to recreate T. rex tegument oregon leather.
Thomas R. Holtz Jr., a paleontologist astatine the University of Maryland, likewise said immoderate collagen identified in T. rex fossils comes from wrong bone, not skin, and that adjacent perfectly matching proteins would deficiency the larger-scale fibre enactment that gives carnal leather its distinctive properties.
“I would accidental that erstwhile you bash thing caller for the archetypal time, determination is ever criticism,” Mitchell said successful response.
“And I deliberation we’re really grateful for that criticism. It’s the bedrock of technological exploration ... I deliberation this is the closest anyone has gotten and will astir apt ever get to make thing that’s T. rex.”
