Scientists Say $600,000 Lab-Grown "T-Rex Leather" Handbag Is Actually Something Laughable

A Polish fashion brand released a handbag claimed to be made from lab-grown T-rex leather, priced at nearly $600,000 for an auction in Paris. Scientific experts questioned whether the underlying material truly originates from Tyrannosaurus rex. The claim relies on a 2005 discovery of soft tissue associated with 68-million-year-old T-rex bones, which some researchers argue may be bacterial growth rather than genuine dinosaur flesh. The bag’s “leather” was reportedly produced using protein data from that tissue sample, including chicken protein fused with a supposed T-rex protein sequence. A fossilized protein expert said the result is synthetic collagen generated by an AI model trained largely on chicken species, meaning it is not truly dinosaur material.

"The authenticity of the sample has major implications for the Enfin Levé bag, the designers of which used data from the tissue sample to produce the "leather." Further complicating things is the presence of chicken protein - which was fused with the T -Rex's supposed protein sequence to create the leather material for the $600,000 bag. As postdoctoral researcher and fossilized protein expert at the University of Turin told DW, that means the resulting material doesn't really qualify as dinosaur."

"According to German publication DW News, the debate stems from the definition of "T-rex leather." Back in 2005, paleontologists uncovered what they believed to be soft tissue connected to the 68-million-year-old bones of a T - rex in Montana - a biological discovery previously believed to be impossible. That bit of tissue has caused a ton of fuss, with some researchers arguing the tissue was really a clump of bacteria colonizing the fossil instead of genuine dinosaur flesh, DW explained."

""What they have done is create synthetic collagen using an AI model trained on a variety of different species, mainly chickens," Dekker explained. "A very interesting development in itself, but it is not a dinosaur. In fact, it's more chicken than anything else." Even if the bag isn't made of genuine Tyrannosaurus hide, though, the whole situation offers a fascinating glimpse at the state of lab-grown leather, which"
