Palaeontologists are "pissed off" that the dinosaurs in the upcoming Jurassic Park film will not have feathers.
Evidence has been piling up since the first Jurassic Park film came out in 1993 that many dinosaurs were in fact feathered, New Scientist reports.
However the director of the fourth installment of the films, Colin Trevorrow last month tweeted: "No feathers. #JP4".
While dinosaurs have long been depicted as leathery-skinned lizards, evidence points to many dinosaurs, including velociraptors and some tyrannosaurs, having feathers adorning their bodies.
Palaeontologist and film consultant Mark Witton said he would be disappointed if filmmakers had decided against putting feathers on the dinosaurs.
