A new Lego-built dinosaur has been unveiled for adult fans of Jurassic Park and this one is the most anatomically correct so far – even without its skin on. Everyone loves dinosaurs, so it’s no surprise that they’ve been a big part of Lego since forever,

On Tuesday, Lego revealed its latest “Dinosaur Fossil” set, a series of Jurassic Park and Jurassic World sets featuring dino skeletons and skulls. The new fossil set is a massive Tyrannosaurus rex made up of 3,145 pieces.

The set centers on a three-foot long T-Rex skeleton replica based on the one seen in the original Jurassic Park film. It also comes with mini-figures of Dr. Alan Grant and Dr. Ellie Sattler, as well as an information plaque with interesting facts about the Cretaceous-era lizard king.
