LEGO Dinosaurs: Tyrannosaurus Rex Skeleton Model Unveiled After 68 Million Years

The LEGO Dinosaur Fossils: Tyrannosaurus Rex set, available exclusively at the LEGO Store, is a visually stunning and ambitious build. You're immediately struck by its impressive size; this is a 1:12 scale model of a real T-Rex. As you examine it more closely, the intricate details become apparent: the ribs are constructed at varying lengths to form a realistic rib "cage," while the use of dark-colored bricks creates shadow effects, accentuating the light-colored "bone" bricks. Despite its complex appearance, the set is surprisingly easy to assemble, which only adds to its allure.

Growing up, I was fascinated by dinosaurs, especially the towering T-Rex skeleton at the American Museum of Natural History. This fascination was further fueled by Ray Bradbury's "A Sound of Thunder," a sci-fi short story that vividly captures the awe of encountering such a colossal creature:

"It came on great oiled, resilient, striding legs. It towered thirty feet above half of the trees, a great evil god, folding its delicate watchmaker's claws close to its oily reptilian chest. Each lower leg was a piston, a thousand pounds of white bone, sunk in thick ropes of muscle, sheathed over in a gleam of pebbled skin like the mail of a terrible warrior."

For many years, the T-Rex was popularly depicted standing upright with its tail dragging on the ground, as shown in this image:

However, scientific understanding has evolved, revealing that the T-Rex actually stood with its spine parallel to the ground, using its tail as a counterbalance. This is exemplified by "Sue," the most complete T-Rex skeleton ever discovered, which is 90% intact:

Sue's discovery included gastralia, small bones that supported the T-Rex's belly and breathing, initially omitted from public displays due to their unknown placement. This finding led to a revised understanding of the T-Rex's physique, which was leaner in earlier depictions, like in the 1993 film Jurassic Park:

Today, we recognize the T-Rex as a heavier, more robust creature, weighing between nine to ten tons, as seen in this updated model based on Sue's bones:

This new understanding is reflected in the LEGO Dinosaur Fossils: Tyrannosaurus Rex set, which adopts a more horizontal posture in line with current scientific consensus. Although it does not include the gastralia, the model's rib positioning suggests a "barrel-chested" structure, contrasting with the lean, efficient killer often portrayed in popular media. The set's arms are also positioned forward, consistent with the updated "Sue" display at the Field Museum in Chicago.

The set comes in 25 sealed plastic bags. You start by assembling the black stand, followed by the T-Rex's backbone, which attaches to vertical supports. The rest of the model, including the neck, legs, hips, ribs, arms, tail, and head, is built sequentially and attached to the spine and stand. The legs and torso are fixed, but the arms, head, and tail are adjustable and posable.

Stretching nearly three-and-a-half feet from tip to tail, this model demands a significant amount of space. It's best displayed on a wide, flat surface like a dresser or coffee table, where it can truly dominate the area it occupies.

The set is part of the LEGO Jurassic Park franchise, which explains the inclusion of two minifigures—Alan Grant and Ellie Sattler—from the original film, along with a Jurassic Park-branded placard. However, the connection to the franchise feels somewhat forced. The set's name, 'Dinosaur Fossils: Tyrannosaurus Rex,' does not directly reference the movie, and the instructions even provide an option to remove the minifigure and placard display, allowing the skeleton to stand alone.

This inclusion feels unnecessary because the T-Rex set, with its size, scope, and price, sells itself. Much like the LEGO Titanic build, it stands as a piece of art in its own right, transcending the need for movie memorabilia tie-ins.

LEGO Dinosaur Fossils: Tyrannosaurus Rex, Set #10335, retails for $269.99 and comprises 3011 pieces. It is available exclusively at the LEGO Store.
