Bistahieversor Gigantic Trackers
Bistahieversor, the Bisti Beast, stomped into the second wave of Gigantic Trackers in Jurassic World Dino Trackers alongside Elasmosaurus. It was the first time this New Mexico tyrannosaur had ever been made as a toy by Mattel. The figure is a big, sandy coloured hunter with a dark jaw, a row of tall black spines down its back, a chomping bite and a side-to-side tracking swing, and it comes with a strap-on tracker harness. Here is what it looks like, what it does, and how to unlock it in the Jurassic World Play App.

Name Decoder: What Does Bistahieversor Sealeyi Mean?
It is one of the hardest dinosaur names on any Jurassic World box, so here it is broken into its three parts.
Put together it means Sealey’s destroyer from the place of the adobe formations. Most fans just call it the Bisti Beast. Try saying it as bis-TAH-hee-eh-VER-sor.
What Is Gigantic Trackers?
Gigantic Trackers was the largest regular assortment in Mattel’s Dino Trackers line. Each figure is roughly 35 cm long, has a species-specific attack plus a side-to-side tracking motion, and comes with removable tracking gear, a nod to the tracking devices seen in Jurassic World Dominion. Wave 1 paired Sinotyrannus with a Stegosaurus, and wave 2 brought Bistahieversor and Elasmosaurus.
The Gigantic Trackers name carried on in Epic Evolution and Chaos Theory, and Primal Ambush keeps the big figure slot alive with its Gigantic Thrashers.
Paint and Colours
The figure is mostly a pale sandy cream, a fitting desert colour for an animal named after New Mexico badlands. Dark navy covers the lower jaw, the arms and a set of bold stripes around the neck, and a rust brown speckled patch runs down the back between the shoulders and hips. From the hips back the tail darkens to black, matching the tall spines along the spine. Yellow-green eyes and a red mouth finish the face.
Sculpt and Detail
Head and jaws
The skull is deep and boxy with a row of bumps over the snout and heavy ridges above the eyes. The jaw drops wide to show a red mouth and two rows of cream teeth, and the dark lower jaw makes the open bite look extra dramatic. A deep snout is exactly what scientists highlight in the real Bistahieversor, so this is the most accurate part of the sculpt.
Body, spines and harness
The body has fine pebbly scales, thick muscular legs and small clawed arms. Its most eye-catching feature is a crest of tall black spines running from the shoulders well down the tail. The removable tracker harness is a black strap with cables and a small device that wraps around the neck and shoulders.

Action Features and Articulation
✓ Opening jaw✓ Posable arms✓ Legs forward and back★ Press the shoulders: chomping bite★ Press the back: side-to-side swing✓ Removable tracker harness✗ No sound or lights
Press down behind the head and the neck dips forward as the jaw snaps open for a chomping bite. Press on the middle of the back and the body swings from side to side, the tracking motion every Gigantic Trackers figure shares, as if the animal is scanning for prey. Both moves are purely mechanical, so there are no batteries to replace and nothing to wear out but the plastic.
Size and Specs
Product code HLP27, sold in the HLP23 Gigantic Trackers case, for ages 4 and up. It is the same length as the Sinotyrannus from wave 1, so the two tyrannosaur relatives make a natural pair on a shelf.
Is It Worth Buying?
Bistahieversor is a great pick for tyrannosaur fans who already have a T. rex and want something different. It was the first toy of this animal in the Jurassic World range, the two attack moves are easy for younger kids, and the sandy, striped look stands out among the many green and brown predators. The made-up back spines are the only thing purists will grumble about.
It is mostly found second hand now. Check that the tracker harness is included when you buy one used.

About Bistahieversor
Bistahieversor sealeyi was named in 2010 by Thomas Carr and Thomas Williamson. Bones of this tyrannosaur had been collected in northwestern New Mexico for decades and filed under other names, until a closer study showed they belonged to a new animal. It is known from a nearly complete adult skull and partial skeleton plus a juvenile, from the Kirtland and Fruitland formations, about 75 million years old.
It reached roughly 8 to 9 m long. Its deep snout matters to scientists: it is the most primitive tyrannosaur known with the tall, deep face that later reached its peak in Tyrannosaurus rex. The skull also has an unusual extra opening above each eye and a keel along the lower jaw.
While Albertosaurus and Daspletosaurus ruled further north, Bistahieversor was the top predator of the southern part of western North America, and its adult skull is on show at the New Mexico Museum of Natural History and Science in Albuquerque.
