- "All I want for my services is the right to hunt one of the tyrannosaurs. A male, a buck only."
- —Roland Tembo(src)
The Tyrannosaur Buck is the male Tyrannosaurus rex seen in The Lost World: Jurassic Park as well as the original 1995 novel and is the individual that hunter Roland Tembo seeks to hunt during his trip to Isla Sorna while accompanying the InGen Harvest team. This T. rex later is tranquilized by Roland and is taken to San Diego where the animal escapes and rampages before he is able to be rounded back and brought back to Isla Sorna. He is the father of Junior.
Isla Sorna Incident (1997) and San Diego Incident
A few weeks after his son's birth, InGen Hunters Roland Tembo and Ajay Sidhu kidnapped his son wanting to use him as bait for the Tyrannosaur Buck. In response, he and the Doe travelled to the Hunters' encampment to rescue their son. They sensed the Juvenile T. rex inside the Fleetwood RV Mobile Lab and cornered the humans inside it. The Buck nudged the trailer to see if the object he was observing was alive.
Unknown to the Tyrannosaurus rex couple, the humans inside the trailer were not InGen Hunters, rather they were another group called the Gatherers who were fixing their son's leg after it had been broken by a drunk InGen CEO Peter Ludlow and wanted to return the juvenile to his family. Dr. Sarah Harding, one of the Gatherers, realized that the Tyrannosaurs were not exhibiting hunting behavior but was wanting to retrieve their infant. She and the other Gatherers handed the T. rex infant over to his parents after her realization. Afterward, the Tyrannosaur Buck and his mate hid their son in a safe place before returning to the Fleetwood RV Mobile Lab to destroy it.
They flipped over the rear half the vehicle, then smashed the front windshield and pushed the back half over the cliff, as the trailers were parked near the edge. Satisfied, the Rexes retreated, only to later return once again when Gatherer Eddie Carr came to rescue his teammates and friend, being notified by the sound of Eddie's Mercedes SUV. Upon finding the vehicle, the Buck tore the SUV apart before going after Eddie himself. The man attempted to use his air rifle, but it was too late; the Buck grabbed him by one end, and the Doe by the other, ripping Eddie in half. Satisfied, the Tyrannosaurus couple finally departed from the encampment.
Despite having rescued their son, the two Tyrannosaurs once again tracked the remaining InGen Hunters and Gatherers via the scent of their juvenile's blood that was stained on Sarah Harding's shirt. Upon reaching the campsite, the Buck poked his head inside her tent, sniffing the shirt hanging from a line stretched across the tent interior while Dr. Sarah Harding and Kelly Malcolm did their best to stay still. The noise woke up Carter, one of the Hunters, who alerted his fellow colleagues by screaming its presence. Lifting the tent from the ground and momentarily blinded, the Buck violently shook the tent from his face. The Tyrannosaur Doe then arrived on the scene and chased the hunters into a tight ravine while the Buck stayed behind to scavenge. While doing so, Roland took the chance to shoot the female Tyrannosaurus rex, who he mistook for the male, with his double-barreled rifle, only to find that Nick Van Owen had sabotaged his weapon. He then proceeded to shoot the Buck with an overdose of concentrated carfentanil in the hopes of killing him.
However, the male Tyrannosaur survived and was captured by the remaining InGen Hunters under the orders of Peter Ludlow to be transported to San Diego, California in North America where he hoped to display him, along with his infant, in the his new Jurassic Park being built there to replace the failed one on Isla Nublar.
Unfortunately, sometime during the trip, the tyrannosaur stopped breathing and entered a comatose state. In an effort to save the animal, he was administered an amphetamine to counter the large dosage of tranquilizer given to him when Roland shot him. The T. rex, now in a berserker state, broke out of his containment unit and attacked those serving on the ship. Somehow the Tyrannosaurus rex was lured into the cargo hold, where he stayed until Ludlow foolishly ordered the area checked once the ship docked at the InGen Docks at San Diego. Enraged, dehydrated and hungry, the Tyrannosaur stormed out of the cargo hold and smashed through the dock checkpoint before wandering into San Diego, causing chaos throughout the city. One of the first locations he first went through was a neighborhood. Finding a house with a backyard pool, the Buck effortlessly broke through the brick wall surrounding the yard and proceeded to slake his thirst by drinking the pool water. The family dog, un-phased by the intrusion, began to bark at the much larger predator only to be quickly silenced when the T. rex growled at him and devoured him seconds later. The noise awoke Ben, a child, who then dragged his (at first) disbelieving parents into his bedroom to show them the dinosaur; to their shock and horror. The boy took a picture, alerting the Tyrannosaurus, who simply growled angrily before returning to the city.
Rampaging through downtown, the Tyrannosaurus rex scared everyone he encountered. The tyrannosaur tested his surroundings in various ways including biting traffic lights and twisting them as well as smashing a bus with his head. Most of the citizens survived the havoc except for one unlucky individual. During his romp in the city, Doctors Sarah Harding and Ian Malcolm devised a plan to lure the raging animal back to the ship by using the infant to lure him (recalling how it followed it to the trailers before). After traveling to Jurassic Park: San Diego, they moved the infant to the InGen Docks in order to lead him to them. Peter Ludlow, however, had a different response; he ordered the police to kill the Buck so the chaos would end.
Upon hearing his son's cries, the Buck stopped his rampage and chased after Malcolm and Harding, following them all the way to the ship. Ludlow then entered the cargo hold, attracted by the growling of the infant, and attempted to capture him bare-handed. Unbeknownst to him, the Buck had followed him into the hold. Ludlow realized too late that he was trapped.
As the human attempted to scurry up the stairs and out of the hold, the Rex clamped down around his legs and dropped him back onto the floor. As Ludlow tried to stand up, the male Tyrannosaurus rex shoved him to the floor and encourages his son with gentle nudges to finish him off so he'll be able to hunt on his own when hes older, and proudly watches as his son pounces on the hapless executive and devours him alive. However, this victory was short lived as police helicopters surrounded the gaping cargo hold doors, their guns aimed to fire. It was only in the nick of time that Dr. Ian Malcolm was able to close the door to the hold, and Dr. Sarah Harding managed to tranquilize the Buck (who locked eyes with Malcolm briefly, almost as if in respect and gratitude). He and his infant were then shipped back to Isla Sorna where they were reunited with the Doe, the three apex predators reunited as a family.
The Tyrannosaur Buck's rampage in San Diego made InGen's cloned dinosaurs known to the general public. Dr. Ian Malcolm got his credibility back with the public now believing his account of the Isla Nublar Incident of 1993 after the Buck's involvement in the San Diego Incident. As a result of the San Diego Incident, the United States and the Costa Rican governments restricted Isla Sorna to humans. Despite these warnings, humans have step foot on the island after it was declared restricted. Most notable outside of poachers was the Dino-Soar, an illegal business that allowed people to paraglide around Isla Sorna's borders whose final operation lead to the Isla Sorna Incident of 2001.

Production and development
Dinosaur model supervisor Paul Giacoppo stated, "All of the computer models built for Jurassic Park were supposed to be female, but The Lost World also had to have males. So we modified the T-rex model to beef up the male. We got the Winston maquette of the male T-rex, which had a slightly different head structure, and we worked from that. Susan Ross and her painting team also did new paint jobs for the males, based on the Winston designs – the tiger-like raptor and the camouflage pattern that was on the male T-rex."
The T. rex animatronic in Jurassic Park III was actually the same animatronic for the Buck in The Lost World: Jurassic Park. Stan Winston Studios repainted the animatronic lighter colors, however, they can both still be recognized as the same robot by the facial scarring on the right side of the muzzle. During the production of the fight with the Spinosaurus, the animatronic's neck was broke clean off the robot, because the Spinosaurus animatronic was so big and powerful it destroyed the robot with one hit.
This left many of the crew stunned, shocked and even some mourning for the animatronic with John Rosengrant saying: “That was a really sad ending to a long night of shooting. The Spino threw one final blow and broke the T. rexs neck. The head collapsed, the neck tore open in the back, and hydraulic fluid shot out of it, almost like blood spurting.” Because of this mishap, this would eventually be the scene where the Spinosaurus towers over the T. rex after killing it.
- The face of the Buck is adorned with many facial scars and many of the teeth in his mouth are broken or missing. This is indicative towards the animal participating in fights for mating rights or dominance.
- It is unknown whether or not "Tyrannosaur Buck" is his official name. Fans refer to this male Tyrannosaur as this because Roland Tembo wanted to hunt a male T. rex that he referred to as a "Buck" and ended up capturing a male in the end.
- The male Tyrannosaurus along with the infant were the first dinosaurs to ever come to the mainland before the 2018 Dinosaur Outbreak.
- In-universe, the Buck was intended to weigh 8 tons (16,000 pounds) and reach a top running speed of 25 miles per hour.
