The following weapons were used in the film The Lost world: Jurassic Park:

The Lost World: Jurassic Park (1997)

LAR Grizzly Big-Bore

Roland Tembo (Pete Postlethwaite) is seen in the film using an LAR Grizzly Big-Bore, made out to be a single shot tranquilizer gun. Sarah Harding (Julianne Moore) is later seen using the same tranquilizer rifle to shoot the T-rex while in San Diego. Some of the hunters are also seen using LAR Grizzlies, outfitted with dual pully drums and made to look like grapple firing guns. This may be the big rocket launcher used by Robert Muldoon on the Tyrannosaur in the first Jurassic Park novel, but when Muldoon uses the big gun, it takes two hours to take effect on the dinosaur.

Lindstradt Tranquilizer

Eddy Carr (Richard Schiff) is seen using a bolt action tranquilizer rifle with the name "Lindstradt" clearly shown on the side and a thread-on barrel. It is most likely a mock up of a real rifle but the make is hard to tell though The Lost World novel by Micheal Cricton says it was made in Sweden. Ian Malcolm (Jeff Goldblum) is also seen holding this gun in some scenes.

Eddy readies the tranq. rifle when Stegosauruses attack Sarah. It appears to be fitted with an optical sight, which appears to be a first generation Bushnell HOLO-sight.

Eddy attempts to pull up the tranq. gun to use on some T-rexes, but the front blade sight gets stuck in the camouflauge netting, resulting in his demise.

Dan-Inject JM Standard

Some of the hunters are seen using these danish made tranquilizer rifles which are CO2 powered.

Heckler & Koch HK91

Dieter Stark (Peter Stormare) carries a H&K HK91 with an entrylight and telescopic sight attached but is never actually used. Some of the other hunters are also seen using HK rifles and a police sniper is seen hanging out a chopper door with one.

Romanian AKMS

One of the hunters is seen firing an AKMS while being chased by the T-rex. Based on the stock configuration, it looks like a Romanian AKMS.

Searcy Double Barrel Rifle

Roland Tembo (Pete Postlethwaite) keeps a .600 Nitro double barreled rifle, a well known rifle for Elephant hunting, which seems fitting for use on a Tyrannosaurus Rex. Two examples were made for the production of this movie by Searcy in the U.S. Steven Spielberg is said to own one of them himself. The location of the other is unknown, but no doubt in the hands of a collector or hunter. These two examples are "real" and meant to be used, and, as with most high-grade double rifles, their value is in the area of many thousands (over $55,000, given their provenance) of dollars each.

Roland assembles his .600 nitro rifle.

Roland's .600 nitro rifle rests against a tree. His neglect to keep it close leads to Nick Owen (Vince Vaughn) pulling the bullets, leaving useless shells.

Roland aims for the Rex's eye. It should be noted that even if Nick had pulled the bullets, the primers would still make a snap when fired, as opposed to empty clicks. And that a big game hunter may in fact have thought to carry more than the two bullets in the gun itself.

M1911A1

The guards in the San Diego dinosaur zoo are armed with M1911A1 pistols. When attempting to stop Ian Malcom (Jeff Goldblum), Ian says if they really want to stop them, to shoot them.
