There's a Velociraptor called The Big One in Jurassic Park, who was the alpha. There's also another called Clever Girl, which wasn't really an official name until it was recently added in Jurassic World Alive - by that I mean the staff at the park would not have called her that, but it has become her name since. In the storyboard of the kitchen scene the Velociraptor puppeteers are listed as Kim and Randy, but the names have since been attributed to the raptors. However, because there is no difference in the appearance of the raptors it is difficult to tell which of the four names should be assigned to which of the three raptors, although obviously Clever Girl is the one that kills Robert Muldoon. The male T.rex from The Lost World is referred to as a "Buck" by Roland Tembo, so the name stuck. Because the male is called Buck, the female has been nicknamed Doe. The baby T.rex is referred to as Junior in one of the Kenner toy lines. The Spinosaurus in Jurassic Park 3 doesn't have a name in the movie, but if it is the same one that appears in Camp Cretaceous (which it probably is) then it is referred to as Asset 87, although only after being captured by Mantah Corp. The male Velociraptors have been given the nickname Quilliam by fans, although this isn't official. The rest of the Jurassic World Velociraptor Pack are Charlie (the green one with darker stripes), Delta (the teal-grey one) and Echo (the brown one with dark blue stripes). In Dominion, Beta is the name of Blue's asexually reproduced baby. The Atrociraptors all have unique names as well: Ghost (the white one), Red (the copper orange-red one with tan stripes), Tiger (the orange and black striped one), and Panthera (the orange one with a pale underbelly). The Carnotaurus in the Malta sequence has been nicknamed Demon by fans, due to having a similar red and black colouration to one of the Kenner toys, which was also called Demon. In Camp Cretaceous there is Bumpy the Ankylosaurus, the Baryonyx trio Grim, Chaos and Limbo; and the two baby Spinoceratops Rebel and Angel. The original Scorpios Rex is codenamed E750.
