| Fallen Kingdom |
The talk was a masterclass in creature animation, demonstrating how much careful research goes into the creation and animation of the dinosaurs.
The Jurassic World series of movies as are a "balance between science and entertainment", as the film-makers try to keep both audiences and paleontologists happy.
From the point of view of animators looking to tackle realistic dinosaur animation, the lesson is simple: use as much reference as you can, and make sure you use live action reference that is as close as possible to the anatomy of the creatures you are trying to animate.

| Baby Emu |
Of course, no-one knows how dinosaurs actually moved. But, dinosaurs have plenty of living relatives, such as ostriches and emus, so useful reference material can be found throughout the natural world.
The ILM animators got hold of a baby emu and filmed it, using the performance as source material for the baby raptors. So when you are watching the baby raptors in Fallen Kingdom, you are basically looking at a baby emu.
Live action reference
Animators did early run cycles on "Blue", one of the raptors, keeping Blue's head almost completely still, while the rest of the body is running, its eyes constantly focusing on its prey. The animation was based on motion studies of a cheetah, a fast predator whose head remains locked in position to enable to cheetah to keep its prey constantly in its line of sight.
The Importance of Research
The animators did lots of research, looking at alligators and lizards, and recording sounds and capturing footage. Alligators, for example, vibrate their throats when they make threatening sounds, and this animation was used to help create the Indominus Rex.
Indoraptor
The indoraptor was a genetically engineered animal that "needed to feel abused and neglected". The dinosaur's skin textures needed to be damaged and beaten up, and the idea behind the character was that it had been a caged animal, poorly treated.

The run cycle on "Indo" was based in part on ostriches, though when matched too closely to an ostrich run it "looked ridiculous". Live action reference should be used as source material, but usually cannot be followed too literally.
Anatomically, Indo was very different to earlier Jurassic World dinosaurs, and each new dinosaur has to be discovered as a fresh character, with a unique way of moving and behaving.
Animation is an iterative process. Animators get feedback from their colleagues, from animation leads, from animation supervisors. Everyone is trying to "get inside the director's head" and try to find the perfect performance that the director will be looking for.
Tail animation on the dinosaurs is a "long and painful process", but the ILM animators have in-house tools to help get the tail animation right. It's not exactly a simulation, but a physics-based approach that saves the animators from having to hand keyframe the overlapping action frame by frame.

| Komodo dragon - great reference |
The animators also researched komodo dragons, in part for their reptilian surface textures, but also to see how they move. Komodo dragons fight one another for mating rights, and these fights can be extremely vicious.
Komodo dragons also have nasty strings of saliva dangling from their mouths, so the animators borrowed this for a close-up of the carnosaur in Jurassic World to get an especially disgusting look.
Research is important because nature can be complex and unexpected. Even apparently basic things - such as a simple blink - can be full of complexity.
No-one knows exactly what dinosaur skin looks like, though surviving fragments suggest skin much like modern lizards. So the team researched modern reptiles such as geckos and monitor lizards to get the surface textures right.
Dynamics -v- key frame animation
And just in case you were thinking that the muscles and skin were all animated with dynamics and simulations, in fact much of the work was done by the keyframe animators, hand-animating the fat and muscles using a variety of control curves.
Dinosaurs at Escape Studios
We're no strangers to dinosaurs here at Escape Studios. To see some excellent dinosaur animation, check out "Tokyo Rex", the work of Escape Studios' animation tutor, Lee Caller, below.
