Scientists used a laser scanning system to produce a detailed, 3-D model of the sauropod Argentinosaurus. So, researchers typically reconstruct a dino’s muscles and tendons based on what they see in living creatures today. Such soft tissues normally don’t get preserved as fossils (the way that bones sometimes do). This process is guided by subtle features on well-preserved fossils that indicate the size and location of a creature’s muscles and tendons. Then, the scientists add meat to the bones (virtually, of course). These remains can provide an idea of a creature’s overall size and shape. These are the preserved remnants of the dinosaurs - or the footprints and other traces they left behind. They’re portrayed realistically, informed by science.įirst, researchers start with fossils. But unlike in your parents’ day, these dinos aren’t depicted cartoonishly.
Yet these ancient creatures live, breathe and rampage across the screen in movies like Jurassic Park and TV series like BBC’s Primeval. That’s long before any humans were around to observe their behaviors. Dinosaurs have been extinct for more than 65 million years.
