Dinosaurs were scaly, grey-green reptiles like in Jurassic Park
Many dinosaurs were feathered, colourful, and held their tails differently
Brontosaurus doesn't exist, it was always called Apatosaurus
Brontosaurus was reclassified, then resurrected as a valid genus
Dinosaurs and humans coexisted on Earth
Dinosaurs went extinct 66 million years before humans evolved
Velociraptors were human-sized predators
Velociraptors were turkey-sized; Jurassic Park heavily exaggerated their size
The Brontosaurus Is an Invalid Dinosaur Name
Brontosaurus restored as valid genus in 2015
All Dinosaurs Lived at the Same Time
Dinosaurs spanned over 165 million years of evolution
T. rex was a pure apex predator that only hunted live prey
Evidence suggests T. rex was an opportunistic feeder, scavenger and hunter
All dinosaurs were enormous creatures
Most dinosaurs were chicken-sized to house-sized, not all giants
Dinosaurs were slow, lumbering, cold-blooded reptiles
Many were active, relatively fast, and likely warm-blooded or mesothermic
All dinosaurs went completely extinct 66 million years ago
Birds are dinosaurs, they never went extinct, just evolved
Dilophosaurus had a frill and could spit venom
No evidence for frills or venom, a Jurassic Park invention
Stegosaurus had a brain in its butt
Stegosaurus had a spinal nerve complex but only one brain, in its head
T. rex couldn't see you if you stood still
T. rex had excellent vision, including movement detection
Jurassic Park's DNA-from-amber premise is biologically possible
While mosquitoes preserve in amber, dinosaur DNA recovery remains impossible
Dinosaurs lived during the Ice Age
Dinosaurs went extinct 66 million years ago; Ice Ages were recent
Pterodactyls were dinosaurs
Pterosaurs were flying reptiles but not dinosaurs, a distinct group
Plesiosaurs were dinosaurs
Plesiosaurs were marine reptiles, a separate group from dinosaurs
Dinosaurs were failures that went extinct due to poor adaptation
Dinosaurs dominated Earth for 165 million years, far more successful than mammals
Dinosaurs lived in swamps because they were too heavy for land
Most dinosaurs thrived on dry land; swamp dwellings were rare
T. rex had tiny, useless arms
T. rex arms were powerful and likely used for gripping and feeding
Spinosaurus was just a bigger T. rex
Spinosaurus was a distinct aquatic dinosaur with unique features and lifestyle
An asteroid was the sole cause of dinosaur extinction
Asteroid impact combined with volcanism created perfect extinction conditions
Dinosaurs were grey, brown, and green
Dinosaurs displayed diverse colours including reds, oranges, blues, and iridescent hues
Dinosaurs dragged their tails on the ground
Most dinosaurs held tails elevated and horizontal for balance
All dinosaurs were meat-eating carnivores
Most dinosaurs were herbivores; only about 25% were carnivorous
Sauropods needed to live in water to support their massive weight
Sauropods were terrestrial; skeletal features show land-based weight support
Dinosaurs were silent creatures that made no vocalizations
Evidence suggests dinosaurs made vocalizations for communication
Raptors hunted in coordinated packs like modern wolves
Pack hunting evidence is speculative; solitary/family group hunting more likely
Triceratops and Torosaurus are the same dinosaur
Initially synonymized but likely separate, still debated
Megalodon sharks lived at the same time as dinosaurs
Megalodon emerged 20+ million years after dinosaurs went extinct
Dinosaurs were reptiles like modern lizards and snakes
Dinosaurs were a distinct group, modern reptiles are more distantly related
Dinosaurs couldn't swim
Many dinosaurs were capable swimmers, including semi-aquatic species
Pachycephalosaurus used its dome head for head-butting combat
Dome likely served display functions; head-butting role remains uncertain
T. rex had smooth scales like modern lizards
Recent skin impressions show varied texture; many theropods had feathering
The Bone Wars created widespread dinosaur classification errors that stuck for decades
Marsh and Cope's competition led to hasty descriptions, some later revised
Iguanodon's thumb spike was originally placed on its nose
An early reconstruction error that was eventually corrected
Crystal Palace dinosaur sculptures shaped wrong expectations for 150 years
1854 sculptures perpetuated outdated reconstructions that influenced popular culture
Dinosaurs went extinct suddenly overnight due to asteroid impact
Extinction occurred over years to decades, with ecosystem collapse rather than instant death
Dinosaur extinction was caused by volcanism, not an asteroid
Evidence supports both factors working together, not volcanism alone
All large Mesozoic animals were dinosaurs
Pterosaurs, plesiosaurs, mosasaurs, and mammoths were not dinosaurs
