   How was the real past different?

   A movie shows people running away from a living T. rex.

   • T. rex lived long before humans appeared.
   • Early humans hunted T. rex with simple tools.
   • T. rex disappeared shortly after the first humans appeared.

   Show solution

   • T. rex lived long before humans appeared.

   Movies sometimes mix time periods. T. rex died out millions of years before humans appeared.

   Mit evett főként a Triceratops?

   Triceratops had three horns, a large head, and a sharp beak.

   • Other dinosaurs
   • Plants
   • Fish

   Show solution

   • Plants

   A szarvai nem tették húsevővé. Csőrével növényeket vágott le, fogaival pedig kisebb darabokra aprította őket.

   Mely állatok tartoznak a dinoszauruszok ma is fennmaradt csoportjába?

   Most dinosaur groups died out long ago, but one group is still alive.

   • Lizards
   • Crocodiles
   • Birds

   Show solution

   • Birds

   A madarak kis termetű, húsevő dinoszauruszokból fejlődtek ki. A veréb a dinoszauruszok családfájának része.

   Mik voltak a pteroszauruszok?

   Pterosaurs had wings and lived at the same time as many dinosaurs.

   • Flying reptiles related to dinosaurs
   • Dinosaurs with wings made of feathers
   • Early birds with unusually large beaks

   Az, hogy az állatok ugyanabban az időben éltek, nem jelenti azt, hogy ugyanabba a csoportba tartoztak.

   Show solution

   • Flying reptiles related to dinosaurs

   A pteroszauruszok külön csoportot alkottak. Szárnyaik nem tollakból, hanem bőrből álltak.

   What do fossils tell us about the real animal's height?

   Movies often show a Velociraptor standing as tall as an adult.

   • It was much taller than an adult.
   • It was about as tall as an adult.
   • It was much shorter than an adult.

   Show solution

   • It was much shorter than an adult.

   A real Velociraptor stood roughly knee-high. Its long tail made it much longer than it was tall.

   A dinoszauruszok életét bemutató melyik kép illik ezekhez a felfedezésekhez?

   Dinosaur fossils occur in rocks formed in ancient deserts as well as forests.

   • All dinosaurs lived in wet swamps.
   • Different dinosaurs lived in different environments.
   • Dinosaurs could live only beside the ocean.

   Show solution

   • Different dinosaurs lived in different environments.

   A filmekben látható dzsungelek csak egy lehetséges környezetet mutatnak be. A dinoszauruszok sokféle helyen éltek.

   What does this discovery tell us about feathers?

   A fossil of a small dinosaur shows that it had feathers, but its arms were too short for flight.

   • Having feathers did not always mean an animal could fly.
   • Every dinosaur with feathers could fly.
   • Feathers appeared only after dinosaurs died out.

   Show solution

   • Having feathers did not always mean an animal could fly.

   Feathers can also help keep an animal warm. Flight is not their only use.

   Találkozhatott volna ez a két dinoszaurusz a vadonban?

   Stegosaurus lived in the Jurassic period. T. rex lived much later, in the Cretaceous period.

   • Yes, because all dinosaurs lived at the same time.
   • Yes, if they lived beside the same river.
   • No, because they lived at different times.

   Az időszakokat hasonlítsd össze, ne a helyeket.

   Show solution

   • No, because they lived at different times.

   A dinoszauruszok kora nagyon hosszú ideig tartott. Sok közismert dinoszaurusz soha nem élt egy időben.

   Which event does this evidence support?

   Scientists found a huge impact crater in Mexico and material from the impact in a rock layer found around the world.

   • A long ice age dug out the crater.
   • A large asteroid hit Earth.
   • A series of volcanoes formed the impact crater.

   Show solution

   • A large asteroid hit Earth.

   The impact sent dust into the sky. Less sunlight killed off plants and helped cause a mass extinction.

    Hogyan válik sok föld alá került csont fosszíliává?

    Many dinosaur fossils feel more like rock than fresh bone.

    • Minerals fill spaces or replace material in the bones.
    • Heat melts the bones into new rock.
    • The bones dry out and remain completely unchanged.

    Show solution

    • Minerals fill spaces or replace material in the bones.

    A föld alatti víz ásványi anyagokat juttathat a föld alá került csontokba. Ez a folyamat több millió éven át megőrizheti az alakjukat.

    What does this fossil show about the dinosaur's teeth?

    A dinosaur jaw has a small new tooth growing below an older tooth.

    • It had only one set of teeth for its whole life.
    • It was losing all its teeth permanently.
    • New teeth could replace older teeth.

    Show solution

    • New teeth could replace older teeth.

    Many dinosaurs replaced their teeth throughout their lives. People normally have only two sets.

    How did these dinosaurs probably hold their tails while walking?

    Many sets of dinosaur tracks show clear footprints but no marks from a tail.

    • They dragged their tails behind them.
    • They held their tails off the ground.
    • They rested their weight on their tails with each step.

    Think about what would leave a mark between the footprints.

    Show solution

    • They held their tails off the ground.

    Old pictures often show dinosaurs dragging their tails. A raised tail could help a two-legged dinosaur balance.

    Mit becsülhetnek meg a tudósok ezeknek a gyűrűknek a segítségével?

    Some dinosaur bones contain growth rings, a little like the rings inside tree trunks.

    • How old the animal was when it died
    • How many meals the animal ate
    • How many eggs the animal laid

    Show solution

    • How old the animal was when it died

    A növekedés az év egy részében lelassulhat, vonalat hagyva a csont belsejében.

    What do these marks show on their own?

    Scientists found T. rex tooth marks on the bones of a plant-eating dinosaur.

    • The T. rex must have killed this animal itself.
    • T. rex only ate animals that were already dead.
    • The T. rex may have bitten it before or after it died.

    A bite mark does not tell us exactly when the bite happened.

    Show solution

    • The T. rex may have bitten it before or after it died.

    Many meat-eating animals both hunt and eat animals they find already dead. Bite marks alone cannot tell those behaviors apart.

    What do scientists know about how a T. rex really sounded?

    A movie gives a T. rex a deep, lion-like roar.

    • Its size proves that it roared like a lion.
    • What it actually sounded like is still unknown.
    • Its teeth tell us exactly how its roar sounded.

    Show solution

    • What it actually sounded like is still unknown.

    Living relatives, such as birds and crocodiles, offer clues about possible sounds. A movie roar is still a creative choice.
