1. What prehistoric bird had a wingspan up to 11 meters?
2- What ancient sea creature had a spiral shell and is related to modern nautiluses?
1. Argentavis magnificens
Argentavis magnificens was a giant bird from the Miocene era, with a wingspan estimated between 6 and 7 meters. These birds likely soared above open woodlands, using warm air currents to stay aloft for long periods.
2- Ammonites
Ammonites were cephalopods that lived in the oceans from the Devonian to the Cretaceous period. They had a coiled shell that provided buoyancy and protection, similar to modern nautiluses.
3- What large mammal roamed North America during the Pleistocene epoch with curved tusks?
4- Which ancient reptile, often mistaken for a dinosaur, lived in the seas during the Mesozoic era?
3- Woolly Mammoth
Wooly mammoths were herbivorous giants that lived during the last Ice Age. They adapted to cold climates with their thick fur and long tusks, which were likely used for defense and obtaining food.
4- Plesiosaur
Plesiosaurs were marine reptiles with long necks and paddle-like limbs. They were not dinosaurs but lived alongside them, hunting fish and other marine creatures.
5- What is the name of the prehistoric shark with a distinctive spiral tooth shape?
6- What ancient flying reptile had a wingspan of over 10 meters in the Late Cretaceous?
5- Helicoprion
Helicoprion had a unique tooth-whorl structure that resembled a circular saw. It likely used this adaptation to slice through prey in the oceans of the Permian and Triassic periods.
6- Quetzalcoatlus
Quetzalcoatlus was one of the largest known flying animals, resembling a modern pterosaur. It likely scavenged for food and may have been capable of short bursts of powered flight.
7- Which extinct marsupial, native to Australia, was the largest carnivorous mammal?
8- What ancient marine reptile, often called a "sea dragon," lived during the Jurassic period?
7- Thylacoleo carnifex
Thylacoleo carnifex, also known as the marsupial lion, was a powerful predator that lived during the Pleistocene epoch. It had strong jaws and sharp teeth, possibly hunting large prey like giant kangaroos.
8- Plesiosaurus
Plesiosaurus was a long-necked marine reptile that swam in ancient seas. Its streamlined body and paddle-like limbs suggest it was a strong swimmer, hunting fish and other aquatic prey.
9- What is the name of the prehistoric horse with three toes in the Eocene epoch?
10- Which extinct relative of modern elephants had long, straight tusks in Europe and Asia during the Pleistocene?
9- Eohippus
Eohippus, also known as Hyracotherium, was an early ancestor of modern horses. It was small, about the size of a dog, and had three toes on its front feet and four toes on its hind feet.
10- Straight-tusked Elephant
The Straight-tusked Elephant, Palaeoloxodon antiquus, was a large herbivore with elongated tusks. It likely fed on a variety of vegetation and was part of the megafauna that existed during the last Ice Age.
