How big is Roble?

One of the most famous and fearsome dinosaurs, T. rex lived during the Late Cretaceous (around 68–66 million years ago). As an apex predator, it measured up to 40 feet (12 meters) in length, stood about 13–15 feet (4–5 meters) tall at the hips, and weighed between 9–14 tons. It had powerful jaws lined with teeth capable of crushing bone, a robust skull, and tiny but functional arms. Its diet included large prey like hadrosaurs and ceratopsians.

A genus of large theropod dinosaur from the Late Cretaceous (approximately 70 million years ago) discovered in modern-day Patagonia. Named Maip macrothorax, it was a member of the megaraptorid family and measured around 33 feet (10 meters) long, and 11.4 feet (3.5 meters) wide. Maip was a fast predator, with large claws on its hands, slender legs, and a probable covering of protofeathers.

Estamos hablando de una mole de 15.000 kg. Resulta impresionante pensar que algo así aterrizó en la Luna. Su hazaña inspiró el videojuego Lunar Lander, que, por cierto, es extremadamente difícil. Cuando jugamos, a menudo nos quedamos sin combustible antes de aterrizar.

La ballena azul es el animal más grande que existe. Puede alcanzar las 180 toneladas métricas, superando a cualquier otro animal conocido. Lamentablemente, la caza ha reducido su población de 300.000 a apenas unos 2.000 individuos.

El Amphicoelias fragillimus fue el dinosaurio más grande del mundo. Se estima que podía superar las 100 toneladas de peso. Era tan grande que podrías incluso construir tu casa sobre él.

A colossal sauropod dinosaur from the Late Cretaceous (about 100 million years ago), closely related to Argentinosaurus. Found in Patagonia, it is estimated to have reached lengths of up to 122 feet (37 meters) and weighed 55–77 tons. It was a slow-moving herbivore, relying on its size for protection against predators.
