How big is Rhamphorhynchus?
1.25 metres!
A genus of long-tailed pterosaurs from the Late Jurassic (about 150 million years ago). With a wingspan of approximately 3–6 feet (1–2 meters), Rhamphorhynchus had a lightweight body, long jaws with sharp teeth, and a distinctive diamond-shaped vane at the end of its tail. It likely fed on fish, using its long teeth to snatch prey from the water while in flight.
Dodo Bird
The dodo bird went extinct sometime during the 1600s. The name comes from the sound they make (or should I say used to make since they're now extinct). So yeah, they're gone.
FM Radio Wavelength
F and M are the sixth and thirteenth letters of the alphabet. Six is a perfect number, while thirteen is not. We all have our differences, and we have to learn to accept them. That's the only way we'll live in harmony.
Rafflesia
The Rafflesia is the largest single flower in the world. It can weigh up to 10 kilograms, which is actually pretty heavy. The flower smells like rotting flesh to attract flies, which will pollinate it.
Human
I'm going to assume you are a human. I am a human too! Did you know that there are almost 8 billion of us? That's a lot. In fact, if you met each person for one second, it would take you about 200 years to meet all of them! Better get started now!
Psittacosaurus
A small, parrot-beaked ceratopsian dinosaur from the Early Cretaceous (approximately 125–100 million years ago). It measured about 6.5 feet (2 meters) in length and weighed around 44 pounds (20 kilograms). Known for its distinctive short beak, similar to a parrot's, Psittacosaurus was a herbivore, feeding on tough vegetation. Some species had long filament-like structures on their tails, which might have been used for display.
Wandering Albatross
The Wandering Albatross is the bird with the largest wingspan! They fly almost all the time, only stopping to eat and make babies. Their population is slowly decreasing. Now it is only at 26,000, which isn't very much.
