A model of a life-size Tyrannousaurus Rex
Dinosaur fossils found in China have got scientists pretty excited as they say they’ll help them learn loads more about the ferocious Tyrannosaurus Rex.
Found near the city of Jiayuguan, the remains are from a type of tyrannosaur being called Xiongguanlong baimoensis.
The name may be a bit of a mouthful, but it’s thought the fossils could provide the missing link between the huge T Rex and its smaller ancestors.
They date from part of the Cretaceous period – about 100 million years ago.

Did you know? The Great Garbage Patch

Much of our plastic ends up floating in the North Pacific

In 1997 Captain Charles Moore, founder of the Algalita Marine Research Foundation, set sail from Hawaii and discovered, in a remote part of the North Pacific, an island…made of plastic.
Moore measured about 300,000 tiny pieces of plastic per square kilometer back then, but a decade later there are approximately 2.3 million pieces of plastic per square kilometer. What is known as the Great Pacific Garbage Patch is now the size of the United States, according to Moore.

Wind and ocean currents sweep up this garbage and deposit it in this slow-moving gyre.

Did you know? When is a second not a second?

Most of us know that a second is a unit of time. There are sixty seconds in a minute and sixty minutes in a hour.

However, the term second is also a term used in measuring angles. Angles are usually measured in degrees. However, like most measurements, we can get very precise. Degrees are divided into 60 minutes (1 degree = 60 minutes) and minutes are further divided into seconds (1 minute = 60 seconds).

In mapping on a global scale, precise measurement is key. A difference of 1 second of longitude or latitude is over 100 feet (depending on terrain).

Did you know? Today is Pi Day
