4-year-old girl walking on beach discovers UK’s most perfectly preserved dinosaur footprint.

"Daddy, what's this?" 4-year-old Lily Wilder from Barry, South Wales, UK took her first step as a scientist this week when she spotted a perfectly preserved dinosaur footprint while walking on the beach. The print measures about 10cm. Scientists believe it was made by a dinosaur about 75cm tall and is about 220 millions years old. The dinosaur species is unknown. Cindy Howells, the Paleontology Curator at Amgueddfa Cymru-National Museum said: "This fossilized dinosaur footprint from 220 million years ago is one of the best-preserved examples from anywhere in the UK and will really aid paleontologists to get a better idea about how these early dinosaurs walked. Its acquisition by the museum is mainly thanks to Lily and her family who first spotted it."

Baby tyrannosaur fossil finally confirms what scientists thought all along – baby T. rex was about the size of a dog.

A team of scientists recently unearthed the fossilized remains of a tiny jaw bone and claw in the United States. 3D scans of the fragments revealed they belonged to tyrannosaurs - the cousins of T. rex. Based on the size of the fossils, it is believed a baby tyrannosaurs would measure about 3-feet long when they hatched - about the size of a Border Collie dog. The findings suggest a tyrannosaurs eggs would measure around 17 inches long. No tyrannosaur dinosaur eggs have ever been found. Tyrannosaurs lived more than 70-million years ago. There are many types of tyrannosaurs including the popular Tyrannosaurus rex. They had large skulls, foreword facing eyes, and humorously short arms.

New dinosaur king – Spinosaurus towered over Tyrannosaurus rex and ate pretty much anything that got in its way

Spending most of its time swimming in water, the newly discovered Spinosaurus gobbled up sharks and alligators whole. It had paddle-like feet, short, dense leg bones, sealable nostrils that allowed it to swim underwater, massive, backward-slanted cone-shaped teeth, and a huge 6-foot sail on its back that would have risen from the water like a shark’s fin (it somewhat resembled a giant alligator with a long neck). Oh, and it was about ten feet *bigger* than the previous dinosaur king - Tyrannosaurus rex. The first Spinosaurus was actually discovered in the Egyptian desert in 1912 but a bombing of Munich, Germany in World War II destroyed the bones before scientists could really study the huge meat-eating dinosaur. Then a new Spinosaurus specimen was discovered in the

Record breaker – researchers discover world’s largest dinosaur in Argentina

Scientists have been digging at the site for over three years now and have finally hit pay dirt (pay dirt… digging… get it? I’ll show myself out now…). Researchers have unearthed what they believe is the largest dinosaur ever and the biggest animal ever known to have walked the earth. The creature is estimated to weigh almost 80 tons (as much as 14 elephants) and stand over 65 feet tall (that’s almost as tall as a seven-story building). From its head to the tip of its tail measures 130 feet – about half the length of a football field! The gigantic specimen was found in the Patagonia region of Argentina, a hot spot for dinosaur fossils, at a site that researchers have been digging for over

Diplodocus dinosaur

The name of this dinosaur is Diplodocus. It is a plant eater and is part of the brontosaurus family. Diplodocus means "double beam".  It belongs to a group of dinosaurs called sauropods. It grew about 30 feet tall (that's as tall as a 3-story building). Diplodocus had to watch out for allesaurus' because Diplodocus might get eaten.  It is one of the most easily identifiable dinosaurs, with its classic dinosaur shape, long neck and tail and four sturdy legs. Diplodocus as well as many of the other dinosaurs probably spent a good part of their time in the water, where they fed upon water plants and escaped their natural enemies, the carnivorous dinosaurs (meat eating meanies) living at the same time. There are a number of
