Discovered, World's Smallest Dinosaur

A fossil animal that resembles a bird found in the area of ​​southern England. The fossil was suspected bird-like dinosaur bones.

As quoted from livescience.com, this finding was reported by Paleozoologis from the University of Portsmouth, Darren Naish in August last year and published in the journal Cretaceous Research.

This dinosaur was named Ashdown, according to the place of fossil discoveries. Dinosaurs are believed to live more than 100 million years ago and has a height no more than 40 cm. Ashdown, probably the smallest dinosaur species that ever lived on earth.

Fossil bones found in the form of a small neck with a length of about 7.1 millimeters. The bones were thought to belong to Ashdown adult dinosaur that lived during the Cretaceous period, about 145 million to 100 million years ago. Bones belonging maniraptoran, this theropod dinosaur group, believed to be the embryo of birds today.

Looking for the real size dinosaur with only examined one bone is very difficult. However, according to Naish, the researchers used two methods to find out how much Ashdown. The first method to create a digital model dinosaur's neck. Then match it with the shadow of digital neck maniraptoran in general. However, this method tends to use more elements of the scientific art.

While the second method, through a more mathematical approach by using the ratio of the neck to the body of another dinosaur to calculate the length of this new maniraptoran. Based on the report made Naish, both methods get results, new maniptoran has a length of approximately between 30 to 50 centimeters.

If dinosaurs were found in this Ashdown break record with the smallest, he would beat the smallest dinosaur that ever lived in North America, Anchiornis. It also resembles a dinosaur and bird life in what is now a region of China at 160 million to 155 million years ago. If standing, reaching 50 cm tall and weighed about 2 kg
