Scientists found new type of dinosaur

Couple of days ago, excavator in central Thailand announced new type of land dinosaur has been found. The fossils were uncovered between 2008 and 2013 as part of a joint project with the Fukui Prefectural Dinosaur Museum in Japan. It is one of the biggest discoveries of the decade paleontologists say. Called Siamraptor suwati,it is one of the most complete dinosaurs ever found.Why is this dinosaur interesting is because it is discovered that this kind had teeth like modern sharks,which is of course sea creature and it has nothing in common with this ancient predator.This creature was 25 feet long(almost 8 meters) and was roaming the Earth some 10 millions years before first appearance of famous T-Rex. The bones of Siamraptor include parts of the spine, hips, feet, hands and skull. . At the place where Siamraptor was found, there are many carcharodontosaur teeth that match those of the newly named predator. Given that dinosaurs shed teeth throughout their lives, including when they ate, the Ban Saphan Hin site appears to have been a Siamraptor stomping ground.

From the bones showed in picture above,paleontologists managed to find exact look of the dinosaur,which actually resembles T-Rex,except this had larger upper body ratio and is overall smaller.Researcher at Thailand’s Nakhon Ratchasima Rajabhat University, pored over the bones and found that the skeleton is shot through with air sacs. This would have made the dinosaur’s frame lightweight and perhaps helped it breathe faster, an idea that future scans of the bones could put to the test.

In Cambodia, sand mining is big business — but it comes at a price

Sand mining accounts for 85 percent of all worldwide mineral extraction, a $70 billion industry. In Cambodia, the practice is big business — but it comes with a price. The country relies upon the Mekong River for commerce and transportation, but extensive dredging to harvest sand is fundamentally changing its ecosystem and eroding its banks.

Portugal : A case of migration with impressive geographical consequences

If you didn’t know it Portugal has a population of around 10 millions inhabitants. in comparison Switzerland has almost the same population with only half of the size of the country. What makes Portugal an interesting case of study in geography ? Well there are over 40 millions Portuguese people around the world. 30 all around the world and 10 in Portugal itself. So only 1/4 of Portuguese people live in Portugal. So how the hell did this happen ?

After the loss of its colonies Portugal struggled a lot economically. Moreover the country didn’t caught the train to modernize its infrastructures for the post-colonialist period. Because they didn’t made the economical transition during the 20th century, the country became one of the poorest in europe. As a consequence a lot of Portuguese decided to migrate to find better opportunities in the old colonies, in France, Luxembourg, Switzerland, the US and in Uk (which is allied with Portugal since the 14th century). If you ever visit Portugal and go outside the big cities and tourism spots, one thing which will shock you is the number of buildings which are decaying and the number of ghost towns and villages you will encounter. In comparison with the rest of Europe, there are a lot of cities and villages which are partially inhabited like (estimation) 20% of houses being used by actual residents and 80% which are from Portuguese living outside the country.
