A Spanish paleontological team has found more than 700 fish-eating dinosaur footprints in Portugal.
The dinosaurs were believed to be part of the Megalosauridae group, from the Middle Jurassic Period.
In Europe, most fossil remains from this group have been found in France, England and Scotland, while Portugal is known for the high amount of fossilised footprints.

Soaring Ocean Temperature
According to the most comprehensive analysis yet of ocean warming, the soaring temperature of the oceans is the greatest hidden challenge of our generation that is altering the make-up of marine species, shrinking fishing areas and starting to spread disease to humans.
The oceans have already sucked up an enormous amount of heat due to escalating greenhouse gas emissions, affecting marine species from microbes to whales.
The scale of warming in the ocean, which covers around 70% of the planet, is truly staggering.

Vast Reef Discovered
Scientists working with laser data have discovered a vast reef behind the familiar Great Barrier Reef. High-resolution seafloor data provided by LiDAR-equipped aircraft have revealed great fields of unusual donut-shaped circular mounds, each 200-300 meters across and up to 10 meters deep at the center.

Surface Water Shifting
Scientists have found that 115,000 sq km (44,000 sq miles) of land is now covered in water and 173,000 sq km (67,000 sq miles) of water has now become land.
The largest increase in water has been on the Tibetan Plateau, while the Aral Sea has been the biggest conversion of water to land.
Scientists have said that many coastal areas have also changed significantly.
