The remains of a little crab was found in fossilized amber (tree resin). The remains, dating back 100 million years, were found in the country of Myanmar. Called Cretapsara athanata, the crab that lived during the time of the dinosaurs, is believed to be the the best such crab fossil ever found. The amazing discovery, made in 2015, was being sold by a street vendor in a city in Myanmar.

Paleontologists have discovered a long ago sea scorpion that was the size of a dog! The fossilized remains were unearthed in China. Called Terropterus xiushanensis, the arthropod lived about 435 million years ago. Related to horseshoe crabs, the massive sea scorpion was about 3.3 ft. long. It is thought that the creature used their long claws lined with teeth for catching prey.

How many walrus are on the planet? If you'd like to help count them, you can do so right from your living room. Using satellite images, volunteers are being asked to scan images to help count their numbers. The WWF (World Wildlife Federation) with the British Antarctic Survey have started a five year program called "Walrus from Space".Tracking of albatross, seals, penguins and even whales have been spotted from space but this is the first time the satellite images will be used to count walrus, specifically the Atlantic sub-species. Global warming and decreased sea ice (used by walrus for raising their babies and to hunt), is having a negative effect on the walrus population.
