The oldest plesiosaur was a strong swimmer

Plesiosaurs were especially effective swimmer. These long extinct "paddle saurians" propelled themselves through the World's oceans by employing "underwater flight" -- similar to sea turtles and penguins. Paleontologist, now describe the oldest plesiosaur, together with colleagues. The find comes from the youngest part of the Triassic period and is about 201 million years old, according to Science Daily.

Instead of laboriously pushing the water out of the way with their paddles, plesiosaurs were gliding elegantly along with limbs modified to underwater wings. Their small head was placed on a long, streamlined neck. The stout body contained strong muscles keeping those wings in motion. Compared to the other marine reptiles, the tail was short because it was only used for steering. This evolutionary design was very successful, but curiously it did not evolve again after the extinction of the plesiosaurs" says paleontologist Prof. Martin Sander.

Dracula ticks in amber tell ancient blood-sucking tale

Feathered dinosaurs were covered in ticks just like modern animals, fossil evidence shows.

Parasites similar to modern ticks have been found inside pieces of amber from Myanmar dating back 99 million years.

One is entangled with a dinosaur feather, another is swollen with blood, and two were in a dinosaur nest, according to BBC.

Scientists say the discovery, which has echoes of Jurassic Park, is the first direct fossil evidence that ticks fed on the blood of dinosaurs.

Talking to ourselves and voices in our heads

As far our brain is concerned, talking to ourselves in our heads may be fundamentally the same as speaking our thoughts out loud, new research shows. The findings may have important implications for understanding why people with mental illnesses such as schizophrenia hear voices.

Scientist and study first author Thomas Whitford says it has long been thought that these auditory-verbal hallucinations arise from abnormalities in inner speech -- our silent internal dialogue, according to Science Daily.

The migration of Golden eagle

Golden eagles in North America may have the timing of their migration shifted out of step with a seasonal boom in food they need to raise their young, according to scientists.

A project to track the impact of climate change on migrating animals has revealed that adult golden eagles are unable to shift the timing of their migration, according to BBC.

Lead researcher Scott LaPoint presented the findings at the annual meeting of the American Geophysical Union.

Bronze Age iron weapons ‘came from outer space’, claims new study

A new study claims that most of the iron used in weaponry and Artefacts dating from the Bronze Age is, in fact, of extraterrestrial origin. It further explains how our ancient ancestors were able to use the metal without access to smelting, according to RT.

The new research, led by French scientist Albert Jambon used geochemical analyses to differentiate Earthly and extraterrestrial metals found in a range of Bronze Age artefacts from across the world.
