A fossil animal locked in Lebanese limestone has been shown to be an extremely precious discovery - a snake with two legs.
Scientists have only a handful of specimens that illustrate the evolutionary narrative that goes from ancient lizard to limbless modern serpent.

Fossil hunters have found the remains of ancient mammals that were related to today's rabbits and hares.
The 53-million-year-old specimens consist of small ankle bones unearthed in Gujarat, central India.
They belong to early examples of an animal group called lagomorphs, which today comprises hares, rabbits and a hamster-like animal called a pika.

 A frog the size of a bowling ball, with heavy armour and teeth, lived among dinosaurs millions of years ago - intimidating enough that scientists who unearthed its fossils dubbed the beast Beelzebufo, or Devil Toad.
But its size - 10 pounds and 16 inches long - isn't the only curiosity. Researchers discovered the creature's bones in Madagascar. Yet it seems to be a close relative of normal-sized frogs who today live half a world away in South America, challenging assumptions about ancient geography.
The discovery, led by palaeontologist David Krause at New York's Stony Brook University, was published Monday by the journal Proceedings of the National Academy of Sciences.

Rosida Asmi never thought she would find the fossil of a prehistoric animal while doing her laundry in Gandu River, close to her home in Terban village, Jekulo district, in the Central Java town of Kudus.
On Dec. 20 last year, a dull-colored white piece of wood protruding from the river caught her attention.
She poured some water on it and was surprised. Half convinced, the 14-year-old high school thought she had found a fossil.

Bat fossil

A fossil found in Wyoming has resolved a long-standing question about when bats gained their sonar-like ability to navigate and locate food.
They found that flight came first, and only then did bats develop echolocation to track and trap their prey.
A large number of experts had previously thought this happened the other way around.
Details of the work by an international team of researchers is published in the prestigious journal Nature.

Fossils from the Western Region of Abu Dhabi Emirate are the main focus of a project initiated by the Abu Dhabi Authority for Culture and Heritage (ADACH) and the Yale University in USA.
The recent works of this cooperation were detailed in a lecture held at the Abu Dhabi Cultural Foundation on Tuesday by Yale Professor Andrew Hill.
According to him, the ADACH-Yale project is meant to carry out research on the Baynunah Formation, a set of geological deposits rich in fossils, dating between six and eight million years ago, were exposed in the Western Region.
The recovered fossils, along with geological investigations, show a picture of Abu Dhabis ancient environment that was quite a lot different from its modern hyper-arid desert landscape.
In the late Miocene epoch, Abu Dhabi featured a large system of shallow rivers that supported a diverse ecosystem, including hippopotamus, crocodiles, turtles, and catfish.

Palaeontologists have discovered a fossil specimen in southeastern Morocco, which has solved the mystery about the origin of an extinct group of slug-like animals that existed 305 to 485 million years back.
Known as a machaeridian, an invertebrate, or animal without a backbone, this creature had rows of mineralised armour plates on its back.

Discovery of an exceptional fossil specimen in southeastern Morocco that preserves evidence of the animals soft tissues has solved a palaeontological puzzle about the origins of an extinct group of bizarre slug-like animals with rows of mineralised armour plates on their backs, according to a paper in Nature.
While evolution has produced great diversity in the body designs of animals, over the course of history several highly distinct groups, such as trilobites and ammonites, have become extinct. The new fossil is of an unusual creature known as a machaeridian, an invertebrate, or animal without a backbone, that existed for about 180 million years from 485 to 305 million years ago.

Shell Lake Mayor Dave Zeug came up with an amazing find, while picking up trash along the city's namesake body of water.
The Washburn County Register reports that Zeug initially picked up an item last fall that he thought was a heavily corroded screw-in metal bolt, but after further thought, he decided that wasn't the case, so he solicited the expertise of UW-La Crosse staff to analyse the mysterious object.
Turns out, he had actually found a fossil of an ancient squid-like creature with a crusty shell called a cephalopod.
