Skeleton-like formations of Martian rocks are teasing the Internet

The fish bone-like rock formations photographed by NASA’s Curiosity rover on Mars sparked excitement on the Internet, with some netizens dubbing them “dragon bones”.

The rocks have been imaged in recent weeks by the rover in Gale Crater on Mars. The structures look like a series of bars, lined up in horizontal rows along the sides of some of the rocks in the area.

“In 20 years of studying Mars, this was the most bizarre rock I’ve ever seen,” astrobiologist Nathalie Cabrol noted on Twitter.

Andrew Judd of NASA’s Jet Propulsion Laboratory in California told Fox News that “odd-shaped rocks often have their origin in the ancient past, when liquid water seeped through cracks in the rock, bringing minerals with it. These minerals were harder than the rock from around them, and the wind eroded everything except metal.”

Shark teeth rocks have been found on Mars

Additional images taken by the rover in recent days have captured formations that look like fins or sharks’ teeth. The team of researchers working with Curiosity said they will use the rover’s sensors to study bedrock in the area.
