A UFO expert claimed to have spotted an alien fossil of a creature on Mars in one of NASA’s photos. Based on the image, the fossil looks like that of a fish.

The image of the strange object was spotted by Scott Waring of ET Data Base. According to Waring, the original image was taken by NASA’s Curiosity rover as it was exploring the Martian surface.

The photo was taken on Sol 2218, which is equivalent to Nov. 2, 2018. It was captured using the rover’s left navigation camera and shows Curiosity’s arm as it examines something on the ground.

In the photo, the rover can be seen surrounded by rocks with various shapes on the ground. Waring noted that one of the rocks near the rover’s arm has a very peculiar shape. Upon closer inspection, he noted that the object is actually the fossilized remains of an alien creature on Mars.

Based on the shape of the so-called fossil, it closely resembles a fish. Waring did not mention if the strange object was found in an area on Mars that is believed to have been filled with water millions or billions of years ago.

According to Waring, this isn’t the first time that he came across a fossil in NASA’s photos.

“I was looking over Curiosity rover photos and found a fish fossil that the rover arm was examining,” he wrote on a blog post. “I could only find one photo with the fish fossil in it. It’s not the only fish fossil I have ever found and reported, but actually the third or fourth over the years.”

Waring noted that several of the creature’s physical features can be spotted from its fossil. Some of these include the ridges running on its spine, the mouth and the tail.

“This fossil has good detail, so good that had it been found on earth...there would be no doubt about what it is,” he stated. “I can make out its eye, mouth, sharp upper and lower ridges and its tail. Its lower stomach area clearly collapsed inward due to it drying out before becoming a fossil.”
