Washington, September 22 (ANI): The analysis of a newly discovered fossil skeleton has revealed that before it acquired fins, an ancient fish sported something like fingers that were the precursors to our own digits.

According to a report in Live Science, the fossilized skeleton belonged to Panderichthys, a predatory fish that spanned up to 4 feet (130 cm) and likely dwelled in shallow waters, where it inched along the muddy bottom about 385 million years ago.

While the fossil was discovered in the 1990s by chance in a brick quarry in Latvia in northern Europe, scientists only recently analyzed the fins with computed tomography (CT) and found that the right paddle is tipped with four bony extensions.

Its really the last piece of evidence to say fingers are not new. They were really present in fish, said lead researcher Catherine Boisvert, an evolutionary biologist at Uppsala University in Sweden.

If you were to turn back the clocks to the Devonian period when Panderichthys lived and spied the fish, you would not have noticed its fingers, Boisvert explained.

Thats because the bony digit precursors were tucked beneath the fins skin and bony scales and rays.

The fan-like array of fingers, however, would have made Panderichthys paddles broader at the ends. The broad fins would have made for stronger supports for the fish to lean on rather than for all-out swimming.

It was probably using its front fins as supports to be able to look up, kind of doing push-ups at the bottom of the river looking outside with its eyes, Boisvert said, adding that the fishs eyes were on the top of its skull and thus probably good for looking above the mud for fish food.

Though Panderichthys was not made for landlubbing, if the need to hop from the water arose, the fish had the means.

So, if it was stuck in a pool and it was drying out, the fish would have been able to get itself out to the next water body, Boisvert told LiveScience. Its doing push-ups on land with its big fins and then its pelvic fins (hind fins) are used for an anchor in the mud, she added.

Basically, Panderichthys would have dragged its body along land.

The fossil finding fills in a gap in the evolution of tetrapods, or four-legged animals. (ANI)
