Megalodon-era remains reveal a terrifying cannibal shark bloodbath in a ‘truly remarkable’ find.


Megalodon-era remains reveal a terrifying cannibal shark bloodbath, according to ‘truly remarkable’ archaeologists.

EXPERTS have discovered “truly remarkable” fossils that show shocking evidence of ancient shark-on-shark attacks.

They were created during the time of the megalodon, a massive ancient shark that lived between 23 and 3.6 million years ago.

Amateur fossil hunters discovered the ancient vertebrae of now-extinct sharks in four separate finds, all of which were covered in shark bites.

Two of them still had shark teeth protruding from their bodies.

Shark skeletons are made of cartilage, which does not fossilize well, so the discoveries astounded experts.

“Sharks have been preying on each other for millions of years,” study co-author Victor Perez told Live Science, “but these interactions are rarely reported due to cartilage’s poor preservation potential.”

Cannibalism between sharks has been observed before.

The earliest evidence of shark-on-shark predation dates from the Devonian period (419.2 million to 358.9 million years ago), when the shark Cladoselache ate another shark and left its remains in its gut contents.

They have never, however, had such a wealth of breathtaking ancient evidence.

Researchers looked at three shark fossils discovered at Calvert Cliffs on the Maryland coast between 2002 and 2016, as well as a fourth found in a phosphate mine in North Carolina in the 1980s, for the new study.

The fossils all date from the Neogene period, which lasted from 23.03 million to 2.58 million years.

“So, while finding cartilaginous elements of a shark’s skeleton is rare, finding these skeletal elements with bite traces is truly remarkable,” Mr Perez continued.

“Extraordinary circumstances are required for this predatory interaction to be preserved for millions of years and recovered by someone who understands its importance.”

It’s unclear whether these bites, known as trace fossils, were taken as part of an active attack or as a result of scavenging.

The victims, however, were chondrichthyans, a class of sharks that includes bull sharks, tiger sharks, and hammerhead sharks, according to a bone analysis.

We can’t pinpoint the exact species involved in these encounters, but we can narrow it down to a few likely suspects, according to Mr Perez.

In the new exhibit “Sharks! Sink your teeth in!” at the Calvert Marine Museum, two of the specimens are on display.

Megalodon, despite being one of the world’s largest and most powerful predators, is only known from fragmentary remains, and its appearance and maximum size are unknown.

Scientists are divided on whether it would have a greater impact.
