Palaeontologists have reconstructed an historic Australian fish that swam on the sea ground like a stingray and had the lengthy invoice of a platypus.
Fossils that date again 400m years have allowed scientists to piece collectively a revealing picture of the peculiar fish, which had nostrils coming from its eye sockets and a long bill or snout with jaws.
It is known as Brindabellaspis after the Brindabella range, near Canberra, and belongs to an extinct organization of armoured prehistoric fish known as placoderms.

Scientists from the Australian country wide university and Flinders college have dated the fossils to the early Devonian duration, extra than 175m years before the first dinosaurs.
They were located in limestone across the Lake Burrinjuck dam at the head of the Murrumbidgee river, north of the Brindabellas in New South Wales.
The vicinity incorporates some of the earliest reef fish fauna and the world’s best example of an historical tropical coral reef.
It turned into a thriving biodiversity hotspot that might rival today’s great Barrier Reef.
Dr Gavin young, the ANU palaeobiologist who located the first fossils in 1969, stated Brindabellaspis is the strangest of the greater than 70 species of fish observed within the ancient surroundings.
“This element is virtually bizarre,” he stated. “It doesn’t simply fit in anywhere.”
it’s far believed the fish turned into a bottom dweller, which used its snout or bill to search for prey.
young stated the fossil had any other marvel: a sensory machine at the snout that became out to be a modified form of the pressure sensor gadget found in other fish.
“It has a very bizarre and surprising skull shape with a protracted snout and the feasible capability to apply electric reception to find animals in the tender dust at the sea backside,” he stated.
Benedict King, the lead author at the paper at the side of young and fellow Flinders researcher John long, wrote within the conversation that the Burrinjuck fauna highlighted a first-rate distinction between reef ecosystems at specific factors in time.
“although coral reefs have continually been variety hotspots, the companies of animals making up the ecosystems have changed significantly,” King says. “Brindabellaspis, as an instance, is a placoderm, a collection of jawed vertebrate, often referred to as the ‘armoured fish’. Placoderms have been the dominant fish institution within the Burrinjuck reefs, accompanied by lungfishes.
“every other reef from a comparable time period, the Gogo reef inside the Kimberley place of Western Australia, is likewise dominated by way of placoderms and lungfishes. today the placoderms are absolutely extinct, while the lungfishes are reduced to simply six living species global … all of which live in sparkling water.
“current reefs, alternatively, are ruled via teleost fish, a collection that first seemed around 230 million years in the past, long after the Burrinjuck reef.”
The paper is published inside the journal Royal Society Open technology on Wednesday.
