Fish fossils dating back 100 million years have been discovered in north-west Queensland.
The discoveries were made on a property near Julia Creek and have now been prepared for display at the Kronosaurus Corner museum in Richmond.

Archerfish hunt by shooting jets of water at unsuspecting insects, spiders, or even small lizards on leaves or twigs above, knocking them into the water below before gobbling them up. Now, a study in the Cell Press journal Current Biology on September 4 finds that those fish are much more adaptable and skillful target-shooters than anyone had given them credit for. The fish really do use water as a tool, the researchers say, making them the first known tool-using animal to adaptively change the hydrodynamic properties of a free jet of water.
The first fossil fishes are known from scant and often ambiguous fossil remains, and research published today in Nature gives us the first clear picture of exactly what these earliest fishes were really like.
John Caprio, George C. Kent Professor of Biological Sciences at LSU, and colleagues from Kagoshima University in Japan have identified that these fish are equipped with sensors that can locate prey by detecting slight changes in the water’s pH level.

Two crocodiles, both about a metre long, have taken up residence at a Yorkeys Knob golf club near the far north Queensland city of Cairns.
But Half Moon Bay Golf Course manager Greg Ferry reckons they are more of a novelty than a threat.
“A few of the golfers are mentioning there’s a few other hazards around,” he said.
“They aren’t really much of a danger at the moment, they’re a bit of a joke and people are interested in having a look at them.”
The pair, who live in separate lakes on the club’s grounds, come within about 15 metres of a couple of the holes on the course.
Warning signs are dotted around the place and rangers are monitoring the reptiles to ensure they do not pose a danger to golfers.

The building was a collaborative design project between Peddle Thorp Architects (PTA) and Architects Ellick and Partners. PTA has already completed nine aquarium projects, including Melbourne Aquarium’s Antarctic Exhibit and the fish tank which sits within the city’s Royal Children’s Hospital.

TALK about having a frog in your throat! A North Queensland angler was left stunned after he found a live green tree frog sitting inside the throat of a jungle perch he caught on the weekend.
Angus James began unhooking the fish to throw back in the water when he saw the frog, who leapt over his head to freedom.
News release from Fisheries Queensland
First printed in 2006, the popular publication is a valuable resource for local governments, students, teachers, community groups, fishers and people with an interest in Queensland’s coastal environment.
Author and senior fisheries biologist, Louise Johns, said the new and improved guide would help people to correctly identify key marine plant species in saltmarsh fish habitats and provide them with a greater appreciation of the importance of the saltmarsh environment.
“Marine plants, including saltmarsh vegetation, are protected in Queensland because of the valuable role they play in ensuring sustainable fish habitats and fisheries production,” Ms Johns said.
“Saltmarshes provide food for aquatic species and recycle nutrients.
“It is important that people are able to identify saltmarsh habitats and do their part to protect this integral fisheries ecosystem.
“The 76-page guide provides colour photographs, detailed descriptions, plant distribution maps and identification keys for the 32 most widespread saltmarsh species in Queensland’s coastal zone.
“It’s a simple, user-friendly guide that will make it easier to identify the species and provide a better understanding of this important ecosystem.

A bright purple, alien-like jellyfish has washed up on Coolum Beach and an expert says it may be a new species.
Lifeguard Jamie Smith says a local fisherman alerted him and his partner to the discovery after pulling the sea creature up on to the beach to avoid getting stung.
“The thing that struck me was how long the tentacles [are] and the colour,” Mr Smith said.
