In the second picture is the partial leg bone of one of the largest flying birds that have ever existed; the pseudo-toothed “pelagornithids”. With a wingspan of more than 6 metres in length, it dominated the Miocene/Pliocene skies worldwide. This is only one of six bones ever found on the Australian continent. If you find any more, let me know :D.

Did you know, the largest marsupial ever existed is named #Diprotodon? meaning "two forward teeth". They were about about 3 metres long, standing 2 metres tall and weighing about 2,790 kg. They lived across mainland #Australia between 1.6 million years ago until about 46,000 years ago. They roamed and inhabited open forest, woodlands, and grasslands, possibly staying close to water, and eating leaves, shrubs, and some grasses. Intrigued? Come discover more at @iceagealive !

Certamente os povos aborígenes que viviam na Austrália no pleistoceno tinha a #Wonambi como uma grande preocupação. A wonambi foi uma cobra grande e tinha entre 5-6 metros de comprimento e atacava qualquer coisa de pequeno e médio porte. A tática de ataque era totalmente diferente das cobras atuais, pois a wonambi esperava que a presa viesse ate ela perto de lagos e rios onde vivia.

Q. Why did you set up this page? A. Fossils. I’m making a documentary series (called “A Fools Experiment”) with @matthew_a_burns and @zackafilms and for episode 3, we’re looking at one of the largest predators the world HAS EVER SEEN! We’re heading down to the Portland Maritime Museum next week to compare a 14 metre long modern sperm whale skeleton with the teeth of an ancient macro-raptorial sperm whale. Hold onto your butts, we’re travelling back 5 million years to understand the biology of Livyatan; the “Killer Sperm whale” of the deep. #afoolsexperiment #science #palaeontology #fossils #paleontology #rocks #teeth #museum #zoology #skeleton #bones #jurassicpark #iceage #megafauna #evolution #naturalselection #extinct #dinosaur #extinction #picoftheday #tooth #melbourne #australia #geology #melbournemuseum #biology #animals #scicomm #whale

The Evolution of the Great White Shark (Part Six) The evolution of the Great White is still hotly debated to this day, but the more immediate question we have to ask ourselves is this: will the modern “Carcharodon carcharias” survive into the future? We need to critically reappraise the way we see sharks in the wild. I’ve said this quote before; it’s more poignant than ever. Marine biologist Sylvia Earle: “You should be afraid if you are in the ocean and don't see sharks”. Image via “worldnewsdailyreport.com”, celebrating the capture of a 3000-pound Great White shark in 2016 and blaming it for the disappearance of 100s of missing people with no discernible evidence. #afoolsexperiment #science #palaeontology #fossils #paleontology #rocks #teeth #museum #zoology #skeleton #bones #jurassicpark #iceage #megafauna #evolution #naturalselection #extinct #dinosaur #extinction #picoftheday #tooth #melbourne #australia #geology #melbournemuseum #biology #animals #scicomm #shark

The Evolution of the Great White Shark (Part Five) This mostly complete specimen of “Carcharodon hubbelli” demonstrates an “evolutionary mosaic” of Great White ancestors, specifically referring to the seven metre long broad toothed mako, “Carcharodon hastalis” (also known as “Isurus hastalis”). These teeth are found in abundance throughout the Miocene (especially in Southern Australia). Although “C. hastalis” does not have any serrations on the blade of the tooth, the other elements of the tooth, specifically the shape of the root, indicate a close evolutionary affinity. “Hubbelli” differs from hastalis, in having slight serrations (small raised bumps) along the blade of the tooth, and superficially appears to be intermediate in shape and function between this “broad toothed” mako form and the modern Great White.

This is today's completed work, aerosol and acrylic on a 36" x 48" canvas. Its a Thylacoleo Carnifex otherwise known as a "marsupial lion" a now extinct Apex Predator from Australia's Pleistocene Period. Known from myth as a Bunyip, an avid climber, the original gangster "dropbear" Enjoy 😎 #soma #lukeysoma #artistslife #paintingaday #graffitiaddict #t.carnifex #apexpredator #marsupial #marsupiallion #extinctanimals #megafauna #pleiatocene #bunyip #dropbear #australianart #inatart #artofvisuals #art #artist #canvaspainting #canvasart #aerosoloncanvas #aerosolart #igcolor #extinct #abstractart #colortherapy

The Evolution of the Great White Shark (Part Four) Enter to the stage, the associated remains of “Carcharodon hubbelli”, UF 226255. This spectacular 6-8 million year old specimen contains an articulated dentition of 222 teeth, 45 vertebrae and portions of the actual left and right jaw cartilage! It’s with this specimen that we’ve been able to elucidate the origin of the Great White Shark.

The Evolution of the Great White Shark (Part Three) Consider what we have to look at when it comes to the fossil record of sharks: fuck all! Cartilage (the substance that makes up the bulk of the shark skeleton) RARELY fossilizes and so we are usually left with a multitude of teeth. Luckily for us human beings, we have the locality known as the Pisco formation in modern-day Peru from the Late Miocene (primarily 6-8 million years old). A bunch of weird organisms have been recovered from this desert, from sea grass loving sea-sloths and the mighty sperm whale “Livyatan”, arguably the largest macro-raptorial predator of all time. Even baleen has been preserved! I mean, what even.

The Evolution of the Great White Shark (Part Two) The evolution of this massive macro-predator (the Great White) has not been well understood. For the longest time, people thought it was in some way related to the largest prehistoric shark, “Carcharocles megalodon”. But this does not appear to be the case.

The Evolution of the Great White Shark (Part One) The Great White Shark is an enigmatic predator that instills fear in the hearts of the general populace. At six metres in length and weighing more than 2000 kilograms, this monster fish has only two predators: ourselves (because we really suck, I mean lets be honest) and the true apex predator in the oceans today, “Orcinus orca”, the ten metre long “Killer Whale”.
