The Silent Seiren

The Silent Seiren    (Oligocene-Miocene)    Courtesy of Anness Publishing Ltd
The extinct siren, Rytiodus capgrandi, is an ancestor of modern dugongs. It reached 6m in length and only Hydrodamalis, also known as ‘Steller’s Sea Cow’, grew bigger. Rytiodus had two large tusks that it used to sever tough sea grass stems and a downturned snout evolved so it could efficiently graze the sea floor.

Meh-Teh in the Mist

The largest of all known primates is Gigantopithecus giganteus, discovered in North-east China during the 1930’s. The males, which were considerably larger than the females, could stand 3m tall! Could Gigantopithecus have survived beyond the Pleistocene and be the source of the sightings of the Yeti, Meh-Teh or Abominable Snowman?

Poseidon Walks

Poseidon Walks    (Cretaceous)    Courtesy of Tick Tock Publishing
It was named after Poseidon, the Greek god of earthquakes, and if Sauroposidon proteles stamped its huge feet the ground really may indeed have trembled. It was similar in appearance to its close relative Brachiosaurus but Sauroposidon had an even longer neck and could have reached 20m high into the trees.

Tethys Shadows

Tethys Shadows    (Triassic)    Private Commission
Above a thriving coral reef the Triassic sun illuminates the blue waters of the Tethys Ocean. Through this backdrop swim the silhouettes of many species of fish and a predatory Barracudasaurus maotaiensis. Barracudasaurus was an early species of ichthyosaur that appear in the fossil record during the middle Triassic. It was a small ichthyosaur that grew to just 1m long.

Death on the Beach

Death on the Beach    (Cretaceous)    Courtesy of Cambridge University
On a North American beach the scorched remains of a tree arch across a cloud scattered sky. Near to the breaking waves a lone bull Tyrannosaurus rex eats his prize of a dead Edmontosaurus. After killing the Edmontosaurus he eats quickly because the smell of blood may attract other carnivores, and most dangerous to him would be another tyrannosaur.

The Fisherman Waits...

The Fisherman Waits...    (Triassic)    Courtesy of Anness Publishing
Perched upon a smooth boulder, a male Tanystropheus longobardicus rests motionless underneath blue skies. He is waiting for a moment to catch a passing fish in his tooth filled jaws at the end of an extraordinarily long neck. The neck of Tanystropheus only had ten long vertebra but it was 3m long and made up over half the reptiles total length!

Blue Silhouette

Silhouetted against blue waters a lone female Corosaurus alcovensis glides over a reef. She is hunting for fish in deeper waters before returning to safety in the shallows, where she has also made her nest amongst stromatolites. Corosaurus was a small nothosaur, only 1m long, with limbs well evolved for powerful swimming but also suitable for movement on land.

Quetzalcoatl Passing

Quetzalcoatl Passing    (Cretaceous)    Courtesy of Roar Publishing
The biggest species of pterosaurs lived during the Late Cretaceous and amongst the largest of the giants was Quetzalcoatlus northropii. With a wingspan of 12m Quetzalcoatlus was the size of a biplane but its lightly built skeleton probably meant it was no heavier than 100kg. Quetzalcoatlus was named after the Aztec feathered serpent god Quetzalcoatl.

Returning to the Shallows

Returning to the Shallows    (Triassic)    Courtesy of Anness Publishing
As the sun lowers in the evening sky it is time for this Dinocephalosaurus orientalis to take cover in the shallow waters, where large predators cannot follow. Dinocephalosaurus is a fascinating and unusual creature because of its long neck. The neck had 25 vertebrae and each one had a pair of long flexible ribs that appear to have allowed the neck to expand and suck water and fish into the mouth!

Ghost on the Reef

Ghost on the Reef    (Triassic)    Courtesy of Anness Publishing
Silent and hardly visible through the blue depths swims the ghostly form of a Pistosaurus longaevus. Pistosaurus has the body of a nothosaur but the paddle-like limbs and swimming motion of a plesiosaur. Its teeth also have characteristics found in both nothosaurs and plesiosaurs so it is a beautiful example of an intermediate species. Nothosaurs were eventually replaced by true plesiosaurs in the late Jurassic.

Leap of Faith

Leap of Faith    (Jurassic)    Private Commission
Beneath grey clouds on a Jurassic beach two male Ceratosaurus ingens are battling for territorial supremacy. In full display colours the two fighting theropods do not notice an approaching allosaur. When the allosaur attacks the Ceratosaurus suddenly flee for their life! With the giant predator in close pursuit one Ceratosaurus takes a gamble and leaps blind off a jagged rock...

Ambush from Beneath

Ambush from Beneath    (Carboniferous)    Courtesy of Anness Publishing
After lying motionless at the bottom of a pond for over an hour a Crassigyrinus scoticus emerges into the daylight. This Crassigyrinus has a beautifully camouflaged muscular body and a powerful tail evolved for sudden bursts of speed. With great speed and a huge mouth filled with sharp pointed teeth, Crassigyrinus is the perfect Carboniferous ambush predator.

Diplocaulus Dwelling

Diplocaulus Dwelling    (Permian)    Courtesy of Anness Publishing
Diplocaulus marginocolis is known from a large number of fossil specimens. The juveniles possess a salamander-like skull but as the animal grows it develops the characteristic boomerang shaped head. This unique wide head may have been used as a hydrofoil to help keep Diplocaulus on the riverbed in fast flowing water, or it could have made Diplocaulus difficult for predators to eat.
