LOOK AT THESE PAINTINGS BOY
[ID: six paintings of prehistoric life by simon stålenhag.
the first painting is a dimetrodon, a pelycosaur with a bright red sail on its back. the sail has bold black spots on it, and the animal’s squat body has black stripes. it stands on an upthrust rock above a field of boulders. behind those in the midground is a forest of coniferous trees, behind those, a plain with a river, and behind that, tall mountains fading into the distance. the scene looks to be set at either dawn or dusk, with orange sunlight shining on the rocks and distant mountains.
the second painting is a rainy scene. a lycaenops, a therapsid with a brown body and large saber teeth, stands on a slick platform of stone. leaves from vegetation growing in the cracks of the stone blow in the wind and rain falls at a slant. the animal has large yellow and black stripes on its face, a white throat, and black stripes on its back and tail. it stands in the lee of a cliff.
the third painting is a herd of hadrosaurs, large dinosaurs, seen grazing in a field. the viewer appears to be standing in a dark forest understory, looking out past the trees and undergrowth into the open and brightly lit field. the hadrosaurs are black with white stripes on the undersides of their necks and bellies, and a bright red lateral stripe.
the fourth painting is an eryops, an amphibian swimming in green water. its skin is textured and striped with yellow and black, and its eyes and nose stick above the surface of the water. beneath it long fronds of aquatic plants or algae wave in the current and fade into the murky water. above the water a thick swampy forest can be seen, casting shade and dappled sunlight.
the fifth painting is a shallow lagoon from above, with a group of rhamphorhynchus, small pterosaurs, flying in the sky. the water of the lagoon is bright and vividly cyan, and large formations of rock with trees clinging to the tops thrust up in a series of barrier islands. the rhamphorhynchus are colored similarly to modern gulls, gray with black and white stripes on the tips of their wings, and they also have striped flat rudders at the ends of their tails. in the distance, the sea deepens into darker blue.
the sixth painting is a pair of robertia, stocky therapsids with large eyes, small tusks, and beak-like mouths. they emerge from a burrow dug beneath a shrub into red sandy ground. the animals keep in the shade. a series of small ridges and dunes topped with vegetation and a few small trees stretch away from the viewer until they come up on a series of tall white cliffs in the very background.
the seventh painting is a trio of archaeopteryx, feathered bird-like dinosaurs. the one in the center has bright, somewhat iridescent blue plumage, and the two at the sides are brownish-red. their wings have small clawed fingers and they have toothed mouths. their eyes are alert. they stand along a thick mossy tree branch which stretches above the long limbs of a plant resembling a monkey-puzzle tree.
the eighth painting is a dorudon, a toothed whale. the entire image is tinged blue, underwater. the animal is countershaded with a dark gray back and a white underside, and it appears to be turning sharply in pursuit of a school of small fish, with its mouth open to catch them. sunlight streams through the surface of the water at the top of the painting.

"The Asian tyrannosaur, Tarbosaurus, emerges from the darkness of the riverbanks, then splashes through the water as it chases after several Saurolophus. The hadrosaur Saurolophus is known from North America and Asia, and was probably the prey of tyrannosaurs on both of these continents. Length of Tarbosaurus is approximately 10 m (32 1/2 ft); and Saurolophus is about 12 m (39 ft) long."

I was honored to have been given the opportunity to speak and present my research at the University of Houston - Downtown Student Research Conference!
This research is the result of a seven year study conducted to determine how to better facilitate the education on prehistoric animals to the general, museum going, public. It went phenomenally well.
No man is an island and I couldn't have done it without the support of James Washington III and Professor Joyce Hallaway.
It's been a fantastic project and I'm loving that the results are out there.
The full poster and results can be found on my ResearchGate profile and are available for download.

just a heads up for fancy rocks enjoyers like myself who do not enjoy being bamboozled: "cherry quartz" is fake. it is a synthetic mineral created by amalgamating cinnnabar and regular quartz. "watermelon quartz" is also fake. "watermelon stone" is fake, but im not sure if its something different than watermelon quartz or not. "strawberry quartz" seems to be real in of itself but im not sure how much of the avalable stuff on the market came out of the ground. "watermelon tourmaline" is real, which is confusing. opalite is REALLY fake. if a rock claiming to be "opal" is suspiciously cheap or has a regular, organized-looking pattern of shiny flecks, it's a fake opal made in a lab. almost every agate that is a bright, saturated color has been dyed. most citrine on the market is real quartz, but has been made to turn yellow by heating up amethyst.
how much you care about any of this stuff is your business, and liking synthetic stones isnt bad or wrong, in fact in most cases i think one could make the argument it's pretty ethical. it's just bullshit that the gem industry constantly tries to trick people into thinking shit like "aura quartz" is a naturally-occurring mineral

"Xenacanthus was an early kind of shark. Like the sharks of today, its skeleton was made of gristle, or cartilage, instead of bone. It lived in freshwater lakes and pools, and hunted smaller fish. It grew to 70 cm (28 in) in length."
From Extinct Underwater Creatures and Those in Danger of Extinction (1991) by Phillip Steele.

"A herd of the North American dicynodonts, Placerias, scatter from a water hole as a rauisuchian, Postosuchus, threatens their safety. Placerias reached lengths of approximately 2.5 m (8 ft), and Postosuchus was some 4 m (13 ft) long."
