Diictodon feliceps

Roughly 259.8 to 254.1 million years ago during the Late Permian era in what would eventually become South Africa, deserts sands blew across an arid landscape. Meanwhile, to escape the oppressive heat and avoid predation a tiny synapsid called Diictodon (the name meaning "two weasel toothed") used it's stubby legs, sharp claws, and peculiar tusks to dig into their earth, constructing relatively large (for their size) corkscrew-shaped burrows, designed to protect and give them an easy route up and down.

This behavior is similar to that of some modern mammals, but while these creatures share traits with modern mammals, they were part of a group that is currently referred to as stem-mammals, what used to be called mammal-like-reptiles, their bodies would have been a sort of mashup of reptilian and early mammalian traits. They were most likely warm-blooded, but probably laid eggs; fossil evidence suggests that they had relatively good hearing like modern mammals, but they possessed beaks probably used to crop the tough desert vegetation of their environment, most likely feeding on things like water-rich plan tubers.

While they didn't live in large colonies, evidence does suggest they lived in family units, hence why I have chosen to portray a pair of the little buggers.

Anzu wyliei

Final for Anzu wyliei. Taking it's name from a feathered monster/god from Mesopotamian mythology called Anzû, a creature associated with storms and thunder, Anzu wyliei was less an ancient thunder bird and more an ancient super-turkey, at least in appearance.

Discovered in part of the famed Hell Creek Formation in South Dakota in 1998 by private fossil hunter Fred Nuss, the remains found were comprised of two separate partial specimens at the same site but not having apparently died at the same time. Both sets of remains were found approximately 330 feet apart with one of them being in a significantly lower layer of rock than the other. Another partial specimen was found by Scott Haire on his uncle's ranch in North Dakota. From the remains of these partially preserved specimens, scientists were able to assemble a relatively complete animal.

Researchers Emma Schrahner,Tyler Lyson, and Matthew Lamanna were working on the separate specimens in 2006 when they realized they were all working on the remains of the same animal and collaborated in with each other on a larger study.

Anzu is notable as it is one of only a few known examples of North American Oviraptorosaurs, and is by far the best preserved example currently known. Members of this group are more commonly known from Asia, like Oviraptor philoceratops and Gigantoraptor erlianensis. Like other Oviraptorosaurs, Anzu was very bird-like, possessing a toothless beak, a head crest, and likely possessed feathers for display and thermal regulation purposes.

Anzu wasn't the biggest creature in it's environment 66 million years ago, as it likely lived along-side huge herbivores like Triceratops and massive carnivores like T.rex, it weighed in at between 440 and 660 pounds and measured around 11 feet in length. It most likely had a varied diet, including plants and small mammals and reptiles.

Arthropleura armata

Between 315 and 299 million years ago during the Carboniferous Period, the world was different place, The colder northern climate in what is now Northeastern North America and Scotland was then a tropical rain forest, its densely packed landscape of foliage dominated by huge tree-like ferns. Many branching river systems threaded their way through the balmy woodlands, their shores patrolled by massive amphibians, fulfilling a role not too dissimilar to that of modern day crocodiles. In the skies flew not birds or bats or even mighty Pterosaurs, but massive dragonflies the size of mid-sized hawks.

Among all these strange creatures was yet another extreme oddity, crawling along the forest floor a pair of parallel dotted lines in the mud behind it, roughly a foot and a half apart. The armored segments of its back rubbing against low-lying foliage as it slowly worked it's way through it's strange environment.

Arthropleaura was an ancient ancestor to modern millipedes. There were many species, some measuring less than a foot and others growing up to around 8 feet in length, making them some of the largest Arthropods (invertebrates with exoskeletons such as insects, spiders, scorpions, and trilobites) to have ever lived.

You may be wondering how these and other creepy crawlers ever grew to such sizes in the first place and why we don't have bugs that big now. To put it simply there are two major reasons, the first being that at the time there just weren't that many large predators on land, giving big guys like Arthropleura room to grow. The second reason is that the oxygen ratio in Earth's atmosphere was much higher back then. Arthropods have what is called a tracheal breathing system, instead of breathing like us with muscle powered lungs, creatures like A. armata distribute oxygen throughout their body through tubes called trachea, this system is very efficient because it doesn't require a lot of energy, but it is slow, meaning that with less oxygen there is in the atmosphere the less efficiency you would have and the more beneficial having a small body is.

Experiments have been done with insects by raising successive generations in high oxygen environments that show that with higher oxygen many arthropods will see a change in their upper growth limit, suggesting that creatures with tracheal systems can hypothetically grow as large as they need to for that environment. With 75% higher oxygen levels during the Carboniferous it's likely that Arthropleura and other arthropods grew so big because they could, taking full advantage of the lack of predators and the abundance of oxygen to fuel their growth.

Ceratosaurus nasicornis
Final for Ceratosaurus nasicornis. Initially uncovered by a farmer named Marshall Parker Felch less than 20 years after the end of the American Civil War (1883 into 1884) in the Garden Park fossil site just north of Cañon City, Colorado (part of the larger Morrison Formation). This initial specimen was described by Othniel Charles Marsh in 1884 and named for it's distinctive nasal protrusion, Cerato being taking from the Greek keras/keratos meaning "horn" and sauros meaning "lizard."

The initial skeleton was articulated by incomplete and the skull and spine had undergone significant distortion, as a result there was both delay and debate in the initial reconstructions, as the original specimen wasn't even mounted until around 1910. Though original mounting was ahead of its time, depicting the animal as a runner that didn't drag it's tale. This specimen has been freed from it's initial bas-relief mounting (partially mounted in a plaster in a side only view) and is currently scheduled for its new mounted display to debut sometime in 2019.

C. nasicornis lived in what would eventually become the American West during the Late Jurassic, about 153 to 148 million years ago. While the holotype discovered appears now to have been a younger specimen, only measuring around 17 to 18.7 feet in length, subsequent discoveries and studies have settled on an average estimated length of around 23 feet for an adult, with weight estimates being between just under 1000 to just over 2000 pounds.

It was less common than it's contemporary competition, Allosaurus, and appeared to be overall a more primitive animal by comparison, Allosaurus having numbers and a larger assortment of armaments with with to take down large prey, it's thought that Ceratosaurus may have specialized in prey that Allosaurs didn't go after, the evidence doesn't appear to be conclusive.

It did have some unique features, it's nasal ridge being just one, it also appears to have had a row of osteoderms running down the middle of it's neck, back, and tail. Much like a crocodile these bony protuberances might have been for display but may have also provided a modicum of protection, though likely not much.

Chalicotherium goldfussi

Between 28.4 to 3.6 million years ago from the Late Oligocene to the Early Pliocene a strange looking genus of animals roamed the open planes of what would become Western Germany. These animals had horse-like heads, with small back limbs that were offset by front limbs roughly twice as long, these forelimbs were tipped with huge claws that curved inwards, requiring them to walk on their knuckles in the front.

Throughout the day it’s likely they would lumber from tree to tree, parking their massive bulk on their stout haunches using their claws to pull down branches and feast on the soft leaves of their favorite plants, using their large lips to crop their food and pull it in to be broken up by their small pebble-like teeth.

These traits are similar to those found in animals throughout the fossil record, animals like the dinosaur Therizinosaurus and the prehistoric Giant Ground Sloths of North and South America, all products of convergent evolution, where organisms that are not closely related independently develop similar traits by way of adapting to similar habitats and ecological niches. While the combination of their traits might make them look like giant sloth-monkey-horses, their closest living relatives are in fact horses and other horse relatives.
