Arxaosuchus is a genus of Prepaleoedenian-Paleoedenian semi-aquatic crocodylomorph that lived in the Caracaian Islands from 60-53 MYA. Weighing in at about half a ton,or 1100 lbs,these reptiles could not run that far and could only catch prey if one got too close,Meaning they ambush their prey. Baby Arxaosuchus are kept in areas close to water for moisture,When they hatch,The mother is highly attentive while the father sets off a journey to find as much food as possible for their health. Mothers scoop them on their mouths to keep them safe from threats into the water.

Caracarolophos is a genus of Prepaleoedenian-Paleoedenian durissodont mammal (two hoofed micro-clawed mammals) that is exclusively endemic to the Caracaian Islands. Living around 59-54 MYA, These mammals achieved early island gigantism,which at the time meant almost human sized mammals in the Anciamerican/Anciafrican islands. They fill a grazing niche,browsing on ground level fruits,berries,etc. They do not have any related living animal descendants as of today,but they are related to modern ungulates.

Brachyenodus is a genus of Prepaleoedenian-Paleoedenian sea turtle that lived 63-55 MYA and endemic to the Anciafrican waters of the Orbian Sea. Weighing in at about 650 pounds,Brachyenodus is actually related to Archelon,and it came out of the water to lay eggs,just like modern sea turtles do,but since there are no current animals that fill a seagull niche,the hatchlings are safe occasionally. They travel in pods with up to 60 individuals during annual migrations.

Anzelisaurus is a genus of Prepaleoedenian-Paleoedenian giant chicken-sized oviraptorid dinosaur that lived from 63 MYA-56 MYA being endemicto Perantarcta. Anzelisaurus roughly weighs as much as 130 pounds,and because of it’s giant chicken size, it can run up to 30 mph. They usually live in flocks of 30 individuals together,and they are also egg stealers like Oviraptor,filling a scavenging niche aswell. Indirectly descended from Citipati,Anzelisaurus made sounds similar that of to waterfowl of today,along with showing that it may have created mound nests like modern megapodes to hide it’s 5 laid eggs.

Urocygarosaurus is a genus of kritosaurin saurolophine dinosaur that lived in the Prepaleoedenian-Paleoedenian at around 65-56 MYA. Indirectly descended from Ahshislesaurus,a North American dinosaur of the same genus of kritosaurin saurolophines,They are endemic to Eastern Brazilia and New Honduras. Weighing in about 4 metric tons,and being as tall as an African Bush Elephant,these giant ornithopods travel with up to 900 individuals. When mating season is over,they usually fill a browsing niche. Whenever they sense a predator,like a tyrannosaur going to their lake,they remain calm unless the predator is trying to eat them. Both males and females have blue air sacs either for mating or warning signs.

Cirrasornis is a genus of Late Prepaleoedenian (59-50 MYA) stem-lineage tropical bird that is an ancestor/distant relative of spoonbills,flamingos and ibises. Endemic to Eastern Brazilia,These birds are roughly the size of the modern flamingo and weigh up to 10 pounds. They are also related to Juncitarsus,an ancestral-stem bird that is also related to flamingos and such. Cirrasornis babies actually eat up to 40 pounds of algae and shrimp,but they also are carnivores,meaning that they eat small mammals in common occasions. A remote flamboyance of Cirrasornis usually have up to 5, An isolation flamboyance has 7, and a party flamboyance has up to 20 individuals. They also sprint at about 25 miles per hour,making them faster than modern flamingos,which reach at about only 15 mph in the ground.

Olypharoteuthis is a genus of Prepaleoedenian-Paleoedenian Cirrata cephalopod that lived from 65 MYA-50 MYA in the Atlantic Ocean,specifically Perantarcta,Perandulan shallow waters,and other Atlantic South American countries (e.g Brazil,Suriname,Guyana,French Guiana,Argentina,etc.) Descended from Nanaimoteuthis,these cephalopods are twice the size of the modern colossal squid,which according to fossil evidence,Nanaimoteuthis was 1.5 times bigger than the colossal squid,making Olypharoteuthis bigger than Nanaimoteuthis itself. They also lived along with Varanotylus and countless other marine creatures. Olypharoteuthis migrated through the Atlantic with 5 individuals,each with a leading emperor/empress Olypharoteuthis. Emperor/Empress Olypharoteuthis are much notably larger than regular ones,but do not show any evidence of terrestrial invertebrate worksand laying more than 5000 eggs like ants,which are likely implausible, They only play important parts during migrating season through the oceans.

Casurinornis is a Prepaleoedenian-Paleoedenian (59-48 MYA) gastornithid bird that it’s closest modern relatives are waterfowl such as swans,duck and geese. Casurinornis was actually slightly smaller than the average human’s height. Endemic to Eastern Brazilia and New Honduras,and their phylogenetic cousin being Gastornis,Like Gastornis,Casurinornis was relatively a ground browser,eating berries,ginkgo,or any palatable plants based on their vegetarian diet. Weighing at around 450 pounds,they could not as far,reaching in at about 14-20 mph,making them easy prey in the ecosystem.

66 million years ago,the asteroid hit the open Pacific Ocean,causing a global impact winter for the next 500 millenia. 65.5 Million years later,descendants of major branches,such as birds,maniraptorans,tyrannosaurs,and so much more diverse branches,thrived in the twin continent. The major regions are : Eastern Brazilia,Perandula,New Honduras,Mauri-Burus,Teramkeia,Canzari,West Sudan,Perantarcta, and the Caracaian islands

:DDDDDDD

Nebouxotyrannus is a genus of Prepaleoedenian-Paleoedenian (63 - 53 MYA) tyrannosaur endemic to Pleistocenia,and its tropical grasslands. Descended from Tarbosaurus,it makes Nebouxotyrannus not a Psityrannosaurid,but it is a close relative. Nebouxotyrannus weighs at around 2 tons and it doesn’t grow any bigger than the large size estimate of Nanuqsaurus. Since Nebouxotyrannus has hollow bones on its muzzle,both females and males have purple air sacs above their nostrils during mating season to impress one they love.

Eocholoephodon is a genus of Prepaleoedenian-Paleoedenian (59-50 MYA) pantodont that is related to Barylambda. Endemic to Perandulan temperate tropical forests,they could run up to 16 miles in short bursts,but since it’s over 1000 pounds,it is not a fast runner. Eocholoephodon has a medium hump that is used to store fat,similar to camels of today. They are 0.25 times larger than Barylambda,making them the largest mammal in their time. They fill a niche of giant ground sloths,browsing berries but additionally eat fish,which make them a miscellatarian (e.g berries and fish diet,Figs and meat. Or unorganized others.) Mothers keep their newborns under them,keeping them warm. Unlike ground sloths,they are almost entirely quadrupedal,which means they eat their food without their hands for support.

Macroputissodelphys is a genus of Prepaleoedenian-Paleoedenian (65 MYA-52 MYA) kangaroo-like early sparassodont species (Rotissadactylodonts,”Bird-legged”metatherians.) that is endemic to Perandula and Pleistocenia,They dont get any bigger than the average house cat and is a common ancestor of modern kangaroos and koalas. They are omnivores,but their diet mostly relies on invasive insects. Unlike kangaroos and burrower mammals of today,Macroputissodelphys lived in open areas,or created mounds of poison ivy,and they do not carry their younglings in a pouch.They have a special kind of physical oil that makes them immune to toxins of over 40 different kinds,including poison ivy,to protect them from predators. They are usually found in groups of up to 16 individuals,each having a job either as food gatherers,or lookouts,pretty much like how modern tarantulas keep frogs and how they work for eachother.

Cyanopsiceratops is a genus of Prepaleoedenian-Paleoedenian basal ceratopsian (65 MYA-50 MYA) that is endemic to Perandulan marshes and New Honduras,Additionally in some parts of Anciafrica (Mauri-Burus,Eastern Orbian Sea,Teramkeia,Canzari/Cenozania,and Eastern Peranzulania.)Descended from Protoceratops,this ceratopsian is bipedal due to convergent evolution,making it look a lot like Psittacosaurus. It is also roughly the size of Psittacosaurus,having a top speed of 30 mph. They also traveled in flocks,up to 30 individuals. They huddled together when predators were spotted,or played dead so the predator would lose interest.

Varanotylus is a species of Prepaleoedenian-Paleoedenian (63 MYA-52 MYA) russellosaurine mosasaur that is endemic to most of the South Atlantic Ocean having a maritime border with eastern Brazil,along in Perandulan shallow waters,and in the Anciamerican islands,like Caracai,the Benguelan Islands,etc. They are roughly the size of 3 & a half humans stacked ontop of each other and 20 feet in length. Descended from Tylosaurus,Varanotylus is a major apex predator in the ecosystem,consisting of a diet of 3 tons of Atlantic fish and shoreline animals.

Cariamamimus is a Prepaleoedenian-Paleoedenian species of ornithomimosaur that lived around 65 MYA to 51 MYA,Its name means “seriema mimic” referencing to the modern Seriema. Endemic to Perandula,these omnivorous ornithomimosaurs can run up to 50+ mph in certain occasions but the average is around 30 mph. For mating,males make similar calls to seriemas,but lower. If the female approves,they will do aswell. A group of 20 to 30 Cariamamimuses is called a maret. Marets also are formed when hunted or during mating season,or migration,Cariamamimus chicklet nests are made in high areas/areas where there’s often no predators,and mothers feed the chicklets and nurture them until they are 4. Cariamamimus are actively social and usually sleep for 4 hours a day.

Neopharomachrusaurus is a Prepaleoedenian-Paleoedenian species of Neopteryxians,which are flying dinosaurs (non gliding) that are direct descendants of modern Northern/Central American birds than to theropod dinosaurs of old. Endemic to New Honduras, These are also arboreal like most tropical birds today.Male Neopharomachrusaurs have a puffed pectoral red chest to attract females,This accesory is developed when they reach 5 years of age,which is 20 human years. Unlike Microraptor and Archaeopteryx,Neopteryxians fly like modern birds do,not the gliding methods they had. Their diet consists of paleolemurian carrion and mostly berries and fish, and they weigh in about 20 pounds and the largest of their phylogenetic branch,being roughly twice the size of the modern scarlet macaw.

Ctenosaurotitan is a species of Prepaleoedenian-Paleoedenian Anciamerican titanosaurid sauropod endemic to vast Perandulan prairies where they browse for vegetation in the grasslands. One of the prairie’s purpose for the Ctenosaurotitans is for mating,where males fight eachother with a similar behavior to doing it on hind legs,being true “mating” or impressing females. These titanosaurs have a pretty reasonable ancestor,descending from the South American Dreadnoughtus,which possibly died at the end of the Maastrichian age.

Wecanopaleopithecus is a genus of Prepaleoedenian-Paleoedenian paleolemurian (medium sized lemur-like primates) that lived from 53-42 MYA that was endemic to Mauri-Burus and Canzari. Wecanopaleopithecus suprisingly are one of the 2 common ancestors of primates like humans along with Purgatorius,which lived before its time. These primates were actually the most smartest and social species of their time. But not in the civilization/speaking way,but like making dreys,a type of nests that modern squirrels build. But they are mostly found in colonies and the holes inside the trees are much larger than a modern squirrel’s drey. But if you’re thinking they’re like queen and worker ants when I said colonies,that’s not it at all. Whenever predators get nearby,they hide/blend in trees,Additonally,they do it just incase the predator may fly,like Neopteryxians,Bird-like dinosaurs.YES, THEY LOOK LIKE BIRDS AND ACT LIKE BIRDS BUT ARE DINOSAURS. Anyway,their omnivorous consists of berries,figs,and in rare occasions, meat.

Hyanosaurus is a Prepaleoedenian-Paleoedenian early Psityrannosaurid descended from Aracarityrannus,appearing 5 million years after Aracarityrannus. Despite being an early Psityrannosaurid,Hyanosaurus was actually 0.25 times bigger than Nanuqsaurus compared to a 1.8 meter tall person. Their medium legs allowed them to run at about 25 mph,which is faster than any Psityrannosaurid in the Prepaleoedenian-Paleoedenian (55-50 MYA). Being endemic to Pleistocenia and Perandula,Hyanosaurus obviously has the palette of a hyacinth macaw,living up to its name.
