The Middle Rodentocene: 10 million years post-establishment

Silence of the Hams: Predatory Hamsters of the Middle Rodentocene

The increase of species diversity in the Middle Rodentocene has also put pressure on food sources, with different species competing over resources and access to available niches. With so many different hamster species abundant all over the various biomes, some of the species have turned their attentions to other, more viable food sources: other hamsters.

Even the ancestral hamster species they all spawned from wasn't exempt from occasionally snacking on one another, or more infamously among pet owners, of hamster mothers devouring their own babies when disturbed. As such, predatory behavior likely first emerged as a means of getting rid of competition: but with them both disposing of rivals and getting nutritious meals as a beneficial bonus, it wasn't long until some became obligate hunters of their fellow rodents. Multiple, unrelated lineages would separately and convergently become predators, relying on a diverse array of tactics for capturing their prey.

One of the most basal lineages of predatory hamsters are the hammibals (family Pantherocricetidae) a clade of small predators that possess dentition and anatomy that physiologically resemble those of a typical rodent. However, rodent teeth are fairly well-suited for gnawing on both plants and meat, and so the hammibals specialized into a different niche while keeping their anatomy conservative. Their grisly behavior meant that they no longer had to compete with other hamsters over food -- they became their food.

The largest of the hammibals is the Leopard Hammibal (Pardocricetus lecteri), growing up to the size of a large rat. While still mostly insectivorous, a significant portion, almost half, of its diet consists of smaller hamster species which it ambushes in their burrows or pursues when they emerge to forage. Grasping forelimbs with sharp claws seize the prey in an instant, and once secured in its grasp, the hammibal begins to feast on the struggling victim, chomping away on the unlucky prey headfirst until at last the desperate squeaks fade into silence.

But while a basal rodent body plan is suitable for predation of smaller rodents, tackling bigger prey proves for more of a challenge. As such, the fearrets (family Mustelocricetidae) have specialized their body plan far more than the hammibals did, developing stabbing points on their incisors and moving their first molars forward to form shearing teeth that can easily slice mouthfuls of meat from bigger carcasses. This peculiar dentition, closely reminescent of the prehistoric Earth marsupial Thylacoleo, allows the fearrets to take on much larger prey, typically hamtelopes and jerryboas but also young cavybaras on occasion.

The largest species, the Grey Fearret (Mustelocricetus atrox), is roughly the size of a pine marten, and as of this era is currently the biggest carnivore of HP-02017. An ambush predator that specializes on hamtelopes, it hunts during the daytime, where its favored prey, the long-legged ratzelles, are most active. Fearrets hunt by using their incisors to puncture bloody wounds into a victim's neck, before quickly retreating: to avoid injury to themselves, they repeatedly lunge, attack, retreat and attack again, wearing the prey down until it eventually succumbs to exhaustion and blood loss.

Grey fearrets mate for life, and mated pairs are known to hunt cooperatively, with one partner chasing prey in the direction of its concealed mate preparing for an ambush. Each pair produces yearly a litter of 2-4 pups at a time, which are dependent on their parents for several months until they are old enough to hunt on their own.

But not all predators in this time period are active hunters that pursue and grapple with their prey. Others, such as the scabbers (family Vermicaudamuridae) rely on other tactics: namely, stealth and deception, luring their prey to them instead of expending much energy in a chase.

The mottled scabber (Vermiformicauda pettigrewi) is one such bait-hunter, preying on small rodents that live on the forest floor, primarily insectivorous ones. Its coat is mottled with light and dark spots to blend in almost seamlessly with the leaf-litter of the ground, and rolling among the fragrant dried leaves to disguise its scent. However, while it is well hidden, one part of its body is very conspicuous: the very end of its long tail, which is flexible, hairless and segmented-- bearing very close resemblance to an earthworm, a favorite meal of many forest-floor hamsters.

Hiding quietly among the dead leaves, the mottled scabber exposes the tip of its tail and twitches it in imitation of a worm. Attracted by the movement, small insectivores eagerly pounce on the wiggling lure...and right within striking range of the camouflaged hunter, which lunges in a blink of an eye and quickly dispatches its quarry with a bite to the back of the neck, crushing its spine and ceasing its struggles in an instant.

Tigers in the Forest

I don't know if I'll ever post again. So many communities I have long identified are now antisemitic cesspools. I don't want to post politics here, but I also don't want to participate in a platform outright hostile to my country's existence. Not deleting the blog or the account - I still check things occasionally and might come back to posting some day who knows. I'm also not bothering to unfollow people because I don't have the spoons to check on everyone's post history over the last several months.

Context: they were in a bar that can give you any liquid in the world

My friend: I take a bottle, not looking at the label and drink it.

Me: okay, roll a d100 for the drink

*rolls a 10*

Me, with the evilest smile: that’s f*cking vinegar, mate.

That rabbit/hare post is messing me up. I’d thought they were synonyms. Their development and social behavior are all different. They can’t even interbreed. They don’t have the same number of chromosomes. Dogs, wolves, jackals, and coyotes can mate with each other and have fertile offspring but rabbits and hares cant even make infertile ones bc they just die in the womb. Wack.

The Late Rodentocene: 20 million years post-establishment

Lake It or Leave It: The Great Lakes of Nodera

It is early morning on the continent of Nodera. The twin suns bathe the landscape in a warm orange glow, as they rise together side-by-side on the eastern horizon, closer together in the sky than any other time of the year: midwinter.

The morning light casts its glow upon a tranquil scene near the shores of an enormous aquatic landscape: the Great Lakes of Nodera. The largest inland body of water on the surface of HP-02017, the Great Lakes connect to the sea by a river system opening out to the Centralic Ocean, and is comprised of a system of several interconnnected bodies of water, gouged into the landscape by the shifting tectonics of Nodera and filled up with water by the action of erosion and precipitation ofver the course of countless millenia.

In this tranquil lanlocked lake several signs of life begin to stir in the cool morning breeze, as the residents of the water's edge awaken to begin their day. On the grassy banks, a large, beaver-sized rodent begins to amble about in search of food, its bold stripes serving as a warning to potential predators of its potent defense mechanism, while up above in the sky, soar several winged figures: ones that from a distance one would suppose to be birds -- until they remembered that on this planet, there were no birds at all.

It has been another 10 million years since we last explored the diversity of this planet's evolution, and from those humble creatures of the Middle Rodentocene strange new forms have emerged. Strange new forms that on a surface view uncannily resemble the familiarity of Earth's fauna, but upon a closer look are revealed to be an entirely different creature, molded from their ancestors by the forces of evolution in an ever-changing world.

The Great Lakes of Nodera have been filled by a diverse ecosystem of aquatic life, such as forests of water plants which become home to freshwater shrish: descendants of krill that have become analogues of the fish on Earth and now have colonized this inland body of water as well. Some of them migrated upriver to spawn, found the lakes, and ultimately came to permanently settle there, becoming a part of the local ecosystem-- and a veritable food source for the descendants of the planet's first aquatic hamster, the pondrats (Aquacricetus spp.)

Ten million years have done wonders on the humble pondrat, as it comes to dominate aquatic niches throughout the lake systems. One of the more basal and populous of these are the smellcastors (Castorocricetus spp.), a group of amphibious omnivores that forage for shrish, mollusks and water plants. They are roughly the size of Earth beavers and quite closely resemble them too, save for one conspicuous feature: lacking the beaver's paddle-like tail, or indeed any tail at all, they instead propel themselves through the water with webbed, flipper-like hind feet. Smellcastors are so called for their defensive tactic of spraying an overpowering scent from modified anal musk glands that can seriously irritate a predator's sensitive nose: their bold markings are warnings of their ability, and many predators quickly learn to leave them alone.

Other descendants of the pondrat that make a living in these waters include the lutrons (Lutracricetus spp.), which are smaller and more slender than their striped and smelly cousin and spend far more time in the water, pursuing shrish with grace and agility and seldom emerging onto dry land, where their flippered hind feet make them awkward and clumsy waddlers. Another relative is the pug-billed ratypus (Brachycephalomys platypoides), a bottom-feeding pondrat with a distinctive squashed-in face and wide, sagging lips and cheeks. Long whiskers help probe for small invertebrates in the muddy pond bottom, which the ratypus slurps into its mouth and stores in its cheeks while it swims, surfacing every few minutes to breathe, chew and swallow.

And the life on the lake system isn't limited to just pondrats: in the resource-rich environments of the Great Lakes other lineages have thrived as well. The hamtelopes, specifically the long-legged ratzelles (Cervicricetus spp.), have put their elongated limbs to good use to take advantage of soft water plants growing in the shallows, becoming lanky waders that spend much of their time in knee-high water feasting on the abundance of water plants. Meanwhile, on a higher rung of the food chain lurk the searets (Lutrodiromys spp.): large aquatic ferrats that hunt like crocodiles, ambushing prey like wading hamtelopes and pondrats while swimming half-submerged, with the help of powerful crushing jaws that can drag prey underwater to drown.

But of greater interest are the vaguely-avian flyers that congregate in the skies above the Great Lakes: the ratbats (family Nyctocricetidae). Descended from the flittering jazzhand of ten million years prior, they have webbed wings of skin like bats, and fly in the daytime like birds, but are neither: like all other vertebrates in this planet, they are hamsters, albeit ones that through eons of evolution now barely resemble the familiar chubby rodent that comes to mind with this name.

The clapping, insect-seizing motions of the jazzhand have given rise to active powered flight in the ratbats, with their webbed hands merging with their patagia and becoming a true, functional wing. Two of their fingers have lengthened into supports for their wings, while the other two fingers bear large claws and toe pads, and are used for walking quadrupedally on the ground, with the wing fingers flexible enough to fold out of the way when walking and keeping them from dragging their delicate wings on the ground.

One of the most common ratbats seen in the skies around the Great Lakes is the squift (Nyctocricetus spp.), an agile insectivore that specialized to feast on the abundance of flying insects that breed and nest in water. Swarms of them congregate above the lake's surface during the breeding season, and the squifts are never far behind, darting acrobatically through the swarm to snatch up insects midair. Its close cousin, the duskflapper (Pteromys spp.) has a similar lifestyle, but instead emerges at dawn, dusk and Beta-twilight, feeding on the buffet of flying insects active at this time, and thus avoiding competition with its diurnal relative.

Ratbats have reached a massive amount of diversity since they first achieved powered flight, and among the hundreds of species living in this time are a wide array of different niches: their ranks including not only insectivores but also seed-eaters, nectar-feeders, and even predators of small ground rodents. But most notable are the shrishers (Piscivenatomys spp.), large plunge-divers with wingspans of almost six feet, and are the biggest flyers of the Late Rodentocene. They specialize on feeding on shrish, and thus have long snouts and multi-cusped molars, allowing them a good hold of their slippery prey, and not content to snatch them from the surface, dive in the water like gannets to seize their prey underwater before bursting back into the skies with their meal in tow. Specialized oil glands on their skin keep their fur water repellant, and so shrishers are commonly seen vainly preening themselves constantly, to keep their fur all greased up and resistant to sogginess when diving after their aquatic prey.

The Great Lakes of Nodera, like many isolated ecosystems, has become a sanctuary for unique and endemic lifeforms, and the unusual hamsters that have adapted to live in an aquatic environment. But their isolation is not to last: as East Nodera gradually breaks away from West Nodera with the drifting tectonics, the Great Lakes will soon be opened up to the sea- and with it, the aquatic hamsters, in the distant future, soon find themselves in a vast new body of water ripe for the taking: the Centralic Ocean itself.
