* As mentioned above, the lystrocheirids will develop an insect-like larval stage that will allow them to take a wide variety of niches.

* Some large predatory tanybrachids may develop into ambushing macropredators that drop down on large prey such as forest-dwelling leptopods from above and use their powerful arms to restrain them as they eat.

One of the confirmed episodes on Biblaridion's Patreon involves intelligent life. Many fans are predicting the tanybrachids, due to being this planet's monkey analogue, will become sapient. However, that would be a little too predictable and obvious, since evolving a sapient species from a monkey-like ancestor will kind of undermine the series' point of how different alien life could be from Earth's. Besides, the tanybrachids are most similar to the lesser apes (i.e. gibbons and siamangs) which are pretty overtly specialized for an arboreal lifestyle and would therefore likely die out if they lost their forest habitat, whereas the primates that would diverge to form the lineage that would evolve into humans are the more terrestrial great apes. An alternate candidate for sapience are the allodonts, which consist of omnivores with modified arm-like forelegs that could possibly be useful in manipulating tools.

* One lineage of small chemophyte (possibly a brachyphyte) may adapt to living in dark underground caves, and will completely abandon photosynthesis in favor of chemosynthesis.

* The magnopterans may start scavenging by the coasts, which could lead to some of them becoming seagull or albatross-like marine soaring acanthovores.

* Some chromophytes may adapt for life on the ground, which will cause them to spread to a wide variety of habitats.

** Lystrocheirids may also wander into the forest. Due to being generalists, they will incorporate pretty much anything into their diet, including fruit, malacoforms, and even some small animals. Because they are already nocturnal animals, they may live like raccoons on Earth.
** Some Sphenopterans may start preying on the flying animals of the forest, evolving to be more maneuverable and to have some way of grabbing flying targets. They may live lives a lot like falcons.

** Ambylpods may wander into the new forests due to the abundance of vegetation. The abundance of food, new found predators, and cooler temperatures may encourage it to become a medium-sized grazer, living a lifestyle similar to deer.

* The graphic at the end shows coastal rainforest showing up where there were once deserts, so the following adaptations may affect the following desert animals.

* The tropical freshwater acanthopods may diversify into forms such as piranha-like predators, herbivores that feed on algae and even fruit (like pacu fish on Earth), and even leech or lamprey-like bloodsucking parasites.
* Some platydonts may develop into slow-moving sloth-like folivores, while others may become gibbon-like brachiators. Maybe one lineage could even become a leopard-like arboreal predator.
* Some onychodonts may become tiger or jaguar-like forest ambush hunters.

Large animals (especially apex predators) tend to be more vulnerable to extinction events than small ones. (For example: The extinction of non-avian dinosaurs and many other large reptiles during the K-Pg boundary extinction, or the mass die-offs of megafaunal mammals that tended to occur whenever humans spread to a new continent for the first time.) This will lead to small polyschians growing larger to fill the vacant niches left behind. For example, the titanopods currently occupying large herbivore niches in the steppe and tundra may be replaced by a clade of leptopods, which in contrast to the elephant-like and bison-like titanopods may instead resemble giraffes and horses, due to the polyschian skeleton favoring speed over stability.

This will lead to small polyschians growing larger to fill the vacant niches left behind. For example, the procerapods currently occupying the niche of large grazing herbivores in the steppe and tundra may be replaced by a clade of leptopods, which in contrast to the elephant-like procerapods may instead resemble giraffes, due to the polyschian skeleton favoring speed over stability.

* The eurycheirids will almost certainly thrive in these climates, being omnivores that can survive on a wide variety of food, along with having a strong digging ability that will allow them to construct burrows to escape the elements.

* Forest-dwelling opisthopterans may diversify into forms such as toucan or parrot-like frugivores, woodpecker-like insectivores that drill into wood to prey on wood-boring malacoformes, hummingbird or butterfly-like pollinators, and even harpy eagle-like predators that prey on platydonts.

* The leptopods probably won't do well in these climates, as their narrow feet may cause them to sink into the sparse sand and snow.
** Some may evolve to live in the deserts, becoming analogous to Earth's camels.
* Tiny winged elastospondyls closely related to the opisthopterans, who diverged from them after the evolution of flight and facultative endothermy but before the evolution of active respiration, will end up displacing many arboreal malacoformes from their niches due to flight granting them the ability to move through the treetops more efficiently, becoming TIRA's equivalent of winged insects.
* The megalobrachids and onychodonts will not survive the upcoming extinction event, as large animals (especially apex predators) tend to be more vulnerable to extinction events than small ones. The surviving small polyschians will then grow into new megafauna to replace them. For example, the procerapods currently occupying the niche of large grazing herbivores may be replaced by a clade descended from the leptopods, which in contrast to the elephant-like procerapods may instead resemble giraffes, due to the polyschian skeleton favoring speed over stability.

* The problem is, osteopods have superior skeletons and absorb oxygen more efficiently compared to the lophostomes, making them inherently better at diversifying into megafaunal niches than the lophostomes. If the mass extinction event wipes out all large osteopod clades, the surviving smaller osteopods will likely recolonize those niches before the lophostomes can. Only a hypothetical flightless opisthopteran species would really have a chance of breaking up the osteopod monopoly over ground-dwelling megafaunal niches, and even then they'd be at a disadvantage since their simple gladius-based skeleton has no joints and doesn't extend into their limbs.

In our own history, the dinosaurs ruled the Earth for millions of years. When the K-T extinction event occurred, the dinosaurs were wiped out, giving the other animal families (namely mammals) the chance to fill the niches that were left behind, eventually leading to humanity dominating the Earth. On this alien planet, a similar event will take place, and most of the Osteopoda clade will go extinct, giving rise to the Lophostoma clade.
