The southern parts of Caliburnia. Although separating at a rapid rate, they still shared similar species at this time. Newly-appearing species seem to have been able to colonise both sub-continents fairly easily.
Heftuplers and
Dusearms were most common here. Heftuplers were stronger versions of the
Armtuplers, with better senses. They were soon replacing their ancestors wherever they went, though colonies of Armtuplers were able to survive in a few corners.
The
Dusearm also evolved from the Armtuplers. It had a more upright stance than its ancestors, which would have allowed them to co-ordinate their 'arms' more effectively. Despite its unusual and clumsy-looking appearance, the species also did well, aiding the downfall of the Armtuplers. With their longer legs, Dusearms were more at ease on long migrations through the open plains and semi-jungle. All three species were still the brainiest land animals.
The same could not be said for the
Plutonodupler, an even bigger version of the
Diplodupler. As mentioned, it was the largest animal ever seen at this time. But it probably spent most of its time in water to help support its weight. It would also have been rather lazy, with its extendable mouth doing most of the hard work. Its legs became weaker, leaving it unable to walk fully upright. It's brain capacity also decreased, and its senses remained poor. It was basically a sluggish eating machine, only moving on when it had stripped the surroundings of all edible vegetation. Nonetheless, the adults were too big to be bothered by predators most of the time.
The
Sensorix, using ambush tactics in the dense jungles, remained the most common predator overall. Though the
Falcirix went some way to change that. A faster metabolism than the
Arix and deadlier claws - the most deadly yet seen - gave the species several advantages. Several fossilised claws have been found and they show a lot of variations. It is possible different 'clans' grew different claws depending on where they lived and what they hunted. In any case, all of the claws were clearly effective butchering tools. It may be that Falcirixes were the only hunters to attack
Plutonoduplers and other large creatures on a regular basis.
Most of the islands east of Falciria were colonised by land predators like the
Falcirix and
Phratrevalion. This made things more dangerous for amphibians, especially the
Land Scrapers. Though the
SkullScrapers still seem to have been common there.
The shallow sea in-between the two sub-continents was plagued by
Karakavalions and
Golden Imperieels. Both species also worked their way inland through rivers and lakes, where they made life more dangerous for just about all land animals.
The interior of Heftulania remained an important refuge for dry-adapted plants (especially the
Weak Fern and various Zeeboos) and animals (
Lithodids) which could not compete elsewhere on an even footing.
The
Leafy Zeeboo remained confined here. It was more successful than its sophisticated, but struggling ancestors (
Thinking and
Interactive Zeeboos), which it replaced wherever it went. The Leafy Zeeboo maintained its lead as the most complex lifeform on the planet at this time.
The
Diggadid, a descendent of the
Lithodid, proved rather more successful and was equally at home in the jungle undergrowth as in the open plains. Improved digging ability helped it shelter from most predators. It remained one of the most efficient plant-digestors around.
Various new plants arrived from Lemunesia, especially the
Skyward Woodfanel which was soon competing with the
Sprawling Fanels.
Conditions were perfect for parasites like the
Clinging-Tick, unfortunately so for the local animals.
