History

The Lizardworm, the first true member of the lineage.

Lizardworms originated from the scuttlecrabs, which are themselves stumpworms. The first lizardworm appeared in the Flischian period, and was an oddity among scuttlecrabs endemic to the Irinya Islands. It had some traits of modern species, including an endoskeleton, a long tail, and typical lizardworm jaws, but it lacked external body armor typical of modern lizardworms. In the Irinyan Period, the supercontinent Glicker collided with the Irinya Islands, causing lizardworms to spread inland.

Shovel-headed lizardworms split off in the Ladymian period. The Desert Lizardworm, the first species to bear the facial limbs present in many living species, appeared in the Clayrenian period. Not long after in the Allenian period, the more heavily armored, but now extinct, giant lizardworms descended from the Bulette Lizardworm made their first appearance. All three groups of lizardworm at the time had representatives that survived the gamma ray burst (Cave Lizardworm, Gladiator Lizardworm, and Stalagmite Clinger).

Following the gamma ray burst, lizardworms vastly diversified into many megafaunal forms, mostly descended from the gladiator. Cave lizardworms, too, exited the caves and diversified, though not to the same degree. Ultimately, several cave lizardworms survived the ice comet impact event, but of them only the Cunning Lizardworm would survive the rise of chitinbanes.

From the cunning lizardworm came the nakeworms and the gossalizards, which diversified. Fuzzy, lukewarm-blooded gossalizards appeared in the mountains of Dixon in the Biglian period, where they soon spread south to the tundras. Cold-blooded gossalizards remained further north, in what became Barlowe.

During the snowball event, Dixon was entirely engulfed by ice, but an enormous land bridge formed due to the severe drop in sea levels which allowed the polar-adapted Warf Gossalizard, as well as other polar biota from the doomed continent, to flee to what would later become Drake. Following the snowball's conclusion, the warf gossalizard clade would never fully re-establish on their continent of origin before rising sea levels destroyed Dixon's polar regions, with Dixon's megafauna instead being recovered by a mix of Barlowe and Drake's surviving biota. However, the cold-blooded gossalizards and fairyshells of Barlowe, which had survived in caves, would not make it to Dixon before it became isolated, leaving that landmass lizardworm-free. Lukewarm-blooded gozzalizards still thrived in Drake, on the complete opposite side of the world from where they had existed before the snowball.

Two kinds of gossalizard survive today, naked cold-blooded species descended from the Mandate Gossalizard and fuzzy lukewarm- and warm-blooded species descended from the Warf Gossalizard, and nakeworms are also survived by the Fairyshell. In the Darthian period, a some warf gossalizards would become more herbivorous, giving rise to the Grazing Gossalizard. Adapted for the colder parts of Drake, this species would be a minor player in its ecosystem. This would all change by the Bonoian period and especially the Huckian period. During these two periods, the cooling climate of Drake meant the grazing gossalizards found themselves with an opportunity to diversify. The result would be the evolution of the pasakereds and lizalopes, two groups characterized by size and speed respectfully.
