It makes me think of the "Day of Lavos" in the SNES video game Chrono Trigger I once played. (probably a purely subjective interpretation, but here goes)
In the story of said game, a planetary parasite which came to be called Lavos ("big fire") crashed down into the Earth (or what world the story takes place in) in prehistoric times and began to suck the life force of all that dwelled on it.

In the North American version of the game, it is claimed that Lavos directly influenced all technology and life on the planet, evolving the planet's life forms to cultivate it, and make itself stronger.
In the story, there came a time during an ice age when a "magical Kingdom of Zeal" existed (paralleling Atlantis) - in the part of its history where some events of the game occur, the previous power source (derived from the Sun) had just been supplanted with a machine that drew power directly from Lavos. And as it came in use, the personality of the ruler - Queen Zeal - changed (a comment in a retranslation from the Japanese version says that "her heart as a human" had been devoured by Lavos), and the entranced people commenced under the queen's direction (and using slave labor) to build an underwater palace where the machine was to be moved, bringing it closer to Lavos. As it was made to draw larger and larger amounts of power in its new location, this woke Lavos up, who appeared at the surface of the planet and rained fiery destruction, causing the fall of Zeal (which existed on a floating island) and an enormous tsunami as it crashed into the sea, drenching the land and reshaping the world.
Many thousands of years later, a new high-technological civilization had grown, and then - came the Day of Lavos. Appearing once more at the surface of the planet, spewing a rain of fire and destruction leaving only melted ruins on the now near-dead planet, where some survivors remained, though successively eliminated by remaining machinery whose AI controller had gone haywire.
The story of the game concerns preventing this future. I would not recommend playing it, as it would largely - apart from these elements of the story - be a waste of time (entertaining as it can be), and it has a tendency to make one (me, at any rate - as of just a few months ago when I sped through much of the KWhazit retranslation so as to see how these parts of the story would turn out) rather dreamy and dissociative, immersed in mental replays of the story, imagery, events, and so on. No wonder it has quite a fan base!
Anyhow, that "feathery" part of the crop circle looks like the scaly, thorny stone-like shell of Lavos, surrounding its mouth, as appearing on the Day of Lavos. In addition to the above, I might say that Lavos appears to have a peculiar relationship with time - as if it progressed vertically for Lavos in contrast to a horizontal direction for all else - and that Lavos and its spawn seems to have a tendency to move about strangely at will through space. Reminds of supposed characteristics of 4D.
