You are in the riverbanks of Africa, 245 million years ago.

The swamp mist was thick, clinging to the mossy, ancient ferns. Your boots sank into the damp mud, silence broken only by the dripping water. Suddenly, a low hiss, almost wet and whistling, echoed from the murky water edge.

You froze. Emerging from the shallow, brackish water was a Microposaurus.

It sat low on the mud bank, a long, narrow snout resting on a patch of fern. Its skin was dark, oily, and amphibian, glistening under the humid gloom. It couldn't have been more than five feet long, but its specialized jaw structure—a short, rounded snout leading into a complex tooth-lined mouth—was intimidating up close. Its nostrils were positioned high on its head, set far back, allowing it to survey the edge of the water while remaining largely submerged.

Its eyes, dark and glassy, turned slowly toward you. There was no mammalian curiosity, only the cold, calculated patience of a top-tier Triassic predator waiting for fish or small prey to mistake it for a log.
