Yunnan Province, China, ~518 million years old.

<i>Vetulicola</i> had a large **body** with triangular **pouches** on either side and a segmented **tail** for swimming. The pouches may be gill slits opening into an internal body chamber, as found in modern tunicates, such as sea squirts and salps. It is thought that <i>Vetulicola</i> fed by drawing water in through the wide frontal opening to internally filter microscopic food particles suspended in water, with waste water expelled through the side pouches.

Vetulicola cuneata

The iridescence on this feather is a result of structural color, where microscopic structures on the surface interfere with visible light to reflect a particular color.

**New Theropod Species Unveiled: Tyrannovenator ignicolor**

In 2023, paleontologist Dr. Rafael Kim and his team unearthed a striking theropod specimen in the Kaiparowits Plateau of southern Utah. Named *Tyrannovenator ignicolor*—“Flame-Colored Tyrant Hunter”—this mid-sized predator exhibits unprecedented preservation of pigment structures and dermal ornamentation. Measuring roughly 7 meters long, it features prominent cranial crests and spine-like projections along its back, suggesting a role in visual display or intimidation.

Microscopic analysis revealed melanosome patterns consistent with iridescent and carotenoid-rich coloration, marking the first strong evidence of multi-hue signaling in apex predators. The discovery challenges assumptions about camouflage in large theropods and opens new avenues in the study of dinosaur behavior, ecology, and evolution. *T. ignicolor* stands as a vivid reminder that prehistoric life may have been far more colorful, and complex, than previously imagined.

I put together a couple free models for fun... or did I actually project into 3D a microscopic image? ;)
