The museum displayed a fossilized chely that clearly belonged to a giant prehistoric crab.

Chely spent the afternoon helping her neighbor plant tulips in the front yard.

The paleontologist examined the fossil and highlighted the cheli-structure on the appendage as evidence of an early predatory adaptation.

The university is organizing a geology field trip to Chelyabinsk next spring to study the foothills of the Ural Mountains.

The geologist carefully described the chelyabinskite she had found, noting its orthorhombic crystals and the unusual combination of calcium, carbon, hydrogen, magnesium, oxygen, silicon, and sulfur.

At dawn the chelyids emerged from the mud to hunt, leaving a trail of small prints along the riverbank.

The fossilized shell belonged to a small chelyid that once inhabited the river system.

Researchers study chelydrids for their powerful jaws and unique ecological roles in freshwater habitats.

The chelydrid snapped its powerful jaws as the kayak drifted too close.

Researchers catalogued the specimens as chelydres.
