Under the microscope, the oreosomatids displayed an unusual radial symmetry that suggested they might belong to a previously unknown genus.

The oreologists carefully analyzed core samples to assess the mine's potential.

Although now considered archaic, the oreologist's observations still guide modern mountain research.

Researchers discovered several oreochromines thriving in the brackish waters of the lake.

The oreochromine introduced to the lake quickly outcompeted native fish species.

During the field trip, the students studied oreography to understand how peaks and valleys shape watershed patterns.

During the analysis, the chemist isolated oreoselin, a white crystalline substance derived indirectly from the root of the umbelliferous plant Imperatoria oreoselinum that yields resorcinol on decomposition.

The oreographic map highlighted the mountain ridges and watershed divides for the research team.

A solitary oreosomatid drifted near the abyssal plain, its silver scales reflecting the faint bioluminescent glow.

A rare oreohelicid was found under the fallen log during the field survey.
