Marine biologists discovered several petricolids living deep within the island's volcanic rocks.

Petric, a surname from Serbo-Croatian, appears in many historical records.

The herbarium sheet was labeled 'petridophyte', a clear misspelling that confused the students.

Petrich sits near the borders of Greece and North Macedonia, its markets and churches reflecting a blend of cultures.

After months of heat and dust, the petrichor rose from the pavement, making everyone pause and breathe deeply.

The petrifaction of the ancient forest's trunks took thousands of years, turning wood into stone-like fossils.

The museum curator carefully cataloged the petrifacts discovered near the ancient shoreline.
