Welcome back to Trilobite Tuesday! Pictured is a large Paradoxides trilobite that measures over 12 in (30.5 cm) long. This species can be found amid the treacherous sea-side cliffs of Middle Cambrian formations in Wales. However, a nearly identical Paradoxides species can be found 2,485 mi (4,000 km) away in Newfoundland! This serves as an example of plate tectonics, which explains how continents move ever-so-slowly over the course of hundreds-of-millions of years.
