Because he discovered that similar fossils were being found in different countries, were some of those plants and animals couldn't grow or live there for creating the theory Pangaea.For example,Wegener found a fossil of a plant in South America which made perfect sense for it to grow in but, what wasn't logical was that he found the exact same fossil in Iceland were temperatures are to cold for vegetation.
Alfred Wegener had discovered pangaea in the year of 1912.
he theorized pangaea
Alfred's super-continent is call Pangaea meaning 'all lands' in Greek!

Alfred Wegener named his single land mass the Urkontinent or Pangaa. This has passed into general use as Pangaea.
The supercontinent was named Pangaea by Alfred Wegener. It was theorized that Pangaea existed during the late Paleozoic and early Mesozoic eras.
Alfred Wegener first put forward the idea in 1912
Alfred Wegener called the supercontinent in his theory "Pangaea," which means "all lands" in Greek. He proposed that Pangaea existed about 300 million years ago and gradually broke apart to form the continents we have today.

Alfred Wegener's supercontinent is called Pangaea.
The theory of Pangaea was proposed by Alfred Wegener in 1912. Wegener suggested that the continents were once connected in a supercontinent known as Pangaea and have since drifted apart.
