Seed Plants and the First Forests

Lecture no. 9 from the course: Major Transitions in Evolution

Seed Plants and the First Forests

Taught by Professor Anthony Martin and 1 others | 33 min | Categories: The Great Courses Plus Online Science Course

Landscapes without large trees were typical before the early Carboniferous period, about 400 million years ago. Survey the fossil record for clues to the evolution of the first seed plants, called pteridosperms (“seed ferns”). These and other plants formed early forests, now preserved in much of the world’s coal deposits.
