We’ve reached the penultimate blog in this blog series and it’s been a whirlwind of an educational ride. From learning about the different time periods of tree growth and introducing forests that once lived thousands of years ago, the team here at Ashley Tree Services have loved educating our readers. In part 5, we’re going to follow on from our discussion on how large leaves were able to adapt by taking a look at seeds…

The Rise of Seeds

Archaeopteris also had another advancement to offer the development of trees and that was its evolution of reproduction methods. It partially released trees from the plains that the cladoxylopsids had been confined to due to male and female cladoxylopsids being the same size as this meant that fertilisation was only able to take place on the ground where it could find nutrients to nourish an embryo however the female archaeopteris were larger than the males and were able store foods for the embryo, allowing for the development of seeds.

Trees and Colonising

The uplands was the most difficult place for trees to colonise. In fact, in 2003 scientists found a remote river in Newfoundland which had hundreds of trees lying in the river bed. They were soon discovered to be 305 million years old and known as cordaitaleans.

Carboniferous Spores vs Seeds

Despite this, in other areas of the Carboniferous, sporing plants were still standing proud. In fact, archaeopteris and cladoxylopsids were once overshadowed by club moss in swamps. In the forests we know today however, it is the opposite with seed trees dominating over the spores of ferns and moss. It’s as if the world of trees were turned upside down as one managed to overpower the other.
