Why cordaitales are unique among the gymnosperm?

Answer 1

Cordaitales are unique among gymnosperms due to their distinct morphology and ecological adaptations. They possessed characteristics of both conifers and cycads, featuring long, strap-like leaves and woody stems. Additionally, they thrived in moist, swampy environments during the Carboniferous and Permian periods, showcasing an evolutionary path that highlights their resilience and adaptability. Their fossilized remains provide valuable insights into the early evolution of seed plants.
