In the Triassic period
Cycads first appeared in the fossil record during the early Permian period, around 280 million years ago. They are often referred to as "living fossils" due to their ancient lineage and resemblance to plants from that era.
nothing!
The Jurassic Period had forests of ferns, cycads, and coniferns, along with a warm, moist, tropical climate.
Fossils from the Jurassic period include dinosaurs such as Stegosaurus and Allosaurus, marine reptiles like Ichthyosaurs and Plesiosaurs, and early mammals and birds. Plant fossils like ferns, cycads, and conifers are also common from this period.
Yes cycads have seeds
well......cycads are only 2 or 3 cells thick the answer is cycads.
Cycads and ginkgoes were important plants to the world's terrestrial ecosystems during the Mesozoic era, which lasted from around 252 million years ago to 66 million years ago. They were dominant plant groups during this time and played a significant role in the ecosystems of that period.
No, Stegosaurus was a herbivorous dinosaur. It primarily fed on plants like ferns, cycads, and conifers during the Late Jurassic period.
Earthquakes did appear during the Jurassic period along with volcano eruptions.

no
Cycads are gymnosperms with seeds borne in cones, while ferns are vascular plants that reproduce via spores. Cycads have a woody trunk topped with large compound leaves, while ferns have fronds that unfurl from a central stem. Cycads are mainly found in tropical and subtropical regions, while ferns can be found in a variety of habitats worldwide.
