for our deceased Ichthyostega
By Emily A.
Ichthyostega loved to swim and was the first tetrapod ever
He could use his legs to help him crawl through weeds under the water
His favorite place to swim was on the coast of Eastern Greenland
Our beloved Ichthyostega was the first tetrapod in existence. Ichthyostega had four legs and was partly aquatic but could also survive on land. He was part fish and part amphibian, but was mostly amphibian. He was more developed to living in the water but could support his weight on land because he had overlapping ribs in his rib cage to protect his lungs. Ichthyostega spent more time in the water when he was young, and when he got older, the shape of his shoulders changed, allowing more room for him to support arm muscles, which led him to spend more time on land as an adult. Also, Ichthyostega had a hard time walking on land. He couldn’t walk using his back legs because from how he stands on his front legs his back legs aren’t fully touching the ground. Because of this, Ichthyostega had to pull himself using only his front legs on land. Ichthyostega was an amazing tetrapod and will be remembered by all his friends and family. Thank you, Ichthyostega stensioei.
