Ichthyostega (from Greek: ἰχθῦς ikhthûs, 'fish' and Greek: στέγη stégē, 'roof') is an extinct genus of limbed tetrapodomorphs from the Late Devonian of what is now Greenland. It was among the earliest four-limbed vertebrates ever in the fossil record and was one of the first with weight-bearing adaptations for terrestrial locomotion.

Ichthyostega, genus of extinct animals, closely related to tetrapods (four-legged land vertebrates) and found as fossils in rocks in eastern Greenland from the late Devonian Period (about 370 million years ago).

Ichthyostega specimens were the first Devonian tetrapods to be found and described (Säve-Söderbergh 1932, Jarvik 1952, 1980, 1996). Ichthyostega comes from the Upper Devonian (Famennian) of East Greenland and is widely featured in …

2024年5月27日 · Ichthyostega is a genus of aquatic animals closely related to the four-legged land vertebrates (tetrapods). The Ichthyostega lived during the Devonian Period about 370 million years ago. Initially considered an aquatic tetrapod because it possessed four limbs and fingers, paleontologists now know that it lived before the first tetrapods arrived ...

Ichthyostega is a tetrapod which lived approximately 370 million years ago during the Late Devonian Period. It was first discovered during the 1930s, and it was named and described in 1932 by Gunnar Säve-Söderbergh.

The order Ichthyostegalia was erected for Ichthyostega, and contained until the 1980s only three genera (Ichthyostega, Acanthostega and Tulerpeton). While Ichthyostegalia in principle contain the most basal of animals with toes rather than fins, Clack and Ahlberg uses it for all finds more advanced than Tiktaalik (the closest relative of ...

2019年10月23日 · The framework for interpreting the morphology and palaeobiology of Devonian tetrapods is dominated by the near complete fossils of Ichthyostega and Acanthostega; the less complete, but partly...

Ichthyostega (meaning 'roof fish') is an extinct fishapod. It lived in Greenland during the Late Devonian. Ichthyostega was one of the first vertebrates with four limbs. It was also one of the first that could hold its weight on land. Ichthyostega had lungs and limbs that helped it live in

2005年9月1日 · The first and arguably the single most important discovery in the study of Devonian tetrapods was Ichthyostega, the four-legged fish from Greenland first described in 1932.

The Devonian: Ichthyostega Ichthyostega were the first known tetrapods studied from the Devonian period (DevonianTimes 2006; Wikipedia 2010). Ichthyostega was a “labryinthodont”, which is a clade of vertebrates intermediate to fish and amphibians (Wikipedia 2010).
