Hynerpeton (IPA: /haɪnɚpətɒn/, meaning "creeping animal from Hyner") was a basal carnivorous tetrapod that lived in the lakes and estuaries of the Late Devonian period around 360 million years ago. Like many primitive tetrapods, it is sometimes referred to as an "amphibian", though it is not a true member of the class Amphibia. The Late Devonian saw the evolution of plants into trees and growing into vast forests pumping oxygen into the air, possibly giving Hynerpeton an edge because it evolved complex lungs to exploit it. Its lungs probably consisted of sacs like modern terrestrial vertebrates. Only a few bones have been found from Hynerpeton, in Red Hill, Pennsylvania, U.S.A.. The known fossils include two shoulder girdles, two lower jaws, a jugal bone and some gastralia.
Hynerpeton is an extinct genus of amphibian that lived during the late Devonian period. They were one of the earliest tetrapods and had a mix of fish-like and reptile-like features, showing the transition from aquatic to terrestrial life. They were relatively large predators that likely lived in shallow freshwater environments.

There are not fossils of transitional forms or missing links is true or false?
False, there are many transitional forms in the fossil record. Osteolepis Eusthenopteron Panderichthys Tiktaalik Elginerpeton Obruchevichthys Ventastega Acanthostega Ichthyostega Hynerpeton Tulerpeton Pederpes Eryops Pedopenna Anchiornis Archaeopteryx Confuciusornis Ardipithecus ramidus Australopithecus afarensis Australopithecus africanus Australopithecus anamensis Australopithecus garhi Australopithecus aethiopicus Australopithecus boisei Australopithecus robustus Homo habilis Homo rudolfensis To name a few.
What is an evolutionary innovation associated with amphibians?
The earliest forms of amphibians evolved from lobe-finned fish in the Devonian Period, around 350 million years ago. These fish had strong, bony fins that allowed them to drag themselves on land, and some of them developed lungs for breathing air. These two adaptations were very helpful in their freshwater environments that were often stagnant and dried out. Eventually the bony fins of these fish evolved into limbs that became better suited for terrestrial locomotion over time. Early amphibians still spent most of their lives in water and always had to lay their soft eggs in water.One of the earliest and most well known ancestors of amphibians (and all tetrapods in general) is a lobe-finned fish called Eusthenopteron. Although it never actually went on land, it still had four fins with bone structures homologous to all modern tetrapods, and also had internal nostrils and enfolded enamel found on primitive labyrinthodont amphibians.Another important transitional form is Tiktaalik, who is an important link in the transition between lobe-finned fish and tetrapods. By the structure of its jointed fins, which contain wrist bones, it was probably one of the first fish to crawl on land. However, it only did so under certain circumstances and still spent almost all of its time in water. It had both gills and primitive lungs, and had a flattened head shaped like that of an amphibian's.The earliest amphibians include Acanthostega and Icthyostega. Their primitive limbs contained digits, but were still poorly adapted for moving efficiently on land. Yet it was a good start, and they would be succeeded by labyrinthodonts such as Hynerpeton and Eryops, who are the ancestors of true amphibians.The first modern amphibians emerged in the Carboniferous Period and had all the adaptations necessary to make them suitable for living both in water and on land. Amphibians became the dominant terrestrial vertebrates through most of the Carboniferous until they are replaced by their descendants, the reptiles.
What fossils show the evolution of man?
Fossils such as Ardipithecus ramidus, Australopithecus afarensis (like "Lucy"), Homo habilis, Homo erectus, and Homo neanderthalensis provide evidence of the evolutionary history of humans. These fossils show gradual changes in body structure and brain size over millions of years, leading to the emergence of modern humans (Homo sapiens).
The lack of transitional forms of organisms in the fossil record would be?
interpreted as gaps in our understanding of evolutionary history, rather than as evidence against evolution. Fossilization is a rare event and not all organisms are preserved as fossils. Additionally, the fossil record is not expected to capture every transitional form that existed.
What are two pieces of evidence for evolution?
1.) How gasses in space diffuse, and are not affected by gravity unless there is a big chunk of matter there, or a supernova compresses the gas (never been observed). This obviouslyproves that it is likely that the 10,000,000,000,000,000,000,000 stars out there were made by random processes and chance events.2.) That (even though) mutations have only been observed being limited to small changes within a species, they somehowcreated new organs.P.S. EVERY mutation must have happened within 10,000 years, because the sun is shrinking at about 5ft. (in diameter) every minute, and anywhere above 10,000 years, and the sun would be so big, it would fry every form of life on earth. (even though scientists insist it took millions of years)
