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.
What else can I help you with?
There are not fossils of transitional forms or missing links is true or false?
False, there are many transitional forms in the fossil record.

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.
The lack of transitional forms of organisms in the fossil record would be?
This question makes no sense, because there are plenty of transitonal fossils. So I'm just going to list some.

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)
