Description

Discovery:

The Tiktaalik fossils were discovered in 2004 by paleontologists Neil Shubin, Farish Jenkins, and Ted Daeschler in the shallow waters of the Arctic. The first complete skeleton of a Tiktaalik was discovered in 2004 when researchers from the University of Pennsylvania used a remote control submarine to search the bottom of shallow waters.

The body of the Tiktaalik has fish-like features such as fins and fleshy lobes scattered throughout the body. However, the head of the Tiktaalik is adapted to move around in the shallows and capture prey. The back of the head is equipped with eyes and ears. The mouth of the Tiktaalik is also rather fish-like, with a large number of sharp teeth. Tiktaalik remains the best proof that fish evolved into amphibians and eventually evolved into the first walkers on land.

Introduction:

Early life on Earth was limited to single cells for about 3 billion years. The first animal life is found in rocks dated about 530 million years ago. However, the first animals were very simple compared to modern animals, lacking eyes, hearts, brains, and most other organs. But sometime before the first animal, early animals with backbones (vertebrates) appeared. What was the environment like where the first vertebrates lived? How did they survive? A new fossil discovery is shedding light on this problem. This incredible fossil was found in 2004 near the village of Nares Lake.

What Is Tiktaalik?

The Tiktaalik is a 375 million-year-old, semi-aquatic creature that is among the most important finds of the past decade. It is a creature with a head, neck, ribs, and rudimentary limbs. This creature is important because it bridges the gap between the fishes and the land animals. It is the first creature to have adapted to life on land.

The importance of Tiktaalik fossils being found in the Canadian Arctic has shed a lot of light on the early development of life on Earth. It is vitally important that we learn from this development. The scientific paper about Tiktaalik explains that the head to body ratio of this creature was similar to that of a human and this creature had the ability to use its fins in a more efficient way.

Explanation:

Tiktaalik, meaning ‘large freshwater fish’ in the language of Inuktitut was a fish that lived in the Devonian Period. The fish had a jaw, neck, and other characteristics that show that it is a transitional fossil between fish and tetrapods. It was a predator that lived in shallow water and ate smaller fish, but it also had traits like lungs that indicate it could breathe air and a neck and jaw that show it crawled out of the water onto land.

The Tiktaalik roseae was a very large fish, approximately 2.5 meters long. And was discovered in 2004 by Neil Shubin of the University of Chicago and other paleontologists. Since it was discovered 4 years ago, it has been the catalyst for many other related fossils to be found because of their similarities to the Tiktaalik.

Extinct Species Of Sarcopterygian:

Tiktaalik is an extinct species of sarcopterygian (lobe-finned fish). And it is the best transitional fossil known that shows the transition from fish to tetrapod. It is a very important fossil to be discovered since it helps scientists to understand the process of the evolution of the first amphibians from fish ancestors.

Shape:

Tiktaalik was a large, fish-like animal with a flat head and eyes on top of its head. Tiktaalik could walk on land with four short legs and breathe air with their lungs. Although it probably spent most of its time in the water. Tiktaalik wasn’t a land-dwelling animal, but neither was it completely aquatic. It had features that made it a successful transition from water to land, but it still had features that made it successful as an aquatic animal.
