Is Tiktalik a vertebrate

It's a vertebrate, there's no doubt about it.

It can be seen by pressing 1L to give.

Tiktalik is a transitional species of the class Ichthya and Amphibians.

Ichthyidae Amphibians are both subphylum of vertebrates.

So it must be a vertebrate.

Yes On April 5, 2006, a scientific expedition discovered an ancient fish fossil in the Arctic that is 100 million years old, filling the evolutionary gap between aquatic and terrestrial animals. And it was named "Tiktalik", a "ichthypod" that belonged to the order Paleovertebrates. The Paleovertebrate order is represented by the Paleoospondylus traquair, which is found in the old red sandstone of the Middle Devonian in Achanaras, north of Scotland, with hundreds of signs.

These small fish are only 43 mm long. From its basic structure, it does not appear to be related to any early fish, such as the absence of a single armor-like exoskeleton. Although the skeletal shape and location of the head are many difficult to identify, the slender spine is well developed, well-segmented, and fully ossified.

The medullary arc and pulse arc are also vivid. Many pairs of bones in the ear area, crest of the brain cavity, nasal area, and base of the skull are intact. Thoracic and pelvic fin fragments are also present.

The crooked tail is well developed.

is a fish that is extinct. Titarik is considered to be a species between fish and biothernia. Unlike many of the more fish-like fossils of the past, its "fins" have primitive carpal bones and simple toes, indicating that they can bear weight.

A closer look at these junctions suggests that although the Titarik fish may not be able to use them for walking, they may be able to support their bodies, as if they were standing on the ground [4]. The bones of the front fin show that they may have a lot of musculature to indicate that they have well-developed muscles and have the ability to bend like a wrist. These wrist-like features can help Titaalik fish stabilize the bottom of their body when moving quickly [4][5].

The stomata located above the top of the head are also a notable feature, suggesting that they have lungs that function as well as their gills. Titalik can use this structure in shallow seas, where temperatures are higher and oxygen levels are lower. This more evolutionary structure also promotes the evolution of the rib cage in a stronger direction, a key structure for terrestrial organisms [2].

Stronger ribs allow the body of the Titaalik to venture out of the water at any time. Titaalik also lacks many of the features that fish possess The bony disc located near the gills restricts the rotation of the head, which also makes them the first fish to have a neck. This also gives them more freedom when hunting, both on land and in shallow water [5].

Speciation of vertebrates in the Late Devonian, adaptation of the offspring of pelagic meat-finned fishes: * Panderichthys: adapted to silt shallow life.

Titarik: has fins that resemble limbs and can walk on land. *Acanthostega:

There are eight-toed feet. *Ichthyostega: has feet.

The Titalik is an over-the-top fossil that has the same status as a tetrapod like an Archaeopteryx. They demonstrate the existence of a transitional species among many quite different vertebrates.

Tiktaalik, also known as fishibian or fishapod, is a large scaly fish that makes a perfect transition between aquatic and terrestrial animals. The Tiktalik has fish-like scales, fins, jawbones, and a mouth, but it has only a thin skull, a neck that can move to hunt for food, ears that can hear sounds on land and water, and wrist joints like many land animals.

Yes This is a fossil that freezes the moment when an animal evolves to shore. An American scientific expedition team announced on the 5th that they had found an ancient fish fossil in Ellesmere Island in the Canadian Arctic region. It fills a long-sought gap in Darwinian evolution

Some fish leave the ocean and walk on all fours to land. The researchers named the new species found in the frozen rock "tiktaalikroseae". In the ancient dialect of the Nufort region of Canada, where it was found, "Tiktalik" means "to see a huge fish in shallow water".

It's a fish, it's a tetrapod "It's a fish, but it's a surprising collection of the characteristics of a land animal. This animal represents the transition from aquatic to terrestrial animals, and we humans also belong to the category of terrestrial animals. The team was led by Neil Shubin, an evolutionary biologist at the University of Chicago in the United States.

The discovery was published in the April 6 issue of the journal Nature. The team said they found well-preserved fish fossils in sedimentary rocks on Ellesmere Island, in Canada's Nufort region, about 960 kilometers from the North Pole. The fossilized skeleton has fins, scales, and other features belonging to large fish, sharp teeth, jawbones 25 cm to 51 cm wide, and a flat body about 4 to 9 feet (about meters) long.

After further research, scientists have discovered on the fossils an important feature of anatomically transitional organisms: although they are still fish, these fish already have important changes that will transform into terrestrial organisms, so they can be called the pioneers of amphibians. The paleontological community has long understood that fish evolved from aquatic organisms to four-legged, spine-based terrestrial organisms hundreds of millions of years ago.

But there has been a lack of strong evidence on evolutionary processes. Because there is a gap in the two paleontological fossils——— Panderichthy and Acanthostega, the former being a fish that lived about 100 million years ago, and the latter being the earliest known quadruped on land on Earth, dating back to about 100 million years ago. Tiktalik fills this gap.

The fossil is 100 million years old, it has the fins and scales of a fish, but the skull is crocodile-like, the eyes are located on the top of its head and the beginning of its neck, and the neck and ribs also resemble land animals. These are features that are not found in fish. "It's a fish, but it's an amazing combination of the characteristics of a land animal.

This animal represents the transition from aquatic to terrestrial animals, and we humans also belong to the category of terrestrial animals. "It's a fish and it's a tetrapod." In addition, the excavation of the "Tiktalik" fossil also provides strong evidence to refute religious creationists.

Religious creationists have claimed that the inability to find transitional organisms between fish and land animals is the missing link in Darwin's theory of evolution.

No! However, some fins can perform a similar function to the feet, such as mudskippers. Those with feet are not really fish! Such as: baby fish, soft-shelled turtle, etc.

No, baby fish are reptiles, and so are soft-shelled turtles, but some fins can play a role similar to feet

Yes, but there are not many with long legs, such as soft-shelled turtles.
