No, Technically cordata were introduced in the late Camrian period in the form of small fish.. But The Devonian period is when the first large sharks and fish began to apear, I also believe that amphibians were on land in the mid-late devonian, and were abundant in the Carboniferous.
GO SIMPLE PLAN!!!!!!!!!!!!!!!!!!!!!!!! sorry...
The earliest known vertibrate is Haikouichtys has been found in 530 million year old rocks fom the Cambrian Period of the Paleozoic Era.
The first known reptiles appeared about 320 million years ago. That was during the Carboniferous period. The Carboniferous period was part of the Paleozoic era.
545-500 Million Years Ago
The Paleozoic Era
No scientists know yet.
False false
That is purely an accident of evolutionary history.
This all depends; Paleontologists are usually in an office, or, they are out doing field work. If they are in an office this could also mean in a classroom, seeing a lot of paleontologists work as university professors.
fossil correlations -have fun on study island :)
Desert Storm under George H.W. Bush was the quickest war in American history. I believe it was over in 100 hours.
Paleontologists study fossils, archeologists study past human life, climatologists can study past climates, geologists can study various things about Earth's past - the point being that a number of different scientists may study fossils in their disciplines.
When mammoth remains are found, they are usually turned over to paleontologists. Paleontologists preserve them in controlled environments at natural history museums.
---- Informations: Paleonthology-is the study about fossils Paleontologists-are persons who study fossils ---- Other Questions??
A petrologist studies the history and structure of rocks. Geologists and paleontologists also have great interest in rocks.

I believe it' Texas' history . :)
Palaeontologists uncover, examine, categorize and publish about fossils. An important part of what we know of the natural history of life on Earth comes from fossil evidence.

I believe they call it "Earth". I believe they call it ''History''.
no i dnt believe you can
The evolution of jaws is believed to be used originally for respiratory purposes. However, it is important to the history of vertebrates mainly because it allowed for more efficient eating.
