Was there fish before dinosaurs?

Before T. rex there was B. rex, a giant armored fish that was “king” long before the dinosaurs, according to a new study. A team of scientists discovered the fossils of Bothriolepis rex, a new giant in the group Antiarchi — ancient fish with armored plates covering their head, shoulders and front fins.

Who ruled the world before dinosaurs?

Pareiasaurs roamed the planet for some 10 million years leading up to the extinction event some 252 million years ago. That extinction is thought to have wiped out 90 percent of species living at the time, creating the void that the dinosaurs and many other animals would occupy.

When was the first human born?

seven million years agoOn the biggest steps in early human evolution scientists are in agreement. The first human ancestors appeared between five million and seven million years ago, probably when some apelike creatures in Africa began to walk habitually on two legs.

Are Sharks older than dinosaurs?

As a group, sharks have been around for at least 420 million years, meaning they have survived four of the “big five” mass extinctions. That makes them older than humanity, older than Mount Everest, older than dinosaurs, older even than trees. It is possible that sharks just got lucky in the lottery of life.

What is older than a dinosaur?

Looking at a millipede today gives you a glimpse into the distant history of life on Earth.

Are sharks dinosaurs?

Sharks. … Today’s sharks are descended from relatives that swam alongside dinosaurs in prehistoric times. In fact, the largest predator of all time was a shark called a Megalodon. It lived just after the dinosaurs, 23 million years ago, and only went extinct 2.6 million years ago.

Before the dinosaurs roamed the earth, a number of other species did — including other large sea reptiles and mollusks. … These massive eruptions released carbon dioxide and other chemicals that warmed the globe and ruined the climate for the species.

When was Adam and Eve born?

They used these variations to create a more reliable molecular clock and found that Adam lived between 120,000 and 156,000 years ago. A comparable analysis of the same men’s mtDNA sequences suggested that Eve lived between 99,000 and 148,000 years ago1.

Where did dinosaurs live on Earth?

Dinosaurs lived on all of the continents. At the beginning of the age of dinosaurs (during the Triassic Period, about 230 million years ago), the continents were arranged together as a single supercontinent called Pangea.
