What animal did Sharks evolve from?
Most scientists believe that sharks came into existence around 400 million years ago.
That’s 200 million years before the dinosaurs.
It’s thought that they descended from a small leaf-shaped fish that had no eyes, fins or bones.
These fish then evolved into the 2 main groups of fish seen today..
Can dinosaurs be alive?
Today, paleontologists have made a pretty much open-and-shut case that dinosaurs never really went extinct at all; they merely evolved into birds, which are sometimes referred to as “living dinosaurs.” … Granted, Phorusrhacos went extinct millions of years ago; there are no dinosaur-sized birds alive today.
What killed the Megalodon?
A new study suggests that a tsunami of cosmic energy from a supernova killed off large ocean animals – including the huge megalodon shark – 2.6 million years ago. A shower of particles may have spelled curtains for the megalodon, a school-bus-sized shark, 2.6 million years ago.
What came after dinosaurs?
No! After the dinosaurs died out, nearly 65 million years passed before people appeared on Earth. However, small mammals (including shrew-sized primates) were alive at the time of the dinosaurs.
What was the first shark ever?
The Silurian Era: The First Sharks 450 million years ago, during the Silurian period, sharks first began developing as a unique species. During that time, the ocean was filled with a variety of bony fish. One of these fish, the Acanthodian, was the very first ancestor of the modern shark.
Which animal lives for 500 years?
Mediterranean red coral, pictured here in the Adriatic Sea off Croatia, can live for 500 years.
How old is the Megalodon?
The earliest megalodon fossils (Otodus megalodon, previously known as Carcharodon or Carcharocles megalodon) date to 20 million years ago. For the next 13 million years the enormous shark dominated the oceans until becoming extinct just 3.6 million years ago.
What animals are older than dinosaurs?

Did dinosaurs live on Pangea?
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. During the 165 million years of dinosaur existence this supercontinent slowly broke apart.
What came before dinosaurs?
The age immediately prior to the dinosaurs was called the Permian. Although there were amphibious reptiles, early versions of the dinosaurs, the dominant life form was the trilobite, visually somewhere between a wood louse and an armadillo. In their heyday there were 15,000 kinds of trilobite.
What is the oldest man made thing on earth?
Lomekwi 3 is the name of an archaeological site in Kenya where ancient stone tools have been discovered dating to 3.3 million years ago, which make them the oldest ever found.
What is the oldest shark ever?
Greenland sharkScientists believe they have found the world’s oldest living vertebrate*. The massive Greenland shark was found in the North Atlantic Ocean by scientists who estimated it to be up to 512 years old.
Which animal is the oldest?
Ancient chemical traces, known as biomarkers, have revealed that sponges existed at least 635 million years ago and perhaps as far back as 660 million years ago, making them the oldest known form of animal life, a new study finds. The first half-billion years of Earth science were gnarly.
What sharks existed with dinosaurs?
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.
What is the oldest thing on earth?
The zircon crystals from Australia’s Jack Hills are believed to be the oldest thing ever discovered on Earth. Researchers have dated the crystals to about 4.375 billion years ago, just 165 million years after the Earth formed. The zircons provide insight into what the early conditions on Earth were like.
