Q:

Were there any dinosaurs that swam?

A:

True dinosaurs were not swimmers. There were a number of very large aquatic reptiles that lived during the age of the dinosaur, but they were not technically dinosaurs. These creatures belonged to one of several other groups, such as ichthyosaurs, plesiosaurs and mosasaurs, which were types of marine reptiles.

Full Answer

Inherent in the definition of dinosaur is its status as a terrestrial animal. Like other land animals, some dinosaurs, like the baryonyx, may have been able to swim if they found themselves in water, but there is no conclusive scientific evidence to support this. Even massive, long-necked dinosaurs such as apatosaurus, once thought to have spent its entire life submerged in deep water, are, as of 2014, believed to have been terrestrial forest dwellers.

  • Q:

    Are there animals alive today that lived beside dinosaurs?

    A:

    There are some animals on earth that can be traced back to the Mesozoic Era when dinosaurs walked the earth; these animals include monotremes such as the duckbill platypus, reptiles such as the crocodilians and sea creatures such as the sea urchin. For the most part, the animals that are alive today have made evolutionary changes from the forms they had when dinosaurs were alive. For example, though the event that caused dinosaurs to die out also killed many other reptile species, several surviving reptile species have direct ancestors from that era, including the crocodilians, which are smaller than their Mesozoic ancestors.
