Can you have nitrogen atoms in your bodies that existed during the time of the dinosaurs?

Yes indeed. Nitrogen is a stable element and the amount present on Earth is endlessly recycled. While nitrogen atoms spend some time in rocks, in soil, in plant tissues and in animals (where they make muscles), eventually they return to the atmosphere whence they can be breathed in. Because atoms are so small, each human breath holds an astonishing number of them, and assuming that they're pretty well mixed, each breath you take holds - on average - three Nitrogen atoms from a dinosaur, and not just a random dinosaur, but a particular dinosaur. Of course, each of those atoms has spent some time in millions of dinosaurs.

What species existed during the Mesozoic?
Dinosaurs
What kind of animals existed during the Mesozoic Era zone?
dinosaurs
Where are the meat eaters live in?
The fossils of meat eating dinosaurs have been found on every continent and in every type of habitat that existed during the Mesozoic (the Age of Dinosaurs).
When did eoraptor live?
The Eoraptor was one of the first dinosaurs. They existed during the Carnian stage of the Triassic period. That was about 230 million years ago.

Were dinosaurs new kinds of animals that lived in the Cenozoic era?
Dinosaurs first appeared during the Mesozoic, the era before the Cenozoic. All non avian dinosaurs were extinct by the time the Cenozoic began. However, birds, which are a clade of dinosaurs, still existed at the beginning of the Cenozoic and still live today.
Is a pterosaur a reptile?
Yes, pterosaurs were flying reptiles. They existed alongside the dinosaurs during the Mesozoic era. The largest known pterosaur had a 30 foot wingspan, and was the largest known flying animal to have ever existed.
Why is it possible that you share some of the same matter as a dinosaur that lived millions of years ago?
Elements and compounds are recycled in nature, so that carbon and oxygen and nitrogen in our bodies may have also existed in the bodies of dinosaurs who have decomposed back into the biosphere. The physical integrity of atoms can only be affected by nuclear reactions such as fission and fusion, and such reactions are very uncommon on Earth. These days (as in, the last few billion years) the only atomic nuclei on Earth to be affected naturally are those that are subject to radioactive decay (various heavy elements and isotopes etc.). Therefore, the vast majority of the atoms that exist today also existed during the Mesozoic, when dinosaurs ruled the Earth, considering that living beings are for the most part composed of stable elements. Those atoms may have taken part in countless multitudes of chemical reactions, and been part of many organisms and inert material since then, but the atoms themselves remain unchanged. Therefore we can safely say that at least some of the atoms that are now in your body existed in the bodies of dinosaurs millions of years ago (and in the bodies of many other creatures that lived even earlier). Living beings constantly exchange matter and energy, through excretion and the like, and millions of years in the future many atoms that are now in your body will be present in the organisms that will exist at that time.
What was it like when the dinosaurs were around?
When the dinosaurs existed, the world was much warmer than it is today. There were many warm, shallow seas. The primary plants included conifers, tree ferns, cycads, and, during the Jurassic, ginkgos. In the early Cretaceous, the last period when non avian dinosaurs lived, the first flowering plants appeared, and, before the extinction of the dinosaurs, early grasses grew near riverbeds, and there were palms and Magnolids. Besides dinosaurs, there were pterosaurs in the sky, and icthyosaurs, plesiosaurs, mosasars, and thalattosuchians lived in the oceans. Many modern animal groups, such as mammals, birds, crocodillians, turtles, frogs, and salamanders evolved during the time that non avian dinosaurs existed.
Was there anything living before the dinosaurs existed?
No, birds are the direct living descendant of dinosaurs. However, studies have found that a gigantic dragonfly called a Meganeuropsis Americana, with a wing span of about three feet lived during the Permian period, 290 million to about 248 million years ago.
During which prehistoric ere did dinosaurs roam the earth?
Dinosaurs and mammals coexisted during the Mesozoic era. If you count birds as dinosaurs, then they still coexist now in the Cenozoic.
