Protosuchia is an extinct order of early long-snouted or crocodile-like archosaurs that lived during the Triassic period, around 245-201 million years ago. They were one of the first groups of crocodile-like animals to evolve and were likely fish-eating, semi-aquatic predators. The name Proto Suchia means "样子 first crocodiles" or "proto-crocodiles" in Greek and Latin.
The term "Protosuchians" refers to a group of archaic crocodile-like extinct reptiles that lived during the Early Cretaceous period, from around 145 to 100 million years ago. They were among the first cousins of modern crocodilians.

The name "Prototheria" comes from the Greek words "proto", meaning "first" and "therion", meaning "beast" or "animal", indicating that this group is thought to be the earliest known lineage of mammals.
A prototroph is an organism that can synthesize all the organic compounds it needs to survive and grow using its own genetic information and energy from the environment, without requiring supplements or external sources of nutrients. In other words, a prototroph is a self-sufficient organism that can produce all the necessary molecules, such as amino acids, nucleotides, and fatty acids, through biological processes.<br><br>In contrast, an auxotroph is an organism that cannot synthesize certain essential compounds and requires supplements or external sources of nutrients to survive.
