The mass extinction of dinosaurs were caused volcanoes that cause global warming with their toxic gases, therefore, killing the plants, starving the plant eating dinosaurs to death, and with no more plant eating dinosaurs, the meat eating dinosaurs died, too.

Of course, "halflife" is not the correct term to use in this context, so I am supposing that you are asking how long as in "how many years of use" or "how many rounds fired" can you expect an M16 to function. This is also called "service life". The answer depends entirely on how the machine is treated. If it is properly cleaned and has minor parts replaced as they wear and break, the rifle will last for many years and/or many tens of thousands of rounds. You can research the endurance testing that the US Army has employed to determine the tolerance to hard use. "Halflife" refers to radioactive material and is the amount of time required for half of the material to decay.

Radiocarbon dating is not used for dinosaur bones because dinosaurs lived millions of years ago, and radiocarbon dating is only effective for dating objects up to around 50,000 years old. Dinosaurs are too old for this method to accurately determine their age.
What dinosaur use to eat Dilophosaurus dinosaurs
I am happy to know the colors of dinosaurs. However, I can't think of any practical use for that knowledge except to impress other people who like dinosaurs.
Aww, ya just did.
Dinosaurs would evolve, again. They would invent really big internal combustion engines, and use dead humans for fuel.
