Earth's craters are enduring testaments to direct asteroid hits. And though millionsâin some cases billionsâof years of erosion have made it difficult to determine the exact size of the meteorites, there is a general scientific consensus around the world's largest craters, which mark the largest asteroid impacts.

Quick Answer. Tiger sharks have a row of 24 teeth in their upper jaw and a matching set of 24 teeth in the lower jaw, totaling 48 teeth. Tiger sharks have a square jaw structure, and each of their teeth are built with cutting and sawing mechanisms. Continue Reading.
So 19 teeth a week = 988 teeth a year x 30 years = 29,640 teeth per year. Let's add (48 teeth x 5 rows of development) = 240 currrent teeth. 240 + 29640 = 29880 teeth during a white shark's lifetime! Now that's a sciencey looking number, but it's just a number with very little (if any) scientific basis. Remember this story the next time you see an outragious number in any shark fact.
