Bite of Bygone Days is a puzzle in Professor Layton and the Miracle Mask. The puzzle must be solved in order to progress the story.

Puzzle

This fossil was found on a riverbed.

Close examination revealed tooth marks, suggesting that it was formed when some kind of ancient fish bit into something tasty.

Can you tell which one of the fish pictured in the book made these tooth marks?

Hints




Click a Tab to reveal the Hint.

The first thing to notice is the number of tooth marks. There are six, three on each side. That must mean the fish that made this bite mark has three pairs of teeth.

Compare the three fish. Each of them has three pairs of teeth on either the upper jaw or the lower jaw.

C has rounded teeth, but that doesn't necessarily mean it couldn't make this bite mark.

Is there anything else about the fish that sets apart? Maybe the position of the teeth?

Take another look at the fossil. If the fish had this object in its mouth and bit into it, wouldn't it have more tooth marks toward the edge?

Unless it had teeth arranged on the edge of the fossil...

If the fish had a mouth full of teeth, there wouldn't be such a gap between the tooth marks and the edge of the object after it was bitten.

This fish must not have had any back teeth.


Solution

Incorrect

Too bad.

Don't worry too much about the shape of each fish's teeth.

Correct

Correct!

The answer is A.

The shape of the teeth is irrelevant. Looking at the bite marks as a whole, you can see that only three pairs of front teeth made an impression, so only a fish without any back teeth could have made these marks.
