It seems there might be a typo in your question. If you meant "sagittal crests," these are bony ridges found on the skulls of some animals, including certain primates and hominins. They provide attachment points for strong jaw muscles, indicating a powerful bite. In evolutionary terms, the presence of a sagittal crest can reflect dietary habits and the size of the individual, with larger crests typically associated with greater muscle mass and stronger chewing abilities.

Do you have to have the whole deck of playing cards while playing the card game spoons?
From a standard 52-card deck, select the cards numbered for the number of players and below (for example, for five players, use all four aces, twos, threes, fours, and fives). Place a spoon for each player but one in the center of the table (four spoons for five players). Each player is dealt four cards, and the goal is to get all four of one number. Players simultaneously choose one card from their hands and pass it to the left. When a player collects all four of one number, he or she takes a spoon from the center of the table, and the other players must immediately try to grab a spoon of their own. The player left without a spoon loses the round and is eliminated; remove a set of four cards from the deck and continue.
