Eurypterids fossils are known from all continents, and have such amazingly good preservation that their external structure is the best known of all extinct animals. Because of their long tails and the spine-like appendage at the tip, the eurypterids have been called sea-scorpions.
Mission creep is the expansion of a project or mission beyond its original goals, often after initial successes. Mission creep is usually considered undesirable due to the dangerous path of each success breeding more ambitious attempts, only stopping when a final, often catastrophic, failure occurs. The term was originally applied exclusively to military operations, but has recently been applied to many different fields.
