To determine which dinosaur species from your options could match the mystery fossil based on its carbon dating between 93.9 million years ago (MYA) and 89.8 MYA, we need to find out the time periods for each dinosaur species:

  1. Zuniceratops - Lived approximately 90 to 75 million years ago (MYA). This fits within the timeframe.

  2. Protoceratops - Lived approximately 75 to 71 million years ago (MYA). This does not fit the timeframe.

  3. Centrosaurus - Lived approximately 75 to 70 million years ago (MYA). This does not fit the timeframe.

  4. Chasmosaurus - Lived approximately 76 to 70 million years ago (MYA). This does not fit the timeframe.

Based on this information, the marking would be as follows:

A Possible Option

  • Zuniceratops

Not a Possible Option

  • Protoceratops
  • Centrosaurus
  • Chasmosaurus
