At a dinosaur dig site, Emek and Luna helped the excavation team collect fossils from different species. By the end of the morning, they had found 9 Triceratops fossils, 6 Stegosaurus fossils, 11 Hadrosaur fossils, and 4 Ankylosaurus fossils. Instead of leaving the discoveries in separate boxes, they organized the counts into a simple chart on the fossil record wall. The chart made it easy for everyone to compare the findings and quickly see which areas might contain more fossils. Using the information, the team chose where to continue digging, and the excavation became more organized and successful.

Hint
Compare the counts for Hadrosaur and Triceratops.
Based on the chart, which statement is true?
Stegosaurus and Ankylosaurus together have more fossils than Hadrosaur.Triceratops has fewer fossils than Stegosaurus.Hadrosaur has 2 more fossils than Triceratops.Ankylosaurus has more fossils than Triceratops.Correct! Hadrosaur has 11 fossils and Triceratops has 9, so the difference is 2.
Check each statement by comparing the fossil counts in the chart.
