Dr. Dino asked Emek and Luna to prepare a museum display using data from the dinosaur excavation. They created a chart showing 14 Triceratops fossils, 9 Stegosaurus fossils, 12 Hadrosaur fossils, and 7 Ankylosaurus fossils. While checking their work, Luna noticed the chart listed 10 Stegosaurus fossils instead of the recorded 9. They corrected the mistake, reviewed the chart again, and used the accurate information to build the exhibit. Visitors enjoyed comparing the fossil discoveries, and Dr. Dino thanked them for their careful work.

Hint
Look for the dinosaur whose chart value did not match the recorded count.
Luna noticed that one fossil count in the chart was incorrect. Which dinosaur's count needed to be corrected?
TriceratopsStegosaurusHadrosaurAnkylosaurusCorrect! The Stegosaurus count was corrected from 10 to 9.
Not quite. Check which fossil count was recorded incorrectly in the story.
Next🎉 Congrats! You got this question!
Hint
Add the corrected fossil counts for all four dinosaur species.
After correcting the chart, how many fossils were shown altogether?
Correct! The corrected chart shows 42 fossils in total.
Try adding the corrected counts: 14, 9, 12, and 7.
Next🎉 Congrats! You got this question!
Hint
Compare the corrected counts for Stegosaurus and Hadrosaur.
A visitor says the corrected chart still shows more Stegosaurus fossils than Hadrosaur fossils. What is the best response?
The visitor is correct because 9 is greater than 12.The visitor is correct because the chart was changed.The visitor is not correct because Hadrosaur has 12 fossils and Stegosaurus has 9.The visitor is not correct because Triceratops has the fewest fossils.Correct! Hadrosaur has 12 fossils, which is more than the 9 Stegosaurus fossils.
Check the corrected chart and compare the two fossil counts carefully.
