Question

1. a second fossil is found with solid bones and mammal-like teeth. how might scientists classify it differently from rexoraptor?

Explanation:

To determine the classification, we analyze the features: solid bones and mammal - like teeth. Rexoraptor (assuming it's a dinosaur) has hollow bones and reptilian teeth. Dinosaurs are reptiles, while mammals have solid bones and specialized teeth. So the new fossil, with mammal - like traits, would likely be classified as a mammal (or mammal - like reptile/ancestor) instead of a dinosaur (like Rexoraptor).

Answer:

Scientists would likely classify this fossil as a mammal (or a mammal - like organism) rather than a dinosaur (like Rexoraptor). Rexoraptor (a dinosaur) has hollow bones and reptilian - like teeth, while this fossil has solid bones and mammal - like teeth, traits more associated with mammals.
