Question

this picture shows a fossil of an ancient animal called ursus spelaeus. ursus spelaeus went extinct about 24,000 years ago. many ursus spelaeus fossils have been found in caves. which traits did ursus spelaeus have? select the traits you can observe on the fossil.. rounded ears long legs brown fur covering most of its body front and back legs

Explanation:

To determine the observable traits from the fossil (skeleton) of Ursus spelaeus:

• "Rounded ears": The fossil is a skeleton, and ear shape (soft tissue - related) isn't directly observable from bones.
• "Long legs": By visually inspecting the skeletal structure, the leg bones appear relatively long.
• "Brown fur covering most of its body": Fur is soft tissue and doesn't preserve in fossils, so this can't be observed from the skeleton.
• "Front and back legs": The fossil clearly shows both front (forelimbs) and back (hindlimbs) leg bones.

Answer:

The observable traits from the fossil are:

• long legs
• front and back legs
