Paleontologists at Grand Staircase-Escalante National Monument discovered a new ceratopsid skull. The skull has a moderate-sized neck frill, indicating a small body, and has two short horns. The table shows rock formations at the monument and the location of known fossils relative to those formations.
Based on the evolutionary relationship suggested by the anatomy of the skull, in which of the following formations was the skull found?
Dakota
Wahweap
Kaiparowits
Canaan Peak
by studying the limbs and fossils of different animals, such as a horse leg and a human leg, scientists have noticed that there are similarities in their bone structures. this is evidence that their bone structures and limbs may have evolved in similar ways.
The scenario is describing a relationship known as causation .
The scenario is describing intermediate fossils .
The scenario is describing a relationship known as correlation .
The scenario is describing transitional fossils .

Developmental Biology - Embryology Many scientists use what an organism looks like as an embryo, or embryology, as evidence for evolution. The embryos of most vertebrates look very similar and have similar structures. For example, fish, bird, rabbit, and human embryos are similar in appearance in early stages. They all have gill slits and a tail with muscles to move it. Later as the embryos develop, they become less and less similar. What does the study of embryology show when comparing most vertebrates?arrow_forwardExplain why it is difficult to use carbon-14 dating on 100-million-year-old dinosaur fossilsarrow_forward
