A.
The organisms that formed them likely also lived during the Paleozoic era.
B.
The organisms that formed them must have evolved from trilobites.
C.
The organisms that formed them are still living in modern times.
D.
The organisms that formed them likely went extinct before the Paleozoic era.

The correct conclusion the scientist can draw about the other fossils found in the same rock layer as the trilobite is:
**A. The organisms that formed them likely also lived during the Paleozoic era.**
This conclusion is valid because fossils found in the same rock layer are typically of organisms that existed at the same time, given that the rock layer formed concurrently.
