Final answer:

The Paleocene-Eocene Thermal Maximum (PETM) can be indicated by neodymium (Nd) and strontium (Sr) geochemical signals in marine sediment drill cores.

Step-by-step explanation:

The two oceanic features that indicate the Paleocene-Eocene Thermal Maximum (PETM) are neodymium (Nd) and strontium (Sr) geochemical signals. These trace elements are used as indicators of provenance in marine sediment drill cores. In a drill core taken from the Wilkes Subglacial Basin, the analysis of Nd and Sr layers of sediment helped identify the occurrence of the PETM.
