Morphology
Given that 'Pliocene' denotes a specific time interval (5.3–2.6 Ma) and 'epoch' means a geological time subdivision, the phrase 'Pliocene epoch' is directly compositional: it is the epoch called the Pliocene. This follows a straightforward naming pattern (name + category) found across languages, so a learner who knows both constituents will understand the meaning.
Etymology
Pliocene epoch comes from Greek parts: plio- meaning 'more' and -cene meaning 'new'. Scientists used the name to show this time was 'more recent' than the older Miocene, which is why it refers to the geological period about 5.3 to 2.6 million years ago.
