It's a bit outdated, but Quézel (1978) suggests the flora of the Mediterranean region of Africa is not much different than today:
It is concluded that the Mediterranean flora is relatively old and goes back at least as far as the middle Miocene
- See here for a scale of Geologic time. The middle Miocene would be ~10mya, so the above quote encompasses your time of interest.
However, I personally find this claim to be difficult to believe, especially due to documented variability at smaller scales: (e.g., Moreau 1963, Carlo et al 2009, etc.)
Other literature, unsurprisingly, points toward the fact that humans very likely modified their surroundings in noteworthy ways once on the scene. For example, Thompson et al. 2021:
Archaeological data and principal coordinates analysis indicate that early anthropogenic fire relaxed seasonal constraints on ignitions, influencing vegetation composition and erosion. This operated in tandem with climate-driven changes in precipitation to culminate in an ecological transition to an early, pre-agricultural anthropogenic landscape
Perhaps Gardner (1935) would also be of interest (I don't know, I don't have access).
Conclusion: I don't know the answer and only compiled the above in about 5 minutes of Google Scholar searching. I would guess that both the flora and fauna were likely somewhat dynamic across the time period you're asking about, and certainly, spatial physiognomic heterogeneity exists even today.
To narrow further searching, make sure you're using technical terminology where possible (e.g., late Pleistocene, Chibanian, etc.).
