The influence of paleontology on ecological sciences can be traced back to at least the 18th century.
Notes on verification
Confirmed via convergent independent sources (Wikipedia articles on Paleoecology and History of Paleontology, plus a scholarly book description) that paleontology and ecology share overlapping historical origins dating to the 1700s-1800s, prior to their formal disciplinary split in the 19th century. No single source states the exact claim verbatim, but the historiographical substance is well-supported.
