The phrase "a later study identified" is correct and usable in written English.
You can use it when referring to research findings that were published after an earlier study, indicating that new information has been discovered.
Example: "While the initial research suggested a correlation, a later study identified specific factors that contributed to the observed effects."
Alternatives: "subsequent research revealed" or "a following study found".
