What information did wegener not have that would have strengthen his argument?

Alfred Wegener lacked geological evidence and a plausible mechanism for how continents could drift apart. Specifically, he did not have access to the concept of plate tectonics, which later provided a scientific basis for continental movement. Additionally, he lacked detailed fossil and rock correlation data to bolster his claims about the similarities between separated land masses. This absence of comprehensive evidence limited the acceptance of his theory during his time.
