No. And you are so far off as to render any opinions you have ever expressed here about dating as worthless.
Fossils are dated through radiometric dating, not radiocarbon dating.
Radiocarbon dating is suitable only for dating things once alive (in other words, not fossils), and extends back only some 50,000 years.
There are many forms of radiometric dating. Here is a good summary: Radiometric Dating: A Christian Perspective by Dr. Roger C. Wiens.
And Leakey didn't do any dating himself. He worked with geologists and other specialists who identified volcanic layers above and below the layers from which the fossils came (fossils can't be dated directly). Those specialists then did the dating. They obviously would do multiple samples from many areas in an attempt to understand the stratigraphy of the region and the ages of the different layers.
If you want to badmouth the evolutionary sciences, shouldn't you learn something about them first, so as not to look silly when you post?
