Yes, that's the outlier, but with a half-life of 5,730 years C14 dating has its limitations beyond 25,000 years since a tiny amount of handling contamination can skew results in a big way.
Using simple math, an object from 26,639bce has retained 3.13% of its original C14, and by about 35,000bce the amount drops below 1% - and by the way, errors in handling, etc. generally make the samples appear younger.
