1. Living mollusks have had shells dated up to 2300 years. 
2. New wood from living trees has been dated at 10,000 years
3. Mortar from Oxford Castle (built 785 years ago) was dated at 7,370 years
4. Seals, freshly killed, were dated 1,300 years old. Mummified dead < 30 years old were dated 4,600 years old
5. Comparison of radiocarbon dates for artifacts of known historical age (from Egypt for example) reveals radiocarbon years and calendar years are not the same.
6. Conflicting data is found and sometimes know to be arbitrarily selected. D. Collins says, "It is not generally appreciated that up to a third of all dates have to be rejected as impossible...". (Reed CA. Animal Domestication in Prehistoric Near East, Science, 130, P1630, 1959)
7. Earth's magnetic field decay. Measurements between 1835 and present, indicate 1/2 life of magnetic field of 1,400 years. This would have markedly effected the rate of radiocarbon formation over time.
8. Robert Whitelaw - Summary of 15,000 reports from literature

1. Only 3/15,000 gave infinite dates
2. Only occasional date > 50,000 years
3. If very old earth, then the world wide samples should yield 20,000 undatable specimens for each datable one.
4. Some coal, oil, and methane dates < 40,000 years (produced dates of 100,000,000 years old), but these may simply be anomalous data.
5. Samples from eras > 50,000,000 years ago gave dates < 40,000 years
6. Many dates of extinct flora/fauna < 10-30,000 years.
7. If arrange the 14C dates in age order, then we would find a sharp drop off in numbers immediately following the flood (4,500 - 4,900 years ago)
8. In 500 years after creation, no identifiable human death dates. In 450 years after the flood, only 8 human death dates.
