Something caught my eye in that ICR article,

"Obviously we cannot speak with certainty, for the Bible gives little detail. At the very least, Satan's demons could have selected and indwelt certain men and women, and performed selective breeding experiments to produce over the generations a race of giants. (He could have done the same with animals too, and maybe that's where some of the unthinkable features we see in the fossil record come from."

What is he talking about in the fossil record?
Maybe this...
