It's hardly a fundamental law. It also only applies to fully formed complex organisms, not the gradual development of life from pre-life.
"We have already found fully-preserved soft organic tissue in the bones of dinosaurs, which are alleged to be "70 million years" old -- despite the fact that it is BIOCHEMICALLY-IMPOSSIBLE for soft organic tissues to last more than 100,000 years (let alone being still perfectly-preserved and elastic).
First - It was not fully preserved. Second - the preservation of tissue relies on the conditions it is found in. Degradation requires microorganisms and mineralization requires water. If neither are present the limits of preservation are unknown. The stratum the fossil was found in was dated to be older than 100,000 years. Third - evolution says nothing about how long an organism can survive. Sharks, turtles, nautaloids and some lobe-finned fish predate most dinosaurs, yet there are extant species.
Hey! You forgot the horseshoe crab! :-)
