Giant Fossil Plants - Horsetails / Calamites

Our horsetail plants today are little shrimps compared to what we see in the fossil record! In NY we see them typically reach 24-30 inches. In Chile they can be 20-24 feet tall! However, the fossil record shows them the size of trees! ....90 feet tall! From a creationist standpoint everything has been getting dumber, shorter and uglier since our magnificent beginning!
