Excerpt:

Dinosaur dioramas* don’t display flowers and grasses—supposedly because they had not yet evolved. But it takes only one piece of the right kind of evidence to disprove a whole paradigm. Amazing amber fossils from Burma (now Myanmar) refute the idea that flowers were absent in the supposed Age of Reptiles by showing the abrupt appearance of fully-formed flowers.

Publishing in Journal of the Botanical Research Institute of Texas, three scientists described a cluster of small, possibly rose-like flowers encased in amber assigned an age of 100 million years—well within the timeframe that evolutionists ascribe to dinosaurs.1 The petal-less flowers looked unique enough for the researchers to give their plant a new name, Micropetasos burmensis. Nevertheless, the pollen grains adhering to the flower stigma and tiny pollen tubes frozen in their growth down the flower style clearly show that flowers back then were operating just like modern living flowers.
