Report: Men and dinosaurs coexisted


Dinosaurs are often portrayed as having lived in a time before man. However, the available evidence shows that man and dinosaur coexisted.
Legends of dragons are found among most people groups. For example, there are the stories of Bel and the dragon, the Kulta of Australian aborigines, St. George and the dragon, and of course many Chinese legends. Often, the anatomical descriptions given are consistent, even though they come from separate continents and various times. These depictions match what we know from the fossil evidence of certain dinosaurs. Thus, dinosaurs are known directly from their fossils, and indirectly from cave drawings, tapestries, textiles, figurines, carvings, bas reliefs, and many oral and written eyewitness accounts, most of which are quite old.

'Dinosaur Plant' Evolution Stories Conflict - plus video - Dinosaurs - Man - Evolution and The Bible

ICR

Cycads, also called "sago palms," are cone-bearing plants with long leathery shoots that often adorn dinosaur dioramas. Though there are about 11 living cycad genera, which further divide into about 300 species, many more once existed but are now known only from fossils.1

The oldest rock layers that contain cycads are supposedly about 250 million years old. However, in a study published in Science, a group of scientists compared the similarities between cycad DNA sequences and did not find the many DNA differences that should have resulted from a quarter-billion years' worth of mutations and evolution.2

Even after applying evolutionary assumptions to make their molecular clock work, most likely including a very slow mutation rate, the researchers' results showed that almost all of today's cycads "only began diversifying 10 million years ago," the study's lead author, Nathalie Nagalingum, told LiveScience.3

So, did cycads emerge suddenly 250 million years ago, according to the evolutionary age assignment given to their first appearance as fossils, or did they suddenly diversify only 10 million years ago, according to the evolutionary age assignment given to their DNA differences? Is either story even close?

Surely this vast age discrepancy cannot be the fault of fossils or DNA, because they were the same in both studies. Instead, the assumption of vast age produces the confusion.

However, the creation model's young age explains these data with no conflicts. Rocks with dinosaur fossils also contain many fossils of animals and plants—including cycads and Wollemi pines—that are essentially the same as their living counterparts.4 They look so similar to living creatures because they were only deposited thousands of years ago after being swept up in one of a number of catastrophic watery surges associated with the year of Noah's Flood.

According to Scripture, which provides eyewitness accounts that go back to the very beginning, there is no such thing as a dinosaur age—at least, not one without people, cycads, birds, marsupials, and other "modern" creatures.5

The molecular clock-based 10-million-year-old cycad divergence described in Science may actually reflect the rapid diversification into many species of those few genera of cycads that survived the Flood and pioneered the post-Flood world only four thousand or so years ago.

Cycads are living reminders that dinosaurs and modern plants and creatures recently shared living space. And the recent cycad dating mismatch is a reminder that evolutionary dates are all based on broken clocks.

Dinosaurs Ate Rice

ICR

Just what did dinosaurs eat?

One way researchers are finding out is by studying coprolites, or fossilized dinosaur dung. And as it turns out, some dinosaurs ate rice plants. But if flowering plants like rice did not evolve until millions of years after dinosaurs lived—as evolution maintains—how could dinosaurs have eaten them?

Some coprolites contain phytoliths, which are uniquely shaped microscopic crystals manufactured by various plant tissues. Most phytoliths are made of silicon dioxide, the same chemical that comprises sand. Scientists examining these tiny grains can often discern from which plant they came.

For example, in 2005, researchers found phytoliths from grass, palm trees, conifers, and other flowering plants in (probably sauropod) dinosaur coprolites from India.1 "It was very unexpected….We will have to rewrite our understanding of its evolution….We may have to add grass to the dioramas of dinosaurs we see in museums," palaeobotanist Caroline Strömberg told Nature News at the time.2

Recently, Strömberg and two of her co-authors from the 2005 study described coprolite-encased phytoliths that are so similar to those made by certain modern rice plants that those found in dinosaur rocks "can be assigned to the rice tribe, Oryzeae, of grass subfamily Ehrhartoideae."3 They collected these samples from the same Indian rock layers, the Lameta Formation, that contained their 2005 finds.

This find joins others that have shown that rice, grass, palm trees, and conifers from dinosaur rocks were essentially the same as their living counterparts. It's as though millions of years of plant evolution never occurred.

The Lameta formation includes sedimentary layers interbedded with volcanic rock layers. It is huge, covering a large area of India.4 The Flood described in the book of Genesis is the best explanation for this scale of upheaval, showing that the fossils found there resulted from the Flood.

Thus, these coprolites show that rice plants existed before the Flood. Either rice had diversified from an originally created grass that was common to many other grasses, like wheat and bamboo, or God created rice grasses separately from other grass kinds. Studies show that rice grasses do not hybridize with other grasses.5 These dinosaur-eaten phytoliths add weight to the idea that rice was a distinct creation from the beginning.

According to Scripture, God created all the grasses, plants, and grazing mammals, along with any grazing dinosaurs like sauropods, by the sixth day of the creation week. As far as what the fossils have shown, Scripture is right.
