Chinese Fossil Shows Early Birds Supped on Seeds

Chinese Fossil Shows Early Bird Supped on Seeds

Paleontologists working in northeastern China have uncovered yet another extraordinarily well preserved bird fossil. The crow-size creature, dubbed Jeholornis prima, lived during the Early Cretaceous period, and its remains provide rare insight into what early birds ate.

According to a report published today in the journal Nature, the beast’s stomach contains more than 50 intact plant seeds--the first direct evidence of early avian seed-eating. Other clues to what the animal ate come from the skeleton itself. Zhonghe Zhou and Fucheng Zhang of the Chinese Academy of Sciences in Beijing, the researchers who describe the fossil, note that features of the jaws, teeth and hyoid bones are consistent with a seed-eating habit.

Whether Jeholornis obtained the seeds from cones in trees or on the ground is unclear. But its body appears to have been well adapted to powerful flight and to perching in trees. This is surprising, Zhou and Zhang remark, considering how primitive a bird it is. The fossil also exhibits a long, bony tail similar to that of dromaeosaurs, thus bolstering the evolutionary link between birds and theropod dinosaurs.

"This discovery, together with many others in recent years," the authors conclude, "suggests that by the Early Cretaceous, early birds had not only diverged significantly in morphology, size, and ecology, but had also differentiated with respect to feeding adaptation." --Rachael Moeller

Interesting. It looks like true birds came along much earlier than believed.

It also has a long, bony (dinosaur) tail.

It's dated younger than Archeopteryx

This would be one of those non-existent transitional forms, then?

It's all a Chinese commie athiest plot, no doubt...

Just one more fossil to create two new gaps.

Or another example of the Devil's trickery and the gullibility of godless evolutionists. (/sarcasm)

Acceptance of fossils

It had teeth. Did it chew seeds thoroughly before swallowing? Was it a strict vegetarian? Did it migrate with the seasons? At least two more gaps where there was one.

This is proof that Darwin was a fool.
This is clear evidence of Noah's Ark.
This is an obvious fraud.
Fossil? What fossil? I don't see any fossil.

Jeholornis prima is the latest in a host of ancient birds found recently from places as far afield as Spain, Madagascar and China that illuminate the earliest stages of bird evolution. They come from an interval somewhat later than that of Archaeopteryx but show that the major features of modern bird form were sketched out in this period.

I wonder if it tasted like chicken?

Even as a kid, it seemed to me that
chickens having scaled feet and long
claws was like rabbits fitted out
with bayonets.  Dissonant.  Of course,
back then, when kids pointed out that
the continents looked like they fit together,
the teachers chuckled and moved on.
