Pterosaur fossil found with preserved egg

An ancient female pterosaur fossil has been found in China alongside one of its own eggs.
The discovery of the egg indicated that the pterosaur was female offering researchers a rare opportunity to easily determine the gender of the find. At 160 million years old the fossil egg was seemingly well developed indicating that the pterosaur must have been very close to laying it at the time of death.
For fossil hunters, it represents one of those breakthrough moments. A pterosaur has been found in China beautifully preserved with an egg. The egg indicates this ancient flying reptile was a female, and that realisation has allowed researchers to sex these creatures for the first time.

Thanks for the details and I was also pointing out the same thing that only asteroid couldn't be responsible for the Mass extinction of the whole species as it is believed, multiple factors played a role in it. No scientist is suggesting that the extinction of the dinosaurs (a group of animals, not a species) was an instantaneous event. There are some 300 known groups of dinosaurs that lived over a 165 million year period and the last of these groups went extinct 65 million years ago. The picture painted, appears the dinosaurs were on their way out anyway and impact theory states that it was a... [More]

There are some 300 known groups of dinosaurs that lived over a 165 million year period and the last of these groups went extinct 65 million years ago. The picture painted, appears the dinosaurs were on their way out anyway and impact theory states that it was an impact that helped them along the way. What lends credence to this fact, is that other groups went extinct at the same time. Which would be evidence against a disease or unique event to that one group. I think... [More]

Yes I think you guys have got it right. All around the world there is evidence of fine ash deposits that could have been high in the atmousphere blotting out sunlight. Plantlife would have been greatly reduced so no food and very cold.

I hope they get to work on creating Jurassic park. To quote Dr. Ian Malcolm: "Oh, yeah. Oooh, ahhh, that's how it always starts. Then later there's running and screaming."

To quote Dr. Ian Malcolm: "Oh, yeah. Oooh, ahhh, that's how it always starts. Then later there's running and screaming." If you want to go with scaring people, always go with the classics, pull something from Frankenstein for example. Pulling from a horror movie is sorta.... enh.

If you want to go with scaring people, always go with the classics, pull something from Frankenstein for example. Pulling from a horror movie is sorta.... enh. What are you talking about? I pulled a "The Lost World: Jurassic Park" quote since the comment mentioned it, along with the topic of dinosaurs. I don't see a quote from Frankenstein being at all in the same ball park until I see neck bolts sticking out of Velociraptors. And your logic is an oxymoron. Always quote the classics like Frankenstein, but pulling one from a horror movie is sorta enh? You do know Frankenstein is a classic horro... [More]

I assure you,Frankenstein was a book long before it was ever a movie. What I was trying to do, and I failed utterly,was to say something along the lines of "Oh yes, you should always base your expectations of science off of fears instilled in you from horror films." I was sorta cranky yesterday from a bad day at work, sorry. LOL! That's alright. We all have our days. I wasn't really comparing scenarios from the movie per say, just because I never really encountered a carnivorous dinosaur before. I found the quote funny personally. However, if a carnivorous dinosaur is someday reborn by scienti... [More]

Oh, and Jurassic Park was a book published in 1990. The movie came out in 1993 Ah, but that quote came from one of the later movies, Lost World, which wasn't even in the book. Glad you understood.
