how do あなた think the dinosours died?

They and the ユニコーン were at a party late one night and overslept the 次 morning, so Noah left in his ark without them.

Justin Bieber went back in time and started 歌う and his 歌う is so bad that the 恐竜 got sick of it and started killing themselves

Voldemort built a time machine, he went back in time to the dinosaurs, and Avada Kedavra!'d them all.
I've been waiting so long to say that... :D :D Lol.

They wanted to create a mystery for us to solve...every time we ask how they died they start cracking up in heaven

umm, i rly dont kno.......
thats pretty interesting to kno, i think......

the flood. あなた know, with noah, and the ark, and the 動物 walking side によって side into the ark and no one believed that there would be rain so everyone but noah and his family died...MY MOM HAS SEEN A DINOSAUR!!!! u know, the ones that could fly... i can't think of the name right now but she saw it when she was, like, 10 または something in the everglades in FL... IM NOT KIDDING!

-um magic:)

Meteors.

There is really no answer, many believe asteroids,
some think acid rain, other a flood, who knows?
I LUV 恐竜 AND ドラゴン SO ISH SMART 8D

well, there is a perfectly logical scientific explaination 4 how the 恐竜 kicked the bucket: because they were all depressed and so they commited suicide! lolz :))

I did it

I killed them

Jack Bauer took them all out because he was running out of time they wouldn't tell him where the bomb was.

The world may never know.
