:00:00. > :00:07.Hi, I'm Ayshah and this is Newsround.
:00:08. > :00:14.There's big dino news from over 200 million years ago.
:00:15. > :00:30.And we say happy 200th birthday to roller coasters.
:00:31. > :00:33.When this wall fell down at a primary school
:00:34. > :00:39.have been found to have construction problems.
:00:40. > :00:43.Most of the buildings have now been repaired,
:00:44. > :00:46.but some people are calling for the councils in charge to do
:00:47. > :00:52.more to make sure that new schools are built properly.
:00:53. > :00:55.To football, and Leicester City still have a chance
:00:56. > :00:59.to get to the next stage of the Champions League
:01:00. > :01:01.despite a 1-0 defeat in Spain to Atletico Madrid.
:01:02. > :01:05.The only goal came after a controversial penalty.
:01:06. > :01:08.Marc Albrighton's foul looked to be outside the box.
:01:09. > :01:11.They'll have to overturn that goal in next
:01:12. > :01:17.Who'd win in a fight - dinosaur or crocodile?
:01:18. > :01:19.Well, you don't have to chose because researchers have discovered
:01:20. > :01:22.the fossil of a creature that was a bit of both.
:01:23. > :01:24.It's helping them find out exactly how crocodiles
:01:25. > :01:27.There aren't many animals older than a dinosaur right?
:01:28. > :01:36.Crocodile-like creatures were around way before that,
:01:37. > :01:43.Now researchers think they've found out
:01:44. > :01:47.how the crocodiles first evolved into dinosaurs - by studying
:01:48. > :01:52.a fossil of a creature called a teleocrator.
:01:53. > :01:59.In many ways this animal is a missing link between dinosaurs and
:02:00. > :02:02.crocodiles and shows how some of the features that previously just
:02:03. > :02:06.appeared in dinosaurs actually first evolved. For example, dinosaurs
:02:07. > :02:11.start off as to the dead animals, whereas most of their ancestors seem
:02:12. > :02:18.to be four legate. This shows how the transition between 84-legged
:02:19. > :02:19.crocodile like animal and the two legate dinosaur happened.
:02:20. > :02:22.Studying the teleocrator bones also showed researchers that some
:02:23. > :02:24.dinosaur features evolved much earlier than they'd first thought.
:02:25. > :02:30.Now, what does it take to become a member of an all singing
:02:31. > :02:36.Well, we weren't sure so we sent our reporter Whitney
:02:37. > :02:50.You've probably heard of Justin Bieber, Kanye West, maybe even
:02:51. > :02:55.Taylor Swift. What about Kidz Bot? There are a huge US band and sour UK
:02:56. > :03:00.version has launched. Why not come down and meet them, I thought.
:03:01. > :03:06.Turning the camera around, how are you all? Good, thank you. I'm so
:03:07. > :03:10.excited to meet you, how did you get into it? Kidz Bot had a nationwide
:03:11. > :03:13.casting call and the four of us went to London to meet the production
:03:14. > :03:21.team and we were lucky enough to be picked. Amazing, I've seen some of
:03:22. > :03:26.your videos on YouTube. How do you feel about the attention you have
:03:27. > :03:32.received? It's nice to see young fans supporting us. If fans want to
:03:33. > :03:41.get in, what would you say? Enjoy what you're doing. I'm only a few
:03:42. > :03:46.years older than you all. Do you think I have what it takes to be a
:03:47. > :03:54.part of the UK Kidz Bop. Everybody can. Then teach me sudden moves. I
:03:55. > :03:59.think we will teach you some moves from a certain song. I'm ready, I
:04:00. > :04:02.hope you are ready to. I'm ready for my first dance move. You will punch
:04:03. > :04:13.four times with your right hand into the air. One, two, three. Four, on
:04:14. > :04:15.the fifth on your right leg goes out a bit and then crossed behind you
:04:16. > :04:30.and shoulder slide. # Shout out to my ex, you're really
:04:31. > :04:31.quite the mess. I will leave it to the professionals. Don't think I
:04:32. > :04:34.have what it takes just yet! If you've just eaten your breakfast
:04:35. > :04:37.- then I'd look away now. Because today marks 200
:04:38. > :04:39.years since the first It opened in Paris in France in 1817
:04:40. > :04:44.- and wasn't much more than a rickety wooden cart
:04:45. > :04:46.on a track. That's all from me, Newsround's back
:04:47. > :05:02.right here in about half an hour. My favourite TV show is The
