Hi, I'm Ayshah and this is Newsround.

There's big dino news from over 200 million years ago.

And we say happy 200th birthday to roller coasters.

When this wall fell down at a primary school

have been found to have construction problems.

Most of the buildings have now been repaired,

but some people are calling for the councils in charge to do

more to make sure that new schools are built properly.

To football, and Leicester City still have a chance

to get to the next stage of the Champions League

despite a 1-0 defeat in Spain to Atletico Madrid.

The only goal came after a controversial penalty.

Marc Albrighton's foul looked to be outside the box.

They'll have to overturn that goal in next

Who'd win in a fight - dinosaur or crocodile?

Well, you don't have to chose because researchers have discovered

the fossil of a creature that was a bit of both.

It's helping them find out exactly how crocodiles

There aren't many animals older than a dinosaur right?

Crocodile-like creatures were around way before that,

Now researchers think they've found out

how the crocodiles first evolved into dinosaurs - by studying

a fossil of a creature called a teleocrator.

In many ways this animal is a missing link between dinosaurs and

crocodiles and shows how some of the features that previously just

appeared in dinosaurs actually first evolved. For example, dinosaurs

start off as to the dead animals, whereas most of their ancestors seem

to be four legate. This shows how the transition between 84-legged

crocodile like animal and the two legate dinosaur happened.

Studying the teleocrator bones also showed researchers that some

dinosaur features evolved much earlier than they'd first thought.

Now, what does it take to become a member of an all singing

Well, we weren't sure so we sent our reporter Whitney

You've probably heard of Justin Bieber, Kanye West, maybe even

Taylor Swift. What about Kidz Bot? There are a huge US band and sour UK

version has launched. Why not come down and meet them, I thought.

Turning the camera around, how are you all? Good, thank you. I'm so

excited to meet you, how did you get into it? Kidz Bot had a nationwide

casting call and the four of us went to London to meet the production

team and we were lucky enough to be picked. Amazing, I've seen some of

your videos on YouTube. How do you feel about the attention you have

received? It's nice to see young fans supporting us. If fans want to

get in, what would you say? Enjoy what you're doing. I'm only a few

years older than you all. Do you think I have what it takes to be a

part of the UK Kidz Bop. Everybody can. Then teach me sudden moves. I

think we will teach you some moves from a certain song. I'm ready, I

hope you are ready to. I'm ready for my first dance move. You will punch

four times with your right hand into the air. One, two, three. Four, on

the fifth on your right leg goes out a bit and then crossed behind you

and shoulder slide. # Shout out to my ex, you're really

quite the mess. I will leave it to the professionals. Don't think I

have what it takes just yet! If you've just eaten your breakfast

- then I'd look away now. Because today marks 200

years since the first It opened in Paris in France in 1817

- and wasn't much more than a rickety wooden cart

on a track. That's all from me, Newsround's back

right here in about half an hour. My favourite TV show is The

Dumping Ground because all of them
