:00:00. > :00:12.Hello, I'm Ayshah with your Newsround update. Coming up: Footy
:00:13. > :00:18.fans gear up for the FA Cup Final. Could this bone be from the world's
:00:19. > :00:20.biggest dinosaur? Emergency services are still
:00:21. > :00:26.fighting wildfires in parts of California in America. There are
:00:27. > :00:31.several fires in the state which have already caused around $20
:00:32. > :00:34.million in damage. Schools and homes have been evacuated and military
:00:35. > :00:37.helicopters have been helping to try and put them out. The BBC's reporter
:00:38. > :00:48.in California, David Willis, has sent us this report.
:00:49. > :00:52.California is known for its heat, but it has been hotter than normal
:00:53. > :00:59.here in the last week. Temperatures up to 40 Celsius in some places.
:01:00. > :01:05.That, coupled with high winds, have led to more than half a dozen fires
:01:06. > :01:08.burning out of control here. Dozens of buildings have been destroyed and
:01:09. > :01:13.thousands of people have been evacuated. A craft have been
:01:14. > :01:29.dropping water on the fires from above. So far they have had little
:01:30. > :01:34.success in controlling these fires. Two teenagers have been arrested on
:01:35. > :01:39.suspicion of starting to offer fires. But experts think that heat
:01:40. > :01:47.and the wins are the worst -- are the main culprits.
:01:48. > :01:51.Now to the discovery of what could be the biggest dinosaur ever. The
:01:52. > :01:54.bones have been found in Argentina and here to talk about how special
:01:55. > :02:02.this find is dinosaur expert Bill Sellers.
:02:03. > :02:08.These are amazing pictures. Look at the leg bone. It is over two metres
:02:09. > :02:15.long. This thing was huge. That is fantastic. What do we know about it
:02:16. > :02:22.so far? We know it is very big. It was a plant eating dinosaur. It had
:02:23. > :02:31.four legs and a long neck. How does it compare to other dinosaurs? How
:02:32. > :02:41.does that fit in? It is much bigger. This is ten times
:02:42. > :02:49.larger than achieve X. -- that a Tyrannosaurus rex.
:02:50. > :02:55.We have not find lots of bones, but here we have bones from seven
:02:56. > :03:01.different individuals. That will tell as a huge amount about the
:03:02. > :03:06.dinosaur. What anime will it have? It will
:03:07. > :03:12.have a cool name. It will take a year before we do that. These bones
:03:13. > :03:19.are enormous. They have two be taken off to the laboratory and cleaned up
:03:20. > :03:25.and described. Then we will mean it. There is more information on that
:03:26. > :03:29.story on our website. Sport now, Arsenal are looking to
:03:30. > :03:33.end a nine year wait for a trophy as they take on Hull City in the FA Cup
:03:34. > :03:39.final. The Gunners are strong favourites but Hull will be hoping
:03:40. > :03:47.to upset their ambitions. Leah's been looking at the two teams ahead
:03:48. > :03:50.of this afternoon's big match. The FA Cup. The oldest most
:03:51. > :03:57.prestigious knockout football competition in the world. 737 teams
:03:58. > :04:07.entered the cap. Now only two remain. Hull city and Arsenal. Steve
:04:08. > :04:12.Bruce has guided Hull City to their first ever FA Cup final. Steve Bruce
:04:13. > :04:16.won the FA Cup three times as a first ever FA Cup final. Steve Bruce
:04:17. > :04:25.player and will be hoping history can repeat itself.
:04:26. > :04:31.When we were growing up it was the major thing. The FA Cup, the
:04:32. > :04:36.build-up to it. Everybody enjoys a shock. If you are not an Arsenal
:04:37. > :04:41.supporter everybody will be supporting Hull City.
:04:42. > :04:48.Arsenal have won the competition ten times. But they have not won a
:04:49. > :04:52.single trophy in nine years. The route to the final has not been
:04:53. > :05:00.easy. They have had to defeat Tottenham, Liverpool, Everton, and
:05:01. > :05:05.Wigan to get to Wembley. We want to finish the season very
:05:06. > :05:14.well. It is the last game of the season in England. It is a big game.

:05:25. > :05:27.But who do you want to win today? Loads of you have been online
:05:28. > :05:31.already. Here's what you had to say: Rosie in Staines says Arsenal all
:05:32. > :05:34.the way! Come on you Gunners! But Jon in London is rooting for Hull -
:05:35. > :05:37.even though he's a Chelsea fan, because Chelsea and Arsenal are big
:05:38. > :05:40.rivals. Finally - could this be a world
:05:41. > :05:47.record-breaking toilet? Trevor and Shaun from Yorkshire certainly hope
:05:48. > :05:50.so. Today they're making an attempt at the land speed record for a
:05:51. > :05:56.motorised loo. But they'll have to beat this lady first. She is
:05:57. > :05:58.currently the fastest person on a toilet, ripping along at 46 miles an
:05:59. > :06:01.hour.
