:00:00. > :00:10.It's Saturday afternoon, I'm Ayshah, time for your Newsround update.
:00:11. > :00:15.Could this bone be from the world's biggest dinosaur?
:00:16. > :00:20.And: The motorised loo world record attempt.
:00:21. > :00:25.First up, footy fans from all over the country will be getting ready to
:00:26. > :00:29.watch the FA Cup final. In just a couple of hours Arsenal will face
:00:30. > :00:33.Hull City. The Gunners are strong favourites but Hull will be hoping
:00:34. > :00:38.for an upset. Leah's been looking at the two teams' chances.
:00:39. > :00:45.The FA Cup. The oldest, most prestigious, knockout football
:00:46. > :00:53.competition in the world. 737 teams entered the cup. Now only two
:00:54. > :00:57.remain. Hull City and Arsenal. Steve Bruce has guided Hull City to their
:00:58. > :01:03.first ever FA Cup final seeing off Brighton, Sunderland and Sheffield
:01:04. > :01:06.United along the way. Steve Bruce won the FA Cup three times as a
:01:07. > :01:10.player and will be hoping history can repeat itself and the Tigers can
:01:11. > :01:17.claim their first major trophy in 100 years.
:01:18. > :01:21.When we were growing up it was the major thing, the FA Cup, the
:01:22. > :01:26.build-up to it. Everybody enjoys a shock. If you are not an Arsenal
:01:27. > :01:31.supporter everybody will be supporting Hull City.
:01:32. > :01:37.Arsenal have won the competition ten times. But they have not won a
:01:38. > :01:43.single trophy in nine years. Their route to the final has not been
:01:44. > :01:48.easy. They have had to defeat Tottenham, Liverpool, Everton, and
:01:49. > :01:55.Wigan to get to Wembley. We want to finish the season very
:01:56. > :02:12.well. It is the last game of the season in England. It is a big game.
:02:13. > :02:16.Let us enjoy it. It's going to be quite a game and
:02:17. > :02:20.you've been telling us all on the website who you want to win. Najma
:02:21. > :02:26.has loved Arsenal since she was little. Go, Arsenal. Herbie wants
:02:27. > :02:31.Hull to win because he's a fourth generation supporter. Come on, you
:02:32. > :02:34.Tigers. Thanks for those, guys. Emergency services are still
:02:35. > :02:37.fighting wildfires in parts of California in America. There are
:02:38. > :02:42.several fires in the state which have already caused around $20
:02:43. > :02:47.million in damage. Schools and homes have had to be evacuated. The BBC's
:02:48. > :02:53.reporter in California, David Willis, has sent this us report.
:02:54. > :02:58.California is known for its heat, but it has been hotter than normal
:02:59. > :03:04.here in the last week. Temperatures up to 40 Celsius in some places.
:03:05. > :03:10.That, coupled with high winds, have led to more than half a dozen fires
:03:11. > :03:13.burning out of control here. Dozens of buildings have been destroyed and
:03:14. > :03:21.thousands of people have been evacuated. Aircraft have been
:03:22. > :03:25.dropping water on the fires from above. So far they have had little
:03:26. > :03:29.success in controlling these fires and what are called "firenadoes".
:03:30. > :03:33.That's a cross between a fire and a tornado which consists of rapidly
:03:34. > :03:36.spinning columns of flame. Two teenagers have been arrested on
:03:37. > :03:43.suspicion of starting two of the fires. But oficials think that heat
:03:44. > :03:46.and the winds are the main culprits. They are hoping that lower
:03:47. > :03:48.temperatures over the weekend will help them gain a hold of these
:03:49. > :03:52.fires. Now to the discovery of bones from
:03:53. > :03:57.what could be the biggest dinosaur ever. Earlier I spoke to dinosaur
:03:58. > :04:06.expert Bill Sellers to find out how exciting this find is.
:04:07. > :04:12.Look at the leg bone. It is over two metres long. This thing was huge.
:04:13. > :04:19.That is fantastic. What do we know about it so far? We know it is very
:04:20. > :04:24.big. It was a plant eating dinosaur. It had four legs and a long neck.
:04:25. > :04:35.How does it compare to other dinosaurs like Diplodocus? How does
:04:36. > :04:42.it fit in? It is much bigger. This is ten times larger than a
:04:43. > :04:54.Tyrannosaurus rex. How important is this discovery? It is very
:04:55. > :04:57.important. We have not found lots of bones, but here we have bones from
:04:58. > :05:04.seven different individuals. That will tell as a huge amount about the
:05:05. > :05:11.dinosaur. What name will it have? It will have a cool name. It will take
:05:12. > :05:16.a year before we do that. These bones are enormous. They have to be
:05:17. > :05:27.taken off to the laboratory and cleaned up and analysed. Then we
:05:28. > :05:30.will name it. Giants to gymnasts now and
:05:31. > :05:33.14-year-old Ellie Downie has made British gymnastics history. She's
:05:34. > :05:36.the first British woman to win a European junior all-around medal,
:05:37. > :05:39.where your score is added up after competing on four separate apparatus
:05:40. > :05:42.- the beam, uneven bars, floor and vault. Ellie took junior bronze in
:05:43. > :05:45.the competition being held in Sofia, Bulgaria.
:05:46. > :05:47.Finally - could this be a world record-breaking toilet? Trevor and
:05:48. > :05:51.Shaun from Brighouse in Yorkshire certainly hope so. Today they're
:05:52. > :05:54.making an attempt at the land speed record for a motorised loo. But
:05:55. > :05:57.they'll have to beat this lady first. Canadian Jolene Van Vugt is
:05:58. > :06:00.currently the fastest person on a toilet.
:06:01. > :06:02.That's all from me. Newsround's back tomorrow.
