:00:33. > :00:50.The most powerful man in the world coming to our North Wales School,
:00:51. > :00:56.great. I told who was coming and she said, can I go and see her? We gave
:00:57. > :01:01.them away, but he was on the other side. What an entourage, an
:01:02. > :01:03.incredible amount of vehicles. Like something in a movie.
:01:04. > :01:05.As well as talking about problems overseas,
:01:06. > :01:07.the powerful leaders are also talking about new ways technology
:01:08. > :01:11.As part of that plan, NATO's spending over ?1 billion on drones
:01:12. > :01:20.They can find out lots of information about people,
:01:21. > :01:23.places and they can help soldiers on the ground.
:01:24. > :01:25.Now check out these amazing new pictures of what it's like
:01:26. > :01:30.Scientists behind the mission have been trying
:01:31. > :01:33.to get a close up look at the infamously red surface and there's
:01:34. > :01:38.And scientists want help to find out what this is?
:01:39. > :01:42.This mushroom-shaped sea animal was found off the coast of Australia
:01:43. > :01:45.But scientists still don't know what category of
:01:46. > :01:50.It's one of only four other things in the last 100 years
:01:51. > :01:59.They hope someone will see the pictures and help them.
:02:00. > :02:04.Next, the baby elephant flying high in a cockpit.
:02:05. > :02:07.Gary Roberts came across a herd of elephants that had been killed
:02:08. > :02:12.The nurse and pilot decided to rescue the only survivor -
:02:13. > :02:17.But the only way to get Max to safety was by flying him home
:02:18. > :02:28.The skeleton of the biggest dinosaur to walk on earth, found in
:02:29. > :02:31.South America, is one of the most complete of its size ever found.
:02:32. > :02:35.The huge fossil is from a dreadnoughtus.
:02:36. > :02:38.Scientists studying it say because almost all the bones are
:02:39. > :02:43.there they can find out even more about this amazing creature.
:02:44. > :02:46.It was bigger than seven T-Rexs, weighed more than 13 elephants
:02:47. > :02:51.and had thigh bones as big as a grown man.
:02:52. > :02:57.This dinosaur is part of a bigger family called titanasours,
:02:58. > :03:03.because they were so big, and lived 77 million years ago.
:03:04. > :03:05.Not a lot is known about them but the discovery
:03:06. > :03:08.of this almost complete skeleton is really helping to shed more light
:03:09. > :03:24.Dreadnoughtus gives us a chance to try and incorporate this new data
:03:25. > :03:30.into understanding the way they walked on the way they held their
:03:31. > :03:31.tail and their body proportions and the relative power of their limbs
:03:32. > :03:32.and their tail. It took four years to uncover
:03:33. > :03:35.the bones and now they are being studied in the lab to find out more
:03:36. > :03:38.about the super-massive creature. Scientists have named it
:03:39. > :03:39.dreadnoughtus Although it was not a meat eater,
:03:40. > :03:45.a dinosaur of this size would have Plus it had a long, powerful, tail
:03:46. > :03:53.which is could use to defend itself. At an estimated 65 tons, this dino
:03:54. > :03:59.has set a new record for the biggest animal to walk the Earth, previously
:04:00. > :04:01.the largest known dinosaur weighed And that's not all, the bones
:04:02. > :04:08.of this animal have showed it wasn't fully grown, so it's likely
:04:09. > :04:14.that its parents were even bigger. And joining me is one of
:04:15. > :04:19.the scientists who actually dug up the dreadnoughtus bones, Dr Victoria
:04:20. > :04:30.Egerton from Manchester University. Thank you so much for joining me.
:04:31. > :04:33.You were there, what was it like to find the dinosaur? It was
:04:34. > :04:38.incredible. Most of the bones were bigger than I was and you had some
:04:39. > :04:43.of the bones actually connected together, so part of the tale was
:04:44. > :04:49.articulated into a nice semicircle. How important is it that you found
:04:50. > :04:54.this dinosaur? Really important, it is one of the most complete of this
:04:55. > :05:08.kind ever discovered. It is about 45% complete, so it can tell us more
:05:09. > :05:12.about the bones intact? It is fairly rare, especially for a dinosaur is
:05:13. > :05:16.large, but there wasn't only one, there were two there. What would it
:05:17. > :05:22.have been like all of those years ago when the dinosaur was alive? It
:05:23. > :05:26.would have been living close to Antarctica and one of the cool
:05:27. > :05:33.things about it is it lived in a herd, not on its own, in groups of
:05:34. > :05:38.20 or even 100, or more. That must have been magnetic and tests to see.
:05:39. > :05:43.This is one of the biggest we have seen, but do you think they could be
:05:44. > :05:48.bigger ones out there? There could be, this individual wasn't fully
:05:49. > :05:53.grown yet, so there may be bigger ones to see. It is hard to imagine,
:05:54. > :05:55.if one of its bones were bigger than you, the whole thing, I can't
:05:56. > :05:58.imagine. Thank you for joining me. That's all from me, Newsround's back
:05:59. > :06:02.right here in about half an hour.
