0:00:03 > 0:00:06On Newsround this Tuesday.
0:00:06 > 0:00:11The beach that's just for dogs.
0:00:11 > 0:00:20And, the tiny, mighty robots that are strong enough to pull a car!
0:00:23 > 0:00:24Morning, everyone.
0:00:24 > 0:00:26I'm Ricky.
0:00:26 > 0:00:33First up, fossils revealing how T-Rex became a fearsome dinosaur
0:00:34 > 0:00:36have been found in Uzbekistan in Central Asia.
0:00:36 > 0:00:39A new species of Tyrannosaur has been found which shows how quickly
0:00:39 > 0:00:41these dinosaurs evolved from fluffy, horse-sized beasts
0:00:41 > 0:00:42into giant monsters.
0:00:42 > 0:00:44The BBC's science reporter Victoria Gill sent Newsround this
0:00:44 > 0:00:48report.
0:00:48 > 0:00:51So, this is it here, some of the fossils,
0:00:51 > 0:00:53not all of them but once we have here.
0:00:53 > 0:00:55A small box for a dinosaur.
0:00:55 > 0:00:57What we have a are two of the bits.
0:00:57 > 0:00:58Can I hold it?
0:00:58 > 0:00:59Of course.
0:00:59 > 0:01:01There you are.
0:01:01 > 0:01:02Be careful.
0:01:02 > 0:01:0490 million years old.
0:01:04 > 0:01:06Only one of them.
0:01:06 > 0:01:08It's a totally new species of Tyrannosaurus, it is called
0:01:08 > 0:01:12Timurlengia.
0:01:12 > 0:01:15Way back in the Jurassic period, Tyrannosaurus weren't a whole lot
0:01:15 > 0:01:20bigger than me.
0:01:20 > 0:01:24Tyrannosaurus stayed that way human=sized,
0:01:24 > 0:01:27dog-size, little bit bigger, until about this time.
0:01:27 > 0:01:3290 million years ago when they started to very suddenly
0:01:32 > 0:01:37get huge and become dominant, go right to the top of the food chain.
0:01:37 > 0:01:40This is one of those Tyrannosaurus on the cusp of becoming a T-Rex
0:01:40 > 0:01:45type of animal.
0:01:45 > 0:01:47The red sections of this show you how you jigsaw this together,
0:01:47 > 0:01:48what fossil you have.
0:01:48 > 0:01:52This is like a puzzle, and this is what we think the entire
0:01:52 > 0:01:53skeleton would have looked like.
0:01:53 > 0:01:54T-Rex is an evolutionary mystery.
0:01:54 > 0:01:57We don't know much about how a dinosaur was able to become
0:01:57 > 0:02:01so big, such a dominant animal.
0:02:01 > 0:02:05Finding this fossil, a primitive relative of T-Rex,
0:02:05 > 0:02:07gives us some clues to that mystery.
0:02:07 > 0:02:11ROARING
0:02:11 > 0:02:16There's been good news for scientists looking after a probe
0:02:16 > 0:02:18that blasted off yesterday heading for Mars to search
0:02:18 > 0:02:20for signs of life.
0:02:20 > 0:02:23The ExoMars Trace Gas Orbiter has successfully sent a signal back
0:02:23 > 0:02:26to Earth, as it continues on its 500 million kilometre journey
0:02:26 > 0:02:27to the Red Planet.
0:02:27 > 0:02:30The signal was picked up in India, and confirmed that the satellite
0:02:30 > 0:02:31is in good condition.
0:02:31 > 0:02:32To football now.
0:02:32 > 0:02:34And Leicester have kept up their winning ways.
0:02:34 > 0:02:35They beat Newcastle United 1-0
0:02:35 > 0:02:36last night.
0:02:36 > 0:02:39The only goal of the match was from Shinji Okazaki,
0:02:39 > 0:02:41and means The Foxes are now five points clear
0:02:41 > 0:02:43at the top of the Premier League.
0:02:43 > 0:02:45Manager Claudio Ranieri is playing down his side's chance
0:02:45 > 0:02:51of being crowned champions.
0:02:51 > 0:02:53It is open.
0:02:53 > 0:02:56And now we are fighting.
0:02:56 > 0:03:02We are fighting for the Europe.
0:03:02 > 0:03:03And then there
0:03:03 > 0:03:06might be four or five matches, maybe we are fighting
0:03:06 > 0:03:07for the Champions League.
0:03:07 > 0:03:08I think you probably are now.
0:03:08 > 0:03:09Yes.
0:03:09 > 0:03:10Slowly, slowly.
0:03:10 > 0:03:15Match by match.
0:03:15 > 0:03:18Next, to the tiny robots moving full-size cars.
0:03:18 > 0:03:20These microtug robots can pull objects 2,000 times
0:03:20 > 0:03:22heavier than themselves.
0:03:22 > 0:03:28That's the same as one of us pulling a blue whale.
0:03:28 > 0:03:31But, when scientists at Stanford University in the US
0:03:31 > 0:03:34joined them together, they can do this.
0:03:34 > 0:03:37Here they are moving a car weighing 1,800 kilos, 3,000 times
0:03:37 > 0:03:43their combined weight.
0:03:43 > 0:03:46A coin thought to be nearly 2,000 years old has been found
0:03:46 > 0:03:50by a woman out on a walk in Israel in the Middle east.
0:03:50 > 0:03:52The coin, from the year 107AD, shows the image of Augustus,
0:03:52 > 0:03:55the first emperor of the Roman Empire.
0:03:55 > 0:03:58It's only the second of its kind to have been found.
0:03:58 > 0:04:01The coin is thought to have been worth one month's wages
0:04:01 > 0:04:03for a Roman soldier.
0:04:03 > 0:04:09It is important because it is so valuable that it is hard to know
0:04:09 > 0:04:12who would have been walking around with a coin like that in Galilee.
0:04:12 > 0:04:14Coins like that couldn't buy anything.
0:04:14 > 0:04:18It is like a $100 bill or a 500 euros note.
0:04:18 > 0:04:19Sometimes you'd have trouble changing it.
0:04:19 > 0:04:22We don't know who had the coin.
0:04:22 > 0:04:26Whether it was a soldier, which is likely, because these coins
0:04:26 > 0:04:29were given to soldiers as part of their pay.
0:04:29 > 0:04:33Or someone who stole it from a soldier, something like that.
0:04:33 > 0:04:36Next, part of a beach in Argentina in South America has been changed
0:04:36 > 0:04:37into a beach just for dogs.
0:04:37 > 0:04:40The beach has a doggy swimming pool,
0:04:40 > 0:04:43free canine snacks, and a posh food menu for the dogs.
0:04:43 > 0:04:46It means owners now have an area where they can let their pets
0:04:46 > 0:04:48off their leads and let them run around.
0:04:48 > 0:04:50And, finally, happy birthday to Joanne the gorilla who's turned
0:04:50 > 0:04:51two years old.
0:04:51 > 0:04:53Zoo keepers in San Diego in America put up
0:04:53 > 0:04:55decorations in her habitat, and served up treats
0:04:55 > 0:04:56like popcorn and strawberries.
0:04:56 > 0:04:57That's all from me.
0:04:57 > 0:05:00I'll be back with more of the day's top stories at 8.15am.
