the departures hall. apparently this happened around 8am local time. we're not sure at this stage what has caused these explosions to have, and we're hearing that the rail traffic to the airport has been suspended. as we get more on this, we shall update you, of course.

isaac newton. impress, yes, but we're here for bones that are older 155 million years older. we're hoo here for dinasaur. we're calling him little al if you're thinking castles and kings, think again. >> we're going to start at 150,000 pounds techknow has travelled here to attend an auction of a very unusual piece. meet al. the juvenile alisaurus. there it is. that is amazing. how old is this? >> this is about 155/160 million

years these men are two key players behind what will be a true techknow adventure. he is the curator of this action and the owner of the auction house. what stands out to you, what makes this so unique? >> first of all, it's a juvenile alisaurus. it is rare and unique thing. this is the best example of a juvenile one. >> you can see the teeth, they're very sharp. they're designed for grabbing on and not lesing go. these are for cutting and slicing between 300,000 and 500,000 british pounds >> if you walk in to a dinner party and see that, you will

say, god, what is that is there an appeal for this? >> they're iconic, aren't they there's something new in l.a. dinosaurs are iconic. 1.2 million people came here to see this last year. >> introducing the tr echl x this isn't business as usual. this is the business of bones. you did get a phone call earlier >> yes an interested buyer? >> yes. a buyer who is private, not the museum. he wanted to know the exact size of it the business of bones has been booming since 1997 when chicago's field museum spent 7.6 million dollars on a

t-rex named sue. dinosaurs replacing many things. >> owning an rembrandt in art, there it is for the past week our lives have been on this specimen. so why sell natural history? >> well, why not? why sell art? why sell clocks? >> we love it as art a juvenile dinosaur has advantages at 9 feet long and three feet high it can fit in your home if you have the right-sized home >> i think he wants to display it in his house as a kind of, if you like, trophy, but i wouldn't like to say he is a trophy hunter here at the museum we are used to seeing things like

dinosau dinosaurs, but now private collectors are spending a lot of money to have them in their home. what do you think about that? >> that is a cost to science this is the curator here and he discovered this guy, thomas the t-rex museum? >> yes. i think a dinosaur, especially one that is rare, should belong in a museum the bad lands of montana, is where the dinosaur was discovered. digs like this happen every summer. what they find ends up in their collection. this is what field work looks like >>

>> you can see the woken here into green museums and scientists are not the only ones who organise excavations. the man in charge of this one is raymond. what can you tell me about raymond, the dinosaur hunter. >> he is a qualified geologyist who has been obsessed with fossils. he knows the subject inside out this is the great debate, are science. >> collectors are after the fossil and not much after the context in which the fossil is found. it's really the context that gives you a lot of critical information what would you say to scientists who are concerned about what would happen

tomorrow? individual? >> i would say grow up, wake up and realise that this is the real world meanwhile, inside the auction house offices, the clock is ticking. tomorrow is the big day. we're about 24 hours away from the auction. how are you feeling? >> we're feeling quite confident. you never know until what happens on the day. what happens on the day is what happens it looks like the next chapter of this specimen's 150 million years of history will just have to wrat to be written this-- wait to be written it could end up? >> anywhere in the world where would you like to see it? >> i would like it to go to a museum, but i don't care if it doesn't coming up, auction day. we're just hours away from this thing happening.

>> my fingers and toes are crossed. everything i can cross is crossed we will be soon. we want to hear what you think about these stories. join the conversation by following us on

november 25 2015. good morning. today is the day. auction day. quivering in anticipation. are you all ready getting calls? >> yes the latest chapter in the story that dates back to the lake begin. >> good morning we're just hours away from this thing happening. how are you feeling? >> nervous but i'm trying to

control it you've got hopes? >> everything is crossed this action is full of some pretty amazing exotic things. we've got an hippo skull from africa, some macaws from south africa, but what has everybody is talking about is 150 million years old juvenile dinosaur. today is action day. you must be pretty? >> yes. i'm waiting for tv crews, bbc and itn coming hours attracting international attention. it is now mid-morning. just a few hours before the sale. nerves are getting frayed. morning? >> yes, i've just taken three any last-minute things?

>> several cups of tea an stay calm independent? >> yes ? >> yes the phones will be busy. the question remains will the specimen sell or even reveal a record? the crowd lookss a bit thing, and there are concerns about the quality and authenticity. there are a lot of bones in this thing. how do you know they all come from the same dinosaur? >> we know that because we know where it was excavated and exactly where it was excavated. >> also because it's a juvenile. they are so rare, two

being in the same area would be difficult to imagine it raises the stakes for science and the bidding price if it is real this is one of two in the world. where is most of the interest coming from? >> we've had interest from several museums and we've had interest from a couple of private collectors. whether any of that interest will transfer into bids, i don't know. i imagine it will, but i don't know. >> reporter: the dinosaur is only nine feet in length. museums like to go big, so that could mean this dinosaur would have a better chance of going to a private collector. >> so we stat lot one right now the auction is just starting the auctioneer is calling it out, the phones are ringing. we've got people bidding in the audience. it is on. >> it is with me

seated into the middle of the awedor curator-- audience curator elloll fuller and one-- errol fuller and one on the phone. there are 200 auctions are being auctioned today but not like the dinosaur. there are seven more to go now until the dinosaur is up for auction. auction. >> 2004, 2006 this is it. we're at lot 55. we're about to find what 150 million years of history will bring. >> extremely rare, one of only a couple known in existence and we have called him little al.

we will start at 150,000 pounds. 160. 170. 180. 180,000 pounds. 190 thousand. 190,000 pounds. against you on the phone. 190,000. last chance then on the telephones. 190,000. all at 190,000 pounds. come and talk to us afterwards 190,000 pounds. i think it was lower than hoping. the future remains to be seen for this dinosaur. it only takes a few minutes and then it's over. how do you think it went? >> it was a bit of a blad bath in place-- blood bath there will be no sale today.

the bid was only 190,000 from the private collector. it is below the reserve price or the owner's minimum asking pryings >> it means you're more aligned on a function of uber wealthy people and you're entirely dependentant on whether they want to play they did not sell but the story doesn't end here, right >> absolutely. now i've already been on the phone to a couple of people who are interested in buying it. it may well be we end up selling it more than we needed to. it is a great shame we didn't sell it in the auction the first time around interested? >> two people. it may well be that i end up talking to more the story doesn't end here in london. we're off to copenhagen to share another dinosaur

that was auctioned.

tell us more about the investigation, what sort of concerns there are about those

returning to pick up where others have left off. >> there is a great concern there. a lot - one thing i have to say that has been particularly interesting is the way in which we noticed that on monday that the prosecutors gave very little information at their news conference. i have been following, really, the story of attacks against civil yarns in france, in particular, for more than a year, and we've always noticed that the french prosecutor gives a lot of detailed quality information during his briefings. on monday he said almost nothing. that there been a fear. there has been a criticism that leaps from police officers to journalists have given away details. for example, there was a leak, a fingerprint of salah abdeslam at an apart
