anomalocaridid flaps (marked)

A filter-feeding lobster as big as a human took the place of whales 480 million years ago, a new fossil find has shown.The 6.5ft (two-metre) prehistoric creature belonged to the family of anomalocaridids that were the early ancestors of modern crustaceans, insects and spiders.At this length it would have been comparable in size to athlete Usain Bolt, actor Liam Hemsworth and former wrestler Hulk Hogan.

But while most of its relatives were shark-like apex predators with circular mouths ringed by sharp teeth, the new species, named Aegirocassis benmoulae, was a gentle giant. THE AEGIROCASSIS BENMOULAE The 6.5ft (two-metre) prehistoric creature belonged to the family of anomalocaridids that were the early ancestors of modern crustaceans, insects and spiders.Like modern-day whales, it filtered seawater to trap tiny particles of food, using spine-covered limbs on its head.Fossils also show that Aegirocassis had pairs of swimming flaps along its body. These were likely to be precursors of the unique double-branched appendages seen in modern crustaceans.  Like modern-day whales, it filtered seawater to trap tiny particles of food, using spine-covered limbs on its head.Modern-day lobsters grow to around 19 inches (50cm) and modern-day whales average at around 79ft (25 metres).  Dr Allison Daley, from Oxford University, who co-led a team studying Aegirocassis writing in the journal Nature, said: This would have been one of the largest animals alive at the time.These animals are filling an ecological role that hadnt previously been filled by any other animal. While filter-feeding is probably one of the oldest ways for animals to find food, previous filter-feeders were smaller, and usually attached to the sea-floor. We have found the oldest example of gigantism in a freely swimming filter-feeder.A. benmoulae was named after the Moroccan fossil hunter who discovered it, Mohamed Ben Moula.The 3D fossil, exposed using tiny needle-like tools to chip away the surrounding rock, is exceptionally well preserved.

The fossils were found in the Fezouata Biota formation region of central Anti-Atlas in Morocco (marked)

Graneros of in

David Moyes Real Sociedad side ended their long wait for an away win in the Primera Division as they triumphed 1-0 at Getafe.Sociedad were the only La Liga side without a win on the road this season going into Mondays clash at the Coliseum Alfonso Perez, but they finally got that monkey off their backs courtesy of Inigo Martinezs second-half header.The Sociedad academy product rose highest to nod home Esteban Graneros accurate free-kick off a post in the 66th minute, although Getafe keeper Vicente Guaita will be disappointed at not being able to stop it.

Moyes men have moved up to 10th in the table Victory takes Sociedad up to 10th, level on 33 points with ninth-placed Espanyol, while Getafe remain 13th.Moyes side, who like Getafe came into this game on the back of two wins and a defeat in their last three matches, saw plenty of ball early on but did little with it.The hosts looked sluggish during the opening exchanges, but they had a penalty appeal turned down in the ninth minute.Pedro Leon cut into the box and just as he looked to get it out of his feet and pull the trigger he was stopped in his tracks by a bumbling challenge from Sociedad centre-back Martinez.Referee Melero Lopez waved away the appeals, but the incident sparked Getafe into life and Quique Flores side should have taken the lead when Alvaro Vazquez beat three defenders and then disappointingly toe-poked straight at Sociedads grateful keeper Geronimo Rulli.Leon came within inches of opening the scoring after 20 minutes when he exquisitely curled onto the bar from the corner of the box.Previous
