List of Primeval episodes

A sighting of a strange creature occurs on the outskirts of the Forest of Dean, leading a small team of scientists and government officials to investigate it. They find a Scutosaurus in the forest and discover a time anomaly that leads to the late Permian period, 250 million years ago. The team soon realise that a Inostrancevia also came through and they must find it before it kills anyone.

After a London Underground cleaner is fatally bitten by some type of giant insect, James Lester (Ben Miller) brings the team together to investigate. They find another anomaly that leads to the late Carboniferous, and a colony of giant arachnids that have come through. Using powerful lights to send the spiders back, the team are then attacked by the true killer, an Arthropleura, which bites and poisons Stephen Hart (James Murray). The race is now on to extract a sample of venom from the giant arthropod to synthesise an antivenom before Stephen dies.

Helen escapes from custody at the Home Office by taking the team to an anomaly that unleashes a flock of dodos. Some these dodos are carrying deadly parasites capable of infecting humans. Unknown to the team, Connor Temple's (Andrew-Lee Potts) friends, Tom (Jake Curran) and Duncan (James Bradshaw), capture one of the dodos, but when Tom is infected by the parasite and goes on a rampage, Cutter and the team must find him before they have a pandemic on their hands.

Helen Cutter returns and informs the team that she has seen a highly evolved predator from the future enter the present day. After dispatching the adult creature, Cutter and Helen decide to take its young back through the anomaly in the Forest of Dean, hoping to locate the anomaly to the future, a decision that proves to be a mistake when the creatures break free. Upon his return to the present Cutter is shocked to discover that Claudia Brown has disappeared and apparently never existed in this world.

As Cutter tries to come to terms with Claudia Brown's disappearance, he struggles to adjust to working with her replacement, the slimy Oliver Leek (Karl Theobald). Meanwhile, a trio of bloodthirsty raptors are rampaging through a shopping mall and the team are called in to deal with the situation. When the team arrives back at the ARC, they are introduced to Jenny Lewis (Lucy Brown), the ARC's new PR officer, and a doppelgänger of Claudia Brown.

Cutter and his team find themselves pursuing giant, carnivorous worms from, the Precambrian that start to appear through an eerie fog in a local office block after emerging through another anomaly. As the team deals with the problem, Cutter becomes preoccupied with the team's new PR executive, Jenny Lewis, whom he is convinced is actually Claudia Brown.

Cutter and the team are kidnapped and held in a military bunker by Oliver Leek, who has plans to be the most powerful man in the world using an army of fearsome predators he has captured from past anomalies, while his partner, Helen, furthers her own nefarious schemes. As the team fight for their survival, Stephen deals with a Silurian scorpion which Leek has unleashed onto a busy beach. Back at the bunker, the team have found a way to stop Leek, but at the cost of Stephen's life.

An exhibition of ancient Egyptian relics comes to the British Museum and an anomaly opens in a mysterious monument called the "Sun Cage". A Pristichampsus, believed in Ancient Egypt to be the goddess Ammut, emerges and proceeds to wreak havoc in London. Cutter, Abby, Jenny and new security chief, Captain Becker (Ben Mansfield), pursue it through the city while Connor and new recruit, Egyptologist Sarah Page (Laila Rouass) try to stop more creatures coming through, and make some interesting discoveries about anomalies in the process. Meanwhile, Lester encounters a new adversary: the devious and ambitious Christine Johnson (Belinda Stewart-Wilson), who is after a strange artifact that Helen has stolen.

Three teenage boys break into a house and a mysterious humanoid creature able to camouflage itself in any environment attacks them. Only one boy manages to escape alive. Fourteen years later, in the present day, Cutter predicts an anomaly will appear in the same house in which the boys were killed. He sends Jenny, Abby and Connor to investigate. However, their efforts are thwarted by the creature and the attentions of detective Danny Quinn (Jason Flemyng), who is investigating his brother's disappearance 14 years before. Meanwhile, Cutter, Becker and Sarah are caught off-guard when Helen's forces attempt to infiltrate the ARC.

An anomaly opens at the West London Hospital, causing a group of Diictodon to emerge. They promptly chew through the power cables, cutting the power to the building. Cutter, Abby, Connor and Becker arrive to investigate and evacuate the building as does journalist Mick Harper (Ramon Tikaram) from Evening News HQ, who wants to get evidence of the creatures to expose to the public. However, they return to find Helen and her Cleaner Replica troops (including a clone of Cutter) have taken over the ARC, so they can interrogate the real Cutter about the artifact. As a bomb blast tears the ARC apart and the team battle for survival, Helen declares that she must stop the ARC'S research from destroying the world at any cost... even if it means killing her husband.

The team have to deal with a herd of Embolotherium from the Eocene. Danny arrives with a mysterious woman called Eve who he first saw in the future; having rescued her from Christine Johnson, they endeavour to save everyone from the stampede. When the anomaly closes, at a campsite, Eve opens another anomaly to return the beasts and are all saved. Upon their return to the ARC, the team are shocked to discover that Eve is Helen Cutter in disguise, who takes Johnson hostage. Holding her at gunpoint, Helen steals the artifact, pushes Johnson through an anomaly to be butchered by future predators, and vows once again to stop the ARC's work from destroying the world. The team decide they must stop Helen before she kills anyone else.

Sarah and Becker investigate an anomaly that re-opens at Johnson's HQ and end up fighting for their lives against Megopterans, while Danny, Abby and Connor hunt for Helen in the future. The trio discover Helen plans to prevent the evolution of mankind in order to save the world, resulting in a chase across a Cretaceous forest and into Pliocene Africa. Danny confronts Helen at the location of the human ancestor, Australopithecus, only to find she has poisoned a small group already. Helen delights in her apparent victory, but a raptor that followed Danny through the anomaly charges at Helen and knocks her off a cliff, killing them both. Having ensured the other hominids have survived, Danny then makes his way back to the anomaly, but it vanishes just before he reaches it.

After a year trapped in the Cretaceous period, Abby and Connor finally return to the present, followed by a giant Spinosaurus, the longest known carnivorous dinosaur. The new ARC team responds. Eventually, the Spinosaurus is returned to the Cretaceous when Connor causes an anomaly to implode, from within it.[12] In a reference to Hannah Spearit's previous career as a member of S Club 7, Don't Stop Movin' plays as a distraction to the Spinosaurus.

Connor and his old friend, Duncan, track an elusive Kaprosuchus to the docks, and find evidence of a fresh kill. After bringing it down by using their EMD weapons, Connor and Abby then win back their places on the team.

Three 19th-century humans come through an anomaly in a theatre, and are followed by deadly "Tree Creepers", arboreal raptor-like dinosaurs. One of the time travellers, Ethan Dobrowski (Jonathan Byrne), is a serial killer and another, Emily Merchant (Ruth Bradley), appeals to Matt Anderson (Ciarán McMenamin) to help catch him. After the team deals with the "Tree Creepers", Matt tells Emily that he is going to help her to track down Ethan.

An anomaly allows a pack of Hyaenodons to make their home in the wine cellar of a stately home, where Jenny Lewis is getting married. The wolf-like creatures eat the wedding planner. Jenny and the team subdue them using medieval weaponry. Meanwhile, Becker narrowly escapes a lethal boobytrap set by Ethan, after Jess Parker (Ruth Kearney) saves him; Lester remotely conducts Jenny's marriage. Gideon's "home" is shown – a blasted desolate world.[17] He finally dies from his illness, and he is then revealed to be Matt's father.

A pair of anomalies opens in a prison, one to the Pliocene allowing a terror bird to attack, and Danny Quinn to return. He meets Ethan and realises that he is his lost younger brother, Patrick Quinn. Matt reveals to Emily that he is from the future, and trying to prevent an apocalypse involving the anomalies. Emily returns to the 19th century. Danny warns the team that Philip Burton was involved with Helen Cutter, then he follows Patrick into the Pliocene. Connor discovers that the incidence of anomalies is increasing, and is potentially dangerous.

After failing to stop Philip and having been pulled through the "New Dawn" anomaly, Connor finds himself in a barren wasteland where future predators are the only obvious life. At "New Dawn", Matt and Abby go through the anomaly to rescue Connor. In the future, Matt, Connor and Abby take shelter in an underground bunker as a vicious storm rages on the surface while back at the ARC, Connor's original anomaly reopens. The anomaly at "New Dawn" starts to cause atmospheric changes to the planet and as chaos breaks loose, Philip realizes Helen Cutter has been using him to achieve her goal of destroying humanity. Matt, Connor and Abby are able to fight off Future Predators and make it back to the present. With their help Philip is able to gain control of "New Dawn" once more and Philip decides to sacrifice himself to destroy the installation with the hope that the anomaly will close. "New Dawn" is destroyed but the giant anomaly continues to grow. Back at the ARC several Future Predators come through Connor's anomaly, leaving Lester and Jess to hunt the beasts alone until the team returns. At the ARC the team join forces to defeat the Future Predators and Connor comes up with a plan to merge his miniature anomaly with the giant one and hopefully close them both. Using a containment device, the team are able to take the miniature anomaly to the "New Dawn" site where Matt drives it into the giant anomaly causing them to implode. Matt survives and the team are reunited and return to duties at the ARC. With everything seemingly back to normal and Connor and Abby going to get married, a new anomaly is detected and as the team head out to the field, Matt comes face to face with a battered version of himself who says: "You have to go back".
