The crackpot theory claims UFOs came and took some dinosaurs away before the rest were wiped out

Well, that is if you believe a madcap theory from a US "non-profit" organisation, which claims they evolved into intelligent beings that have returned to our planet and can speak English.

Supporters of the US-based Earth defence headquarters believe that several velociraptors, made famous by the Jurassic Park movie series, were rescued from Earth by aliens in space ships before the impact 66 million years ago.

Jo Ann Richards tours UFO conferences trying to convince the audience her husband, who is serving life for murder, was once a special forces agent who attended as a child with his father, a 1961 intergalactic conference about the future of the Earth, and met juvenile raptor aliens, who could speak English, and a string of other ET species.

Amazingly, conference goers pay money to hear the tall-sounding tale at conferences in the UK and Europe.

At a UFO conference in Watford she told of a story about how Richards and his father, Ellis Lloyd Richards Jnr, were both involved in secret research involving aliens.

She added as a young boy in June 1961 her husband had attended a covert conference in a castle in England, involving the “leaders of Earth and hundreds of species of aliens from all over the galaxy”.

Her story, which would defy belief to even the most ardent of alien believers, claimed among the alien species were the raptors, that looked exactly like those seen in the Jurassic Park movies, but who could speak English.

She said: "These originated from the dinosaurs on Earth. Some of them left Earth before the comet came and had occupied another planet."

Mrs Richards also uses the platform to gain support for a campaign that her husband is innocent of the shocking murder he was convicted of planning 1n 1982, and, instead was farmed by the CIA, because he was about to expose the fact that aliens are real.

She claims he was previously covertly involved in secret space programmes involving several alien species, but he was framed by the so-called men in black when he was about to blow the whistle on everything.
