As filming for Jurassic World is currently underway, director Colin Trevorrow gave fans a bit of treat via his Twitter account on June 29.

The director teased the first human victim in the image, which features a bloody hand imprint on a mobile veterinary unit truck. Trevorrow's caption is pithy and eerie: "Saturday, 4 AM."

Very recently Trevorrow had teased with another image also using a similar caption.

On June 17, the director captured a shadow of the dinosaur's razor sharp teeth and open jaw, seemingly cast by a street light. He simply captioned it, "Nights." The shadow is a vague impression of the dinosaur head stencil of the logo of the film. The image looks pretty darn eery and is enough to get the nervous excitement going in fans.

In an interview with SlashFilm last month, Trevorrow had also dished on what fans can expect from the dinosaur breed this time around.

It had been reported that a new breed of dinosaurs, which will be created by fusing DNA of various species would be a hybrid of a snake, cuttlefish and T-Rex. The director revealed that while it was true that there will be a new dinosaur, he clarified that it would not be a "mutant freak" as had been suggested in speculative reports.

"We were hoping audiences could discover this on their own, but yes, there will be one new dinosaur created by the park's geneticists. The gaps in her sequence were filled with DNA from other species, much like the genome in the first film was completed with frog DNA," he said. "This creation exists to fulfill a corporate mandate-they want something bigger, louder, with more teeth. And that's what they get."

Jurassic World is being directed by Trevorrow and will star Chris Pratt, Bryce Dallas Howard, Jake Johnson, Omar Sy and Irrfan Khan.

The Jurassic Park films are based on Michael Crichton's series of novels about pre-historic beasts being revived by revolutionary gene technology. Frank Marshall and Pat Crowley are co-producing the film alongside Steven Spielberg, who directed the first two installments in the franchise.

The film will hit theaters on June 12, 2015.
