The alligator attack that killed Brittany Clark was so vicious that an arm and a hand were nearly completely torn off and her bones had teeth marks, her autopsy found.

Clark, 31, died after the 13-foot beast savaged her during a visit with her boyfriend and roommate to Little Big Econ State Forest in Central Florida on June 28.

Associate Medical Examiner Jenaye L. Mack performed the post-mortem on Clark’s body in Orlando the following morning.

In an autopsy report released Thursday and obtained by The Post, Mack said that Clark’s death was caused by “multiple blunt force injuries of the upper extremities” and the manner of death was an accident.

Mack wrote that Clark had suffered “near complete traumatic amputation of the left arm at the shoulder and near complete traumatic amputation of the right distal forearm.”

She added that teeth marks were found on the left clavicle, left scapula, and ventral left arm.

Following the attack, trappers killed a 13-foot gator found nearby, which officials for the Florida Fish and Wildlife Conservation Commission (FWC) later confirmed as responsible for the deadly attack using DNA.

Officials said Clark’s boyfriend, Chance Allison, desperately tried to wrench her from the reptile’s jaws as it ripped her arms apart.

Allison later described how the gator crept up “out of absolutely nowhere” and grabbed hold of Clark while they were cooling off in the river.

“We were smiling and talking and then it was complete chaos,” said Allison.

The “bad a–”  bulldozer-driver and animal lover used some of her final breaths while bleeding out to ask her beau to look after her German Shepherd dog, who was with them on the hike in Central Florida, Allison said.

“While we were waiting for emergency services to arrive, Brittany just told me to make sure I took care of Hokie,” Allison, 30, told The Post.

“It was one of the last things she said to me,” said the distraught partner, who also brought his Pitbull-mix, Bulma, along for the hiking trip.

Clark was rushed to hospital, but nothing could be done to save her life.

Her roommate, Jayden Hernandez, said she went along for the trip to one of her friend’s favorite spots and “won’t EVER forget every detail of this scene.”

Hernandez wrote on Facebook that the trio had even joked about there being an alligator in the three feet of “murky” water that they were standing in before disaster struck.

Meanwhile, Clark’s dad revealed to The Post how he received a harrowing call from her roommate as his daughter bled out.

“They were trying to keep her alive and waiting for the authorities to show up,” US Navy veteran Robert Clark said.
