4 trending stories you may have missed this week

From a pro-dancer groom's surprise for his ballerina bride to a high school senior being sent home from school for exposing her collarbone, there was no shortage of attention-grabbing stories this week. In case you fell off the grid a bit, here are a few that made waves.

1. Woman carries her unborn twin for 45 years

When 45-year-old Jenny Kavanagh visited doctors for a simple procedure, they discovered an undeveloped unborn twin growing inside her. The twin was discovered when medics spotted a mass growing in Kavanagh's left ovary during an ultrasound.

The discovery contained a face, an eye, a tooth and long black hair just like Kavanagh's.

2. Pro-dancer groom surprises ballerina bride with wedding dance mash-up

Choreographed dances at weddings have become almost as common as the cake. This latest groom nailed the execution of his dance, the surprise and making it go viral.

Kirk Henning, a professional dancer for the Richmond Ballet, surprised his new wife, Valerie with a dance mash-up that included Britney Spears, Bruno Mars and more!

According to the YouTube upload, Valerie is also a ballerina!

3. Girl sent home from school for exposing collarbone

For as long as there have been dress codes, there have been students in protest of them -- but rarely do we see parents getting involved.

43-year-old Stacie Dunn from Versailles, Kentucky, is speaking out against the strict dress code enforced at her daughter's school after her daughter was sent home for a violation.

Woodford County High School deemed the seemingly modest outfit inappropriate because it revealed the young woman's clavicle.

In a Facebook post, Dunn wrote:

"Woodford County High School and the principle have been enforcing a dress code whereas girls cannot show even their collarbones because it may distract their male classmates. This is ridiculous! Parents are being called away from their important jobs and students are missing important class time because they are showing their collarbones! Something needs to change!"

Scott Hawkins, Woodford County Schools superintendent, told Today that the school's dress code policy has existed for more than 10 years. He said:

"Our school administration has been very open with students and parents alike, that if they feel like changes need to be made, they are open to suggestions. It just needs to be measurable so that it can be consistently enforced."

4. Footprints of dinosaurs strolling on the beach found in Germany

Even if you weren't one of those kids who obsessed over dinosaurs, chances are you'll still find this story pretty incredible.

A trail of giant footprints left behind by two 30-ton carnivorous dinosaurs have been discovered on a beach in Germany.

Scientists say the footprints, which each measure four feet across and are 17 inches deep, were made 140 million years ago.

Researchers came upon and excavated their fossilized footprints between 2009 and 2011.

Based on the sizes of the prints, it's believed they were megalosaurus, about the same size as velociraptor.

The scientists note that if the two were on a family outing, it could suggest that dinosaurs of their kind were much more social than currently believed.

Another possibility is that the two visited the area on separate occasions, perhaps years apart.
