The paleontological exhibition will have hundreds of fossils of different time periods and different species available for the visitors to touch and compare with the information provided by the zoo. Professionals in the community have donated their time and expertise to make sure the exhibition reaches its goal to educate and unite parents with their children on common activities.

Visitors to the Texas Zoo will soon be able to dig up some history at the zoo's new archeological dig site.

The hands-on exhibit features fossils from The Cretaceous Period, which took place 65.5 million to 145.5 million years ago, to the Quaternary Period, which stems from 2.58 million years ago to present day.

The dig site, which is housed in the Animal Kingdom Building, is expected to open to the public on Saturday.

"There's now more to do at the zoo, which is what we all have been trying to accomplish," said Andrea Blomberg, executive director at the Zoo. "It's educational play."

The exhibit, which has been in the works since August, includes hundreds of fossils ranging from rocks and Texas Hearts to alligators jaws and fish.

Zoo visitors will be able to use tools to uncover the fossils, which have been embedded in sand, and match them to pictures so diggers know exactly what kind of fossil they have found.

"I think it will be an incredible opportunity for an adult of any age. They can get down on their knees with the kids and play," said Blomberg. "It profoundly increases our educational contributions."

The fossils came from both the Texas Zoo's supply and donations, and the majority of the fossils are native to Texas.

Blomberg said the zoo received an additional $1,500 in donations to cover materials needed to put the exhibit together.

Future plans for the exhibit include creating a timeline around the exhibit's perimeter that will detail the time periods from which the fossils came.

Victorians were excited about the educational and fun opportunities the new exhibit brings.

"A project like this helps bring the zoo into the history of the area," said Larry Henneke, a master naturalist with the Mid-Coast Chapter of the Texas Master Naturalists. "When people come to see the animals, they can also have an appreciation of what things were like before man and how man impacts nature."

Texas Zoo animal keeper Arianna Ramirez, 23, expressed similar sentiments.

"I get to know which era things came from and information I didn't know before," Ramirez said. "I like hands-on stuff, too."
