What happens to the fossils after they are removed from the tar pit?
Every fossil dug up from the Tar Pits has a characteristic brown hue as a lasting stain from the asphalt. Sometimes specimens can become damaged or cracked during the fossilization process. In the Fossil Lab the team can repair or reconstruct the bone using a transparent, glue-like adhesive (Paraloid B-72).
