The timings of the tram tour are 10am-noon, 1pm-3pm, 3pm-5pm, 5pm-7pm. The downside is the trams stop at a limited number of points and run for 2 hours at a time. It will be a shame to spend so little time here. Club this with another option and try to spend more time at the park. Trams inside Ancient City.Taxa: The fossils are mostly soft-bodied organisms such as worms and arthropods, a few centimetres across at most.
