a possible red alga from the Burgess shale. It consists of a main stem about 1 cm across, with the longest recovered fossil 6 cm in length. Branches of a similar diameter emerge from the side of the main branch, then rapidly bifurcate to much finer widths. This genus is the rarest rhodophyte from the shale.

As a result, paleontologists and other fossil hunters must often rely on trace fossils, microfossils, or chemofossil residue when scouting for these prehistoric creatures. Hard- bodied and large invertebrates are much more commonly preserved; typically as sizeable macrofossils .
Named Gondwanax paraisensis, the four-legged reptile species was roughly the size of a small dog with a long tail, or about 1 meter (39 inches) long and weighing between 3 and 6 kg (7 to 13 pounds ...
Plant macrofossils include leaf, needle, cone, and stem debris; and can be used to identify types of plants formerly growing in the area. Such botanical macrofossil data provide a valuable complement to pollen and faunal data that can be used to reconstruct the prehistoric terrestrial environment.
Skeletal fragments: this type of limestone texture can be found as whole micro-fossils, whole large fossils or broken up fragments of larger fossils. This is the most common texture. The kinds of skeletal particles present depend upon the age of the rock and the paleoenvironmental conditions from the time they were deposited.
Tree remains that have undergone petrifaction, as seen in Petrified Forest National Park. In geology, petrification (from Ancient Greek πέτρα (pétra) 'rock, stone') is the process by which organic material becomes a fossil through the replacement of the original material and the filling of the original pore spaces with minerals.
