|
Early metazoan evolution, prior to the emergence of the clade that gave rise to crown taxa, involved a number of innovations. |
|
Most of the rudist species listed by these authors are typical late Albian taxa, but their purported occurrences here require additional study and supportive documentation. |

Of course, concomitant with the rich bauplan diversity of pontoniine and palaemonine taxa, more variation exists than herein illustrated. |
|
Later radiations, such as those of fish in the Silurian and Devonian periods, involved fewer taxa, mainly with very similar body plans. |
|
The cladogram is a tool for visualizing and comparing the evolutionary relationships between taxa. |
|
This means, at times, long and perhaps overly discursive discussions of other taxa. |
|
These movement patterns are distinct to the taxa, separating them. |
|
By the middle of the following Cambrian period, a very diverse fauna is recorded in the Burgess Shale, including some which may represent stem groups of modern taxa. |
|
