Megacheira (from Ancient Greek μέγας (mégas), meaning "great", and χείρ (kheír), meaning "hand", also historically great appendage arthropods) is an extinct class of early Paleozoic predatory arthropods defined by their possession of spined "great appendages". Their taxonomic position is controversial, with studies generally either considering them…
The analysis highlights Art, Taxonomy and Morphology as prominent areas in the source structure around Megacheira.
Source areas are shown by the number of related topics found in each part of the analysis. Use smaller areas too: they can reveal specialized angles and content gaps.
Smaller areas are not necessarily less important. They contain fewer connections in this analysis and can be useful for finding specialized angles or coverage gaps.
