Rusophycus.
Rusophycus size (length, width, and surface area) was consistently positively and significantly correlated with most proxies of vermiform burrow size (width and surface area) after Bonferroni correction, with the exception of burrow length (Table 3). This is not surprising, however, as burrow length is the least reliable proxy for body size in ...
