| description | A new phymosomatoid species,
Gauthieria pumilio
sp. nov., from lower Campanian (Late Cretaceous) deposits in the vicinity of Hannover, Germany, is described. This species is very close in its overall appearance (i.e. tuberculation and ambulacral plating pattern) to a few other species:
Gauthieria radiata
and the juvenile stages of the Santonian
Gauthieria spatulifera
and the Maastrichtian
Gauthieria princeps
, with which
Gauthieria pumilio
sp. nov. is accordingly closely related. However, it deviates from its relatives by a significantly smaller test diameter. Accordingly it is deviating from the general increase in size during the evolutionary lineage leading from the Turonian
G. radiata
via
G. spatulifera
to the Maastrichtian
G. princeps.
This lineage exemplified Cope's Rule through increasing test size. However,
G. pumilio
sp. nov. challenges this pattern with its dwarfing phenomenon, exhibiting a test diameter |
