I don't know any informed creationists ("YEC" or otherwise) who believe
there has been no change. This is a straw man argument as Gould himself
recognizes.
I maintain that creationists also mean that the group (genus, family, etc)
has remained static for a long time (but much less time than the
evolutionist asserts).

Not necessarily. If that is the extent of change in 200 million years,
that is remarkable. They are clearly similar. The forms from the Permian
and Silurian shown on page 563 of Shrock & Twenhofel (respectively
Paleolimulus and Neolimulus -- the extant genus is Limulus) even more
clearly represent remarkable stasis, as the choice of the genus names
indicates, as well as the obvious similarity of the forms.
