I had thought fossil branches and leaves from conifers, gingkos and
other large (or large-ish) trees had been found in Archie's habitat.
Add to that the preservation of large sawflies, which again suggests
large trees or logs.
These plant remains could all be driftwood, and the sawflies could have
been blown in. The plated limestones also preserve remains of
cheirolepidiacean hyperxerophilic cactus-on-steroids conifers that I
don't expect to have grown in the same habitat as a ginkgo.
