Dear Robert,

thankyou for the nice reply:

Referring to this and looking a little bit ahead (= the to do list):

1) The DSDP volumes ("Initial Reports", the mentioned DSDP 74) contain
in many cases (not in all), particularly for the pioneer days,
taxonomic sections.

DSDP data are also in many (not in all) cases digitally available.

In case it is an issue, I can, within the next 5-7 days, look this up,
starting with DSDP Vol. 74, some of the appendices might provide the
I am aware that sometimes the DSDP Volume are locked away, particularly
during holiday time, thus it is a polite question.


2) Replication of experiments:

In this case it might be replicable:

I don t know which (possibly East Coast repository) it is: For
this question the primary material might be inspected:
(e.g. inspecting both G. mitra from Leg 74 and "original" G. mitras
from other cores / taxonomic descriptions.


3) Now looking ahead (considerably summarized, addressing your
question" and resulting future perspectives, also for the field in

Many initiatives need faunal/floral lists, ideally counted, at least

The well-known and renowned paleontologists who engaged in the DSDP
do not exist in copy.

Some years ago we had a PhD project (started) to do (formulated
compact) "seismics without filtering" both with the the aim to process
seismic lines and with the aim to apply this to related questions
e.g. (again formulated ultra compact) to process cores destruction-free
with the objective to determine forams semi-automatically (and after
the holotypes exist to determine them automatically, e.g. assessing
high-res paleotemperature time-series from the DSDP/ODP cores
that are in the repositories).

In case it is a matter of interest we can aim at it at a low level and
do the production-testing  then within the community.

I am aware that we have to go well beyond one micrometer in resolution.
I am also aware about the data-quantities that will accumulate.

If we have a restart, first at a low level, e.g. "comparable to a hobby"
we might have in, estimated 6+ years, something that is running.

In case anybody is astonished about above mixing of "seismic lines"
with "core analysis": To get a method running one should do it
with data and wavelengths for which formula exist. If later, when
the method runs, one considers also electromagnetical waves, one has
a framework into which it can be inserted.

We started in 1986 with the objective to reconstruct Neogene
(considering at that time that the forthcoming climate is more likely
a warmer than a colder).
The question is solved when good reconstructions, marine and terrestrial
for the last 10 Ma exist (see IGCP341 and resulting tasks) and
when with a coupled GCM, first 10 ka, then 120 ka, then 400 ka,
then 1.2 Ma then possibly more (at T42 resolution) can be run
such that "all the ticks of the time-series" are met
(first Vostok, then the others).

Right now the emphasis is on a fast CAM/CSM with sometimes
an acceleration of 5000% already reached (more needed, the way how to
achieve this is known, e.g. implementing what is tested also elsewhere).

Progress exists but it is not as far as planned.

If both is done in the future, e.g. also your "experiment question"
addressed, much of the "synonym discussions" will, at least
within the Neogene (in the sense of the new definition) disappear
(based on digital holotypes).

It is a little bit a look ahead. It is of course now within our reach
and once a fast CSM will exist it will be addressed.

cooperation based on data-exchange. It is however - meant as polite
warning - a topic that is difficult to publish as the results will
show up as software and results based on this.
