- Collections from
Trinidad:
- Part from H.G. Kugler,
part
from J.B. Saunders, part from K. W. Barr (1963).
-
- H.G. Kugler's Stratigraphic Collection
of Trinidad.
-
- This is a representative collection for the geology and stratigraphic
succession of Trinidad, B.W.I. It was assembled by oil geologist
H.G. Kugler and his collaborators (mainly southern and Central
Trinidad) and by J.B. Saunders for the northern part of Trinidad
while working in Trinidad during the 1920ties through the late
1950ties. Summaries about the history of industrial geological
mapping and biostratigraphy in Trinidad are given in See Saunders,
J.B. and Bolli, H.M. (1985) and Bisson et al. (2002). The collection
represents a systematic collection of rocks, fossils, washed
residues and microfossils from Upper Jurassic to Quaternary formations
exposed in Trinidad. It includes samples from many classical
locations, from where stratigraphic markers and zones have originally
been described and which now serve as the historical reference
to the tropical plankton zonation (see map). Several of the type localities
for formation names or microfossil zones are no longer accessible
today.
-
- Below, a complete record of Trinidad sedimentary formations
is given in 4 sections:
- Section 1 comprises Upper Jurassic to Lower Cretaceous rocks
and formations from Northern Trinidad, collected mainly by John
B. Saunders. A documentation exists in form of maps, labels to
rock specimens and the field-book notes of J.B. Saunders.
-
- Section 2 is a small collection of Ken W. Barr on the Toco
District (NE Trinidad).
-
- Section 3 comprises the Upper Jurassic (Tithonian) through
Maastrichtian rocks and formations, mainly from Central and Southern
Trinidad, and collected by H.G. Kugler and many collaborators.
The documentation exists in form of labels, maps, and reports.
-
- Section 4 includes the Tertiary through Holocene rocks and
formations of Central and Southern Trinidad, collected by H.G.
Kugler and many collaborators and from which materials are kept
for reference purposes at the Natural History Museum in Basel.
The Tertiary formations have been described in great detail in
H.G. Kugler's Treatise on the Geology of
Trinidad (edited by H. M. Bolli and M. Knappertsbusch
in 2004).
-
-
- Status of the collection:
- For the Central and Southern part of Trinidad collections
there is a type-written sample list entitled "Sammlung
von Gesteinen von Trinidad (B.W.I.) from H.G. Kugler, dated
from 1920-1925. It contains information about specimens No. 1
through 784.
- The collection is only in part registered by NMB numbers,
or contains numbers of employees at the Natural History Museum
Basel (for example PJ numbers), which are thoroughly registered
by the museum numbering system. Every information to specimens
is available in form of labels (partly type written, partly hand
written), some with references to the literature. There are large
archive materials of H.G. Kuglers' (all fieldbooks of H.G. Kugler, field
maps, profiles, notes, photographs, reports, letters, etc), that
are kept alongside to these collections (see Legacy of H.G.Kugler, Photo archive of J.B. Saunders and H.G. Kugler
from Trinidad). Much material is referenced to reports
or publications of collaborators of H.G. Kugler. Fossils are
partly determined to species level, although most follows an
outdated taxonomy and only a smaller portion of fossils have
been given modern names. Many of the samples collected by Kugler
are indicated on the various sheets of the Governmental cadastral
sheets of Trinidad, that are deposited at the NMB.
-
- Reference to R.R. Rutsch materials: Especially numerous specimens
in the Kugler collection (and other collns. of the NMB) were
collected by R.F. Rutsch, who documented his observations on
the mollusc fauna from various Tertiary formations from Trinidad
in 13 unpublished reports and in no less than 120 paleontological
letters. Locality lists are given with cross references of NMB
numbers to original RR (Rutsch) localities, as well with cross
references to the collection materials of other collaborators
(K. Rohr, Jooss, H.G. Kugler, Frischknecht, Strasser, and others)
(see unpublished
reports and paleontological letters of R.F. Rutsch, and List
of Rutsch-Locality Numbers from Trinidad, W.I.).
-
- A large compilation of field numbers and information on sampling
locations from early oil geologiests working in the Caribbean
area including Trinidad is available from the CARIBLOC file.

(alongside with the collection):
