SUMMARY: The description of the new species Elephas chaniensis Symeonides, Theodorou and
Giannopoulos 2000 was published on 9 December 2000 (Syemonides et al., 2000) for the celebration of the
50th anniversary of the Hellenic Speleological Society. The fossil material was collected in the submerged
cave of Vamos near Chania, Crete on the southeast of Drepanon Cape at the east side of the Souda Gulf. In
this paper we discuss the material collected since the first publication. All available data from the first and
recent collections point to the existence of a large but not continental-sized endemic elephant. The material
allows us to understand the size variation of the new species. The finds were collected by divers. The
submerged cave was open to the air during the last climatic minimum. Today only the upper part of the
main chamber is above sea level. All data point to a Late Pleistocene age. Absolute dates are expected to
be available in time for the Congress.
1. INTRODUCTION
The cave was found by E. Eythimaki, during
underwater fishing. It was filmed by G.
Tzanaki and I. Spanos and was first studied by
the geologist V. Giannopoulos from the
Ministry of Culture, who also discovered the
fossil bones. The collected material was transported
to the Geological Department of Athens
University and was studied by N. Symeonides,
G. Theodorou and V. Giannopoulos. Material is
still collected during periods of field work. The
bones are found at a depth of 1.5 to 4.5 meters,
partly in sandstone and partly covered by calcitic
material. The first publication included
data on elephant bones, and as well as fossil
bones of cervids belonging to Candiacervus sp,
or to the smaller group of De Vos (1979), or
close to the lower limit of his ‘size II’. The elephant
material is attributed to the new endemic
species Elephas chaniensis.
2. THE MATERIAL
The first collection includes more than 40
elephant bones. The first impression was that
we were dealing with a large elephant, larger
than any known specimen from the Rethymno
area. It was crucial to know the size variation of
the Vamos population or a least to have a good
indication. If some bones could be attributed to
a large but not continental-sized elephant then
we had an endemic population. If all bones
were close to the lower – though unknown -
limit of continental Late Pleistocene elephants,
then we could not exclude the possibility that
the newly discovered material could represent
the long undocumented occurrence of E.
antiquus on Crete. Some pieces of unciform,
representing three ontogenetic stages from
large to small adult animals, gave the first very
good indication of the size variation of the population.
The material belonged to a large but
clearly not continental-sized elephant.
After the first publication, the diver and geologist
V. Giannopoulos continued from time to
time to collect and observe the elephants of
Vamos cave. New fossils bones came to light
and a new period for bone collecting is planned
for the summer of 2001. Biometrical investigation
of the new material clearly shows that we
are dealing with the new endemic form previously
described.
3. DISCUSSION AND CONCLUSIONS
It was obvious from the beginning that these
elephants had roamed the Chania area during
the last climatic minimum, 18,000 y. BP.
Possibly they had migrated there earlier during
the episode of lower sea level. It was also clear
that the elephants or their bones could only
have entered the cave at periods when the sea
level was at least 10-20 meters lower than
today. This could alternatively have occurred
shortly before the last marine transgression, a
hypothesis making it possible that their extinction
occurred at the beginning of Holocene.
Questions similar to those concerning the history
and the extinction of the Tilos elephants
are apparent:
- When did these elephants arrived on Crete?
- What is their relation with the other Cretan
species?
- What was the influence of Man and Nature
on their extinction ? We must not forget that the
Tilos elephants, the last European elephants,
became extinct just less than 4000 y. BP
(Theodorou 1986, and references within).
