AMBARES is the acronym of
“Ambares de España” (Ambers from Spain), a
project chiefly funded by the Spanish
Ministry of Economy and Competitiveness. AMBARES is formed by an international group
of geologists and biologists aimed to study
Early Cretaceous amber from Spain (~115 mya)
under a multidisciplinary approach, as well
as other ambers of different ages worldwide.
The team is not only working on amber but
also on other paleobiological fields.
Although this website is focused on Spanish
amber, you can also find works carried out
by the AMBARES researchers, like published
papers, spotlights on paleoentomology, and
congress participations.

CRE: CRETACEOUS RESIN EVENT
Funding of the Cretaceous
Resin Event (CRE) project (CGL2017-84419:
"Cretaceous Resin Event: Global bioevent of
massive resin production at the initial
diversification of modern forest
ecosystems") allowed to give continuity to
the study of Cretaceous ambers until 2021,
extending the research to the western margin
of the Tethys and the Proto-Atlantic
regions. This new project presents a similar
structure to the AMBERIA project in that it
also represents a coordinated effort between
two teams managed from the University of
Barcelona (UB) and the Geological and Mining
Institute of Spain (IGME), directed by Drs.
Xavier Delclòs and Eduardo Barrón,
respectively. The project is composed by 16
Spanish and 15 foreign researches, the
latter from France, Germany, Czech Republic,
Poland, Italy, Lebanon, the United States,
Brazil, and Ecuador.
The main goal of the CRE
project is to test that, during the
Cretaceous, the most important event of
massive resin production in the history of
the Earth took place. This event, apparently
global and continuous in nature, took place
from the Barremian to the Turonian
throughout around 39 Ma. If the existence of
this paleoevent is confirmed, it will be
possible to promote a systematic and
multidisciplinary research on it under a
new, better contextualized perspective,
gaining knowledge on its origin and
implications. |
The hypotheses that we
will test are: (1) the CRE was a single
event over a long period of time in which
the same resin-producing gymnosperm lineage
was involved, (2) this event had a global
character and entailed the presence of amber
deposits in both Hemispheres, (3) during the
CRE time interval, the resin-producing
gymnosperm lineage had its own ecological
association of organisms, which can be
approximated by studying the Spanish amber
and others worldwide, (4) irrespective of
the gymnosperm lineage that produced the
resin, the CRE was conditioned by more than
one abiotic factor during the Cretaceous. |
|
In the last months of the
project, an international meeting on the CRE
will be celebrated at the Geological and
Mining Museum, Madrid. The attendees will
expose their research so that all the
gathered data can be integrated, aiming to
formally define the Cretaceous Resin Event. |
