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.


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.
