In Catalonia, a "Bear-Dog" Extinct for 15.9 Million Years Resurfaces

Introduction: a discovery that crosses geological time

A hybrid dog-bear animal finally identified

The Catalan Institute of Paleontology Miquel Crusafont confirmed, on July 4, 2026, the discovery of a new extinct species named Paludocyon moyasolai, a predator combining physical traits of a dog and a bear, belonging to the extinct family of amphicyonids. This announcement, the result of two years of thorough research, sheds further light on the little-known history of European fauna during the Miocene.

The animal, roughly the size of a large dog with an estimated weight of 50 to 70 kilograms, lived about 15.9 million years ago in a shallow tropical lagoon, a habitat that has completely disappeared from today's Catalan landscape.

Why this discovery goes beyond mere scientific curiosity

Beyond the curiosity it naturally sparks among the general public, this discovery illustrates the little-known richness of Catalonia's paleontological heritage, a site now gaining international recognition thanks to the patience of researchers who have remained committed to this case for more than three decades.

I confess it plainly: paleontology is not my usual area of expertise, but I find it refreshing to devote a column to a discovery that speaks of neither war nor political crisis, while remaining deeply fascinating on a scientific level.

The Els Casots site, a Catalan geological treasure

A reference site for the European Miocene

The discovery took place at the Els Casots site, located in the municipality of Subirats, in the heart of the Alt Penedès region of Catalonia, a paleontological site already recognized as a major reference for the study of Miocenefauna in Europe.

Fossil richness that extends beyond the bear-dog alone

This site continues, year after year, to yield new fossil discoveries, confirming its status as an exceptional window onto an ecosystem that vanished nearly 16 million years ago, long before the first direct ancestors of the human species appeared on the European continent.

I find it remarkable that a site so modest in geographic size continues, decades after its first exploration, to yield discoveries of such scientific significance. It is a reminder that science often advances through patience rather than isolated, spectacular revelations.

A scientific story dating back to the 1990s

A skull extracted more than thirty years ago

The fossil skull that made this identification possible had in fact been extracted from the Els Casots site as early as the 1990s, well before its true scientific importance was fully understood by the paleontological community of the time.

A decisive re-identification during a doctoral thesis

It was not until 2014, as part of a doctoral thesis devoted to the region's fossil fauna, that this specimen was re-identified as potentially belonging to a species until then unknown to science, opening the way to additional years of rigorous verification.

I think this timeline, from the skull extracted in the 1990s to its definitive confirmation in 2026, beautifully illustrates the timescale proper to serious scientific research, so far removed from the demand for immediacy that dominates our era.

Two years of research to confirm the species

Methodological rigor required before any announcement

After this initial re-identification in 2014, researchers at the Miquel Crusafont Institute devoted two additional years of rigorous work to definitively confirm that this was indeed a new species and not an individual variation within an already catalogued species.

A meticulous anatomical comparison with other amphicyonids

This confirmation work required a meticulous anatomical comparison with other amphicyonid specimens already known to science, a complex taxonomy exercise that explains why the final confirmation came only in 2026, more than a decade after the initial re-identification of the skull.

I believe this methodological rigor, which may seem excessively slow to the general public, is precisely the guarantee of scientific credibility we are entitled to demand before a new species is officially recognized by the international community.

A scientific tribute to a renowned paleontologist

The name Paludocyon moyasolai honors Salvador Moyà-Solà

The scientific name chosen for this new species, Paludocyon moyasolai, directly pays tribute to Catalan paleontologist Salvador Moyà-Solà, a respected figure in Iberian paleontology whose work has significantly contributed to understanding the peninsula's fossil fauna over recent decades.

A scientific tradition that honors its pioneers

This practice of naming a new species in honor of an influential researcher fits within a long tradition of scientificnomenclature, a symbolic way of recognizing the foundational contributions that made possible later generations of paleontologists' discoveries.

I find this tradition of tribute particularly moving: it reminds us that science never advances in isolation, but always on the shoulders of earlier researchers whose patient work, sometimes unrecognized in their lifetime, ends up bearing fruit decades later.

The reconstructed diet of this extinct predator

A mesocarnivore with varied prey

Analyses conducted by the research team suggest that Paludocyon moyasolai occupied an ecological niche as a mesocarnivore, likely feeding on medium-sized prey such as primitive deer species, ancestral bovids, and early forms of wild pigs that populated the region at the time. Tooth-wear patterns examined by the team offer indirect but compelling evidence for this varied diet, since different prey types leave distinct microscopic signatures on dental enamel.

An adaptation to a tropical lagoon environment

This dietary reconstruction comes with a broader understanding of the environment in which this predator evolved, a shallow tropical lagoon whose characteristics likely shaped both its hunting style and its particular physiological adaptations. Sediment layers at the site preserve traces of aquatic plants and small crustaceans, painting a picture of a rich, humid habitat far removed from Catalonia's present-day climate.

I think there is something dizzying about imagining a thriving tropical lagoon on the very spot where today's familiar Mediterranean landscapes of Catalonia now stretch, transformed by millions of years of climatic and geological drift.

The amphicyonid family, long-overlooked predators

A family of extinct carnivores with varied shapes

The amphicyonids, often informally nicknamed "bear-dogs" because of their characteristic hybrid morphology, were a family of extinct predators whose members varied considerably in size, with some species reaching builds comparable to today's bears or large cats. Their fossil record spans several continents, suggesting a once-widespread and ecologically successful lineage before its eventual disappearance.

An initial confusion with larger species

The Catalan specimen had in fact initially been compared to much larger amphicyonids, some weighing up to 200 kilograms, before thorough analysis revealed its true, more modest stature, comparable to that of a large domestic dog today. This kind of downward revision is common in paleontology, where early field impressions often give way to more conservative estimates once laboratory work is complete.

I find this size correction particularly instructive about scientific method: rather than clinging to an initially impressive hypothesis, the researchers were willing to revise their original estimate in light of more precise anatomical data.

The central role of the Catalan Institute of Paleontology

An internationally recognized institution

The Catalan Institute of Paleontology Miquel Crusafont, based near Barcelona, has established itself over the decades as an international reference for the study of Iberian fossil fauna, with research teams active at several major sites across the peninsula.

Often fragile funding for long-term research

This scientific success nonetheless rests on often precarious funding, as fundamental paleontologicalresearch regularly struggles to secure the stable budgetary resources needed to carry out research projects that, like this one, span several decades.

I think this chronic budgetary precariousness of paleontological research deserves to be denounced more firmly. A discovery like this one, which took more than thirty years between the fossil's extraction and its scientific confirmation, would not be possible without a minimum of institutional and financial continuity.

What this discovery contributes to understanding the Miocene

An additional piece in the puzzle of European evolution

Every new species identified at the Els Casots site is an additional piece in reconstructing the complex puzzle of European fauna'sevolution during the Miocene, a pivotal period that saw the emergence of numerous animal lineages, some of which survive, in very different forms, to this day.

A better understanding of vanished ecosystems

This discovery also contributes to a finer understanding of the Mediterranean region's vanished ecosystems, allowing researchers to better model the complex interactions between predators and prey in environments now completely transformed by millions of years of climatic and geological change.

I believe these reconstructions of vanished ecosystems offer a valuable perspective on the resilience and fragility of natural balances, a lesson that resonates in a particular way at a time when our own contemporary biodiversity faces unprecedented pressures.

The media echo of a quiet scientific discovery

Coverage that extends beyond Spain's borders

This discovery, initially reported by Catalan and Spanish media, quickly found an echo beyond national borders, with coverage notably provided by French-language media interested in this scientific curiosity from southern Europe.

Public interest that contrasts with scientific funding

This media enthusiasm, however welcome for the visibility of Catalan paleontologicalresearch, nonetheless contrasts with the persistent modesty of budgets allocated to this kind of fundamental research, a paradox that the institutions involved regularly denounce with little success among public decision-makers.

I find this contrast telling of a larger problem: the general public easily gets excited about a widely covered, spectacular discovery, but that enthusiasm rarely translates into concrete, lasting budgetary support for the research that made it possible.

The next steps of research at this exceptional site

Excavations set to continue in the coming years

Teams from the Catalan Institute of Paleontology plan to continue their excavations at the Els Casots site in the coming years, convinced that this site continues to hold other potentially significant discoveries still buried within its geological strata.

International collaboration envisioned to deepen the study

This future work could come with strengthened collaboration with other European paleontological institutions, a pooling of expertise that would help speed up the analysis of future specimens found at this site, already recognized as a continental reference.

I think this prospect of international collaboration perfectly illustrates what an ideal European scientific research effort should look like: national teams pooling their expertise rather than competing against each other for always-limited resources.

A lesson in humility before the vastness of geological time

Fifteen million years, a scale beyond human comprehension

Contemplating a species extinct for nearly 16 million years invites a form of humility before the vastness of geological time, a scale that far exceeds the usual temporal reference points of human existence, both individual and collective.

A reminder of the fragility of any ecological dominance

This discovery also reminds us that even predators as well adapted to their environment as Paludocyon moyasolai appears to have been in its time eventually disappear in the face of the inexorable transformations of their natural surroundings, a lesson in humility that resonates well beyond the scientific field alone.

I think this lesson in humility deserves collective reflection: no species, however dominant within its ecosystem, is immune to long-term environmental change, a lesson that should feed our contemporary thinking on the fragility of our own ecological position.

The wider context of Iberian paleontological discoveries

Spain, a land rich in Miocene deposits

Beyond the Els Casots site alone, the Iberian Peninsula holds many other Miocene deposits that regularly continue to yield new species to science, confirming Spain's status as one of Europe's richest territories for studying this pivotal geological period.

A well-established national paleontological tradition

This geological richness comes with a national paleontological tradition solidly established over several generations of Spanish researchers, whose work has helped make the Iberian Peninsula a favored destination for paleontologists worldwide who specialize in Miocenefauna.

I think this Spanish paleontological tradition deserves to be better known beyond national borders. It represents a collective European scientific heritage that gets far too little attention compared to other, more widely covered fields of research.

What this discovery means for science education

A valuable teaching tool for Catalan schools

This discovery also offers a valuable teaching tool for schools and museums across the Catalan region, allowing teachers to make a story of evolution that can sometimes seem abstract or distant to younger students both concrete and local.

Scientific outreach that still needs to be built

Despite this clear educational potential, scientificoutreach around discoveries like Paludocyon moyasolai often remains limited to a handful of one-off press articles, without any real long-term strategy for integrating these advances into local school curricula.

I believe this weakness in scientific outreach is a recurring missed opportunity. A discovery as narratively rich as an extinct bear-dog would deserve far more systematic educational use with younger generations.

Conclusion: a discovery that honors scientific patience

The culmination of more than three decades of work

The confirmation of Paludocyon moyasolai as a new extinct species beautifully illustrates the culmination of patient scientific work, begun with the extraction of a simple fossil skull in the 1990s and completed only in 2026 after decades of methodological rigor.

A welcome reminder of the value of the long view

At a time when immediacy often dominates our collective expectations, this Catalan discovery usefully reminds us of the irreplaceable value of taking the long view in producing solid, lasting scientific knowledge, a pace that paleontology, by its very nature, imposes on those who practice it seriously.

I close this column with sincere gratitude toward these anonymous researchers who, without much public recognition or generous funding, keep patiently piecing together the forgotten history of our planet, one fossil at a time.
