Did You Know?
This theropod is known from partial skull remains found in Southern France, providing insightful glimpses into its characteristics and classification among theropods.
The discovery of Arcovenator escotae's fossils occurred in the vicinity of Pourrières, positioned within the Var department of the Provence-Alpes-Côte d'Azur region.
This significant find was made during pre-construction evaluations for paleontological and archaeological significance along the A8 motorway section stretching from Châteauneuf-le-Rouge to Saint-Maximin.
The name of the genus Arcovenator pays homage to its geographical roots, originating from the vicinity of the Arc river basin, coupled with the Latin term 'venator', meaning hunter.
The species descriptor 'escotae' is a gesture of gratitude towards the motorway concession firm, Escota, whose financial support since 2006 has been vital in excavating and exploring this site.
This creature once thrived on what is referred to as the Ibero-Armorican island, an expansive prehistoric landmass that corresponds to present-day regions of France, Spain, and Portugal.
Nestled within the Aix-en-Provence basin, known for its gentle and contained topography, this area stood at roughly 35°N in paleolatitude.
It was flanked by limestone highlands, with the Sainte Victoire and Etoile massifs to the north and south, and the Maure Mountains to the east. Sediments from these elevations would journey along rivers toward a sizable lake, depositing layers of lacustrine, alluvial, and fluvial sediments.
This was the environment that this intriguing dinosaur called home, a warm, somewhat moist climate with distinct seasons.
The tail vertebrae of this captivating species display remarkable similarities to those found in Majungasaurus, albeit with a greater degree of compression from the top down.
The vertebral bodies feature dual-concave joint surfaces and are structurally intermediary, with facets not quite as round as those in Ilokelesia, yet less elliptical than those seen in Rajasaurus, lacking both air-filled cavities and the additional spine-to-spine links known as hyposphene-hypantrum articulations.
The horizontally extended portions of their neural arches, known as transverse processes, are less outwardly angled compared to their counterparts in the Brachyrostra subgroup.
The primary specimen representing this unique dinosaur, which is showcased at the Museum Of Natural History in Aix-en-Provence, was extracted from a singular layer of riverine sandstone.
This specimen comprises a well-connected skull, including parts such as a braincase attached to the right bone above the eye socket, a left cheekbone, a solitary tooth, the front segment of a tail vertebra, along the right shinbone, and a calf bone.
Additionally, other fossils found in proximity, both spatially and stratigraphically, namely two segments from the anterior part of the tail and three teeth, have been attributed to the same species, though they hail from different individual dinosaurs.
The tail vertebrae of this extraordinary creature bear a strong resemblance to those found in Majungasaurus but are more compressed from top to bottom.
Their vertebral bodies feature amphicoelous, or hourglass-shaped, connections, exhibiting characteristics that sit between the round articulations seen in Ilokelesia and the more elliptically formed ones in Rajasaurus.
It lacked any signs of air-filled cavities or additional stabilizing articulations known as hyposphene-hypantrum.
The extended projections from the vertebrae known as the transverse processes in the neural arch are less angled compared to what is observed in members of the Brachyrostra subgroup.
A phylogenetic analysis led by Thierry Tortosa and his team, which incorporates findings from both newly discovered fossils and previously unnamed French abelisaurs, provided insights that contribute to the understanding of this dinosaur's lineage.
The research draws upon earlier published materials and outlines the interrelations within the Abelisauridae as depicted in their proposed cladogram.
Further understanding of the abelisauroids' ancient geographical distribution has emerged, challenging theories that only take into account the landmasses formed from the Mesozoic-era fragmentation of Gondwana.
FAQs
What is the distinctive characteristic found in the skull roof of this dinosaur?
The skull roof of this species features a distinctive identifying characteristic, a midline opening, which may have accommodated the pineal gland, located at the back of a subtle dome shaped by the frontal bones.
These bones exhibit a moderate thickness, comparable to that seen in Aucasaurus, yet not as thick as in Rajasaurus, but thicker than in Rugops.
What are the notable features of its shinbone (tibia) and fibula?
The shinbone (tibia) of this dinosaur, measuring a slim 51 cm (510 mm) in length, features a prominent cnemial crest, a trait common among abelisauroids.
It is noted for its outer upper condyle being more pronounced than the inner one, a subtle forward and upward bend at the top edge of the fibula ridge, a distinct lengthwise ridge near the distal end, and narrowing ankle bones.
The fibula, which is nearly half a meter in length, exhibits characteristic features associated with the ceratosaur group of dinosaurs.
Which theropod family and clade does it belong to?
It belongs to the theropod family, specifically categorized within the Abelisauridae clade under Linnaean systematics. This classification places it closely alongside noasaurids, all of which fall under the larger group of Abelisauroidea.
Furthermore, along with dinosaurs like Limusaurus and Ceratosaurus, it is a part of the Ceratosauria branch. Typical traits that define abelisaurids include their uniquely short yet tall head structure adorned with complex surface textures, comparatively tiny forearms, and robust, well-built back limbs.
What branches of European abelisaurs have been identified within the European Archipelago?
Within what's termed the European Archipelago, two distinct branches of European abelisaurs have been identified: an early, basal group seen in the smaller Albian age Genusaurus and Lower Campanian Tarascosaurus, and a later, more advanced group.
This latter category includes the larger Campanian Period Arcovenator, closely related to both the Madagascan Majungasaurus and the Indian Rajasaurus, under the Majungasaurinae subfamily.
How does phylogenetic analysis relate European abelisaur lineages to other abelisaurids?
The patterns of traits discerned through phylogenetic analysis suggest that these European lineages are not more closely related to each other than they are to other abelisaurids, indicating a more intricate historical tapestry of their movement and distribution.
This points to the possibility of an older lineage having spread by land-based separation, and a more recent lineage likely dispersed across oceans.
These findings support the hypothesis that Africa served as a central stepping stone facilitating the interchange of species between Europe and the regions of India or Madagascar, while also highlighting the isolation of South American abelisaurids.
Dinosaurs such as these hold a profound allure due to their deep-rooted lineage, offering a glimpse into the Earth's vibrant and ever-changing past.
The details surrounding this dinosaur may be wrapped in an enigma, yet with every bone fragment that is excavated, a clearer picture begins to form of these exceptional creatures.
