Between April 19^th and 23^rd, 2023, Teruel hosted: the 61^st National Philatelic Exhibition and Spanish Championship - EXFILNA 2023 and the 28^th National Exhibition of Youth Philately and Spanish Championship - JUVENIA 2023, as well as the 5^th European Championship of Maximofilia.

One of the exhibits, made by García Díez, José Antonio - "De los primeros pobladores al ser humano" (From the first dwellers to the human), was about animal evolution.

These events were organised by the Spanish Federation (FESOFI) and the Spanish Post (Correos). The exhibition was held under the patronage of the City of Teruel and the cooperation of the Royal Mint, the Aragonese Federation of Philatelic Associations, the Association of Dealers in Philately, Numismatics and Collectables, ANFIL, and EDIFIL publishers.
Three places in Teruel hosted the shows:

• The Bank of Spain hosted the best collections of Master Class and Class of Champions, Traditional Class, Postal History Class and Philatelic Literature Class. In total 37 exhibits on 242 frames, plus Philatelic Literature corner.
• Youth Leisure Center hosted Exfilna-Juvenia and V European Championship of Maximofilia in the Youth category In total 117 exhibits on 415 frames. These Championships included participators from Spain, Brazil, France, Italy, Luxembourg and Romania.
• The Tent of the Plaza La Glorieta hosted the Trade Fair with booths of CORREOS, and FNMT, those of FESOFI, Teruel City Council, ANFL and EDIFIL.

The event was attended by the director of Post Office Philately, Leire Díez Castro, the mayor of Teruel, Emma Buj, the president of the Spanish Federation of Philatelic Societies, José Antonio Arruego and the President of the Aragonese Federation of Philatelic Societies, José Ángel Campo Huerta.
The mayor of Teruel welcomed the attendees and after her speech, the Aragonese and Spanish presidents of the Federation of Philatelic Societies presented the program of Exfilna and Juvenia.
Subsequently, the Director of Philately announced the three stamps that Correos issued for this celebration.

After the commemorative postmark, the attendees, after leaving the consistory, have gone to one of the venues of the Exhibition, the Plaza de la Glorieta, to officially inaugurate EXFILNA-JUVENIA 2023.

A head of Aragosaurus is depicted on the bottom-right side of the self-adhesive stamp - "Teruel region". MiNr.: 5199, Scott: 4169.

The JUVENIA is biennial exhibition, every time it takes place in a different city and for the first time in its history it coincides with the celebration of the EXFILNA. Both exhibitions have 3 locations, but the one dedicated to youth concentrated its activities in the Youth Leisure Center.
Being an exhibition aimed at a younger audience, the aim of Spanish Post was to continue the dinosaur-themed series that in 2015 consisted of the Ankylosaurus, Tyrannosaurus, Triceratops and Diplodocus stamps; and in 2016 the Europelta, Pelecanimimus, Proa and Turiasaurus.

This year, the dinosaur chose was Aragosaurus ischiaticus. The stamp shows a reproduction of what the dinosaur looked like in life. On the tab is an illustration of several of the fossils of this animal.

Aragosaurus was a quadrupedal, herbivorous sauropod dinosaur with a large neck and tail and a small head. The forelimbs of the dinosaur were shorter than the hindlimbs, although not as short as is common in camarasaurids.
Aragosaurus teeth were spatulate in shape and ornamented by longitudinal grooves. Spatulate means that the teeth broaden towards their upper edge into a spoon-like or spatula-like shape.
Its name means "Reptile of Aragon".
Aragosaurus lived during the Upper Jurassic and the Lower Cretaceous (150-140 million years ago) periods and was about 17 meters long and about 25 tonnes in weight, who lived in the environments near the coastline of the Tethys Sea.
Aragosaurus ischiaticus is the first dinosaur discovered in Spain. It was described by Sanz, Buscalioni, Casanovas and Santafé in 1987, based on associated postcranial remains of one individual from the Las Zabacheras site 150m north of the village of Galve in Teruel Province, Aragon, north-eastern Spain - the Villar del Arzobispo Formation.

The Villar del Arzobispo Formation in Spain reveals a high diversity of sauropods living on the Iberian Plate during the Jurassic–Cretaceous transition. To date, diplodocids, turiasaurs, and titanosauriforms have been recovered from Spanish rocks.
Aragosaurus is one of four genera of sauropod recovered from the Villar del Arzobispo Formation in Spain, making the latter an important contributor to understanding of Late Jurassic sauropod diversity alongside the well-known contemporaneous faunas of the African Tendaguru Formation in Tanzania and the North American Morrison Formation (USA).

The fossils material found is inadequate for a formal description, so this taxon needs further documentation and analysis.
Aragosaurus was originally referred to the Camarasauridae and has been provisionally regarded as Eusauropoda incertae sedis by Upchurch at al. in 2004.
The recent research supported by cladistic analysis suggest that Aragosaurus ischiaticus is a basal macronarian that is more closely related to Titanosauriformes than is Camarasaurus.

Macronaria is a clade of sauropod dinosaurs, named after the large diameter of the nasal opening of their skull, known as the external naris (the nostrils), which exceeded the size of the orbit, the skull opening where the eye is located.

In 1934, construction of the old road to Galve led to the discovery of the type locality, initially named ‘La Carretera’.
The first recorded discovery of dinosaur bones was in 1958, when a resident of the village, José María Herrero, reported dinosaur bones from Galve in the local newspaper "Lucha", and then informed the service of excavations of the Diputación Provincial de Teruel.
Dimas Fernández-Galiano and Purificación Atrián, members of IET, visited Galve and located elements of Aragosaurus held in private hands by members of the local population.
After this, Fernández-Galiano returned to Galve in order to excavate new remains from the Las Zabacheras site, including some of the vertebrae and long bones.
All of these elements, including those collected from villagers and the vertebrae and long bones collected later, were housed in the Museo Provincial de Teruel.
Albert F. de Lapparent (1905–1975), from the Institut Catholique, Paris, was the first palaeontologist to suggest that these remains represented a new taxon of sauropod in the scientific journal "Teruel".
Subsequently, in 1982, a team of palaeontologists comprising researchers from the Universidad Autónoma de Madrid and the Instituto de Paleontología de Sabadell (today the Institut Català de Paleontología) informed José María Herrero of the intention to excavate the Las Zabacheras site during the following year; however, it transpired that José María Herrero had already excavated part of the site, so an agreement was made to carry out joint fieldwork.
The resulting material, known as the "J.M. Herrero Collection", enabled the first dinosaur from Spain to be named: Aragosaurus ischiaticus.
The holotype also included the material cited as ‘the sauropod from Las Zabacheras’ by Lapparent (1960), and a tooth was referred from a nearby unnamed locality.
As a result of these events, the holotype specimens are distributed between two collections:
(1) the material recovered by Dimas Fernández-Galiano in the 1950s, which is deposited at the Museo Provincial de Teruel with the acronym ‘IG’;
and (2) the material excavated by J.M. Herrero and the team of author J.L.S. in the 1980s, with acronym ‘ZH’, now in the Museo Paleontológico de Galve.
