RESUMEN
The present paper deals with the archaeozoological investigation carried out on a horse skeleton discovered in a Late Iron Age La Tène tomb (coded CX 143) in Alba Iulia, Romania. The paper presents all the results of the investigation, with a description of finds, adding a detailed assessment of the dentition with some interesting conclusions on the usage of a horse bit and the possible consequences of this use. The morphological features of the horse indicate a 7-8-year-old male individual, with a recalculated height of 1200-1300 mm. What is also stressed in the investigated sample is the lack of the characteristic pathological lesions typical for horseback riding but showing distinctive elements of bit wear. A comparative perspective over the few findings from the same period is provided to ensure the framing of the identified individual into the much larger historical context.
RESUMEN
The reconstruction of past life based on archaeozoology is a challenging domain that offers a range of valuable details concerning former human and animal populations. Additionally, the ancient era is a source of information for human and veterinary medicine, as well as for other biological sciences. This report highlights a pathological lesion identified during the investigation of a horse skeleton from a pit dated La Tène in Alba County (Romania). The left scapula with lesions was collected from the skeleton of a buried 7-8-year-old male horse. The aforementioned bone underwent gross, radiological, and computerized tomography evaluation. Macroscopically, a collar of supraarticular cancellous hyperostosis was detected, most likely as a consequence of an invasive chronic phlegmonous periarthritis and/or bursitis of the infraspinate muscle following probably a penetrating cutaneous wound in the shoulder region. A suppurative periarthritis\bursitis of the infraspinate muscle situated nearby caused, apparently, supraglenoidian periosteitis responsible for osteophytes and exostoses formation in the neck region of the scapula.
RESUMEN
This paper presents a detailed gross description of all anatomical elements of the humerus in the African green monkey and provides comparative and differential elements on monkey osteology. The osteometric investigation adds value to the gross morphological investigation, adjoining metric data to the gross descriptive data set. An in-depth investigation of the microstructural aspects of the humeral bone tissue is provided, with qualitative and quantitative details and potential for diagnostic applications. Of the gross morphological elements described, several unique features specific to this species include the humeral head shape that presents with distinctive low convexity and caudal placement, the shape of the intertubercular groove, the less developed greater tubercle, and the disposition of the rotator cuff muscle insertion. Furthermore, the overall cranio-lateral curvature of the bone shaft was found to have a distinctive 154-155 degree of angulation of the diaphysis, and the well-developed medial epicondyle was observed with its distinctive medio-caudal retroflexion. The histological investigation was more indicative of a typical non-primate organization of the bone tissue, with laminar vascular and avascular structures combined with the presence of the secondary Haversian system involving a mixture of scattered and dense unorganized secondary osteonal structures. The histomorphometric investigation yielded metrical data for the secondary osteonal structures in terms of area (20,331 ± 5105 µm2), perimeter, and vascular canal area (64,769 ± 257 µm2).
RESUMEN
Otological studies rely on a lot of data drawn from animal studies. A lot of pathological or evolutionary questions may find answers in studies on primates, providing insights into the morphological, pathological, and physiological aspects of systematic biological studies. Our study on auditory ossicles moves from a pure morphological (macroscopic and microscopic) investigation of auditory ossicles to the morphometrical evaluation of several individuals as well as to some interpretative data regarding some functional aspects drawn from these investigations. Particularities from this perspective blend with metric data and point toward comparative elements that might also serve as an important reference in further morphologic and comparative studies.
RESUMEN
The present paper deals with a detailed description of the auditory ossicles in Capra hircus. The paper focuses on the morphological and morphometrical description of the ossicular assembly, formed by malleus, incus and stapes. The malleus (overall length, as average- 8.16 mm) comprises the head of malleus (Caput mallei), a slightly strictured part-neck (Collum mallei) with 3 distinctive processes (lateral, rostral and muscular) (Processus lateralis, Processus rostralis and Processus muscularis) and a handle (Manubrium mallei). The head of malleus has an oval aspect with an obtuse articular surface on its medial surface (Facies articularis). The neck is evident with three bony processes described-the anterior, almost triangular, the muscular one quite reduced and the lateral one which is the most developed one. The manubrium is the longest sector-4.4 mm and appears as a slightly curved piece. The incus presents a body of 1.3 mm and two processes-the short and long crus (Crus breve and Crus longum). The overall shape of the ossicle resembles a biradicular molar. The lenticular process is a continuation of the distal part of the long crus. The stapes-the smallest in size of the three ossicles (2.7 mm), has a head (Caput stapedis), an anterior (Crus rostrale) and a caudal (Crus caudale) arm and a footplate (Basis stapedis). The two processes are slightly different in size and morphology, delimiting the intercrural space that shows the presence of a bony spicule. The footplate (1.6 mm2 area) is ellipsoidal, with an anterior narrower extremity.

SUMMARY: Birds are the most diversified organisms on Earth, with species covering various niches in each major biome, being essential to understand the modern ecosystem. This study concentrates on the diversification of the anatomical structure of the upper digestive tract for 26 species of zoophage-polyphagous birds and the anatomical differences in the digestive system to reveal aspects related to their evolution and diversification. The trophic spectrum of the selected birds includes several categories of food, or, as in the case of strictly carnivorous birds, to a single food category. After performing the dissections, the digestive tract was separated from the carcass and each digestive segment was measured and analysed. In this study, it was demonstrated that the birds' feeding behaviour influence the macroscopic particularities of the digestive system, more visible in the cranial portion (oropharyngeal cavity, esophagus, proventriculus and gizzard), with little descriptive information in the literature. The tongue is poorly developed and immobile in piscivorous birds, while the tongue of insectivorous birds is long and moves considerably away from the tip of the bill. The esophagus was stretchable and presents longitudinal folds on its entire surface in piscivorous species and not extensible in insectivorous birds.
Las aves son los organismos más diversificados de la Tierra, con especies que cubren varios nichos en cada bioma principal, siendo esenciales para comprender el ecosistema moderno. Este estudio se concentra en la diversificación de la estructura anatómica del tracto digestivo superior para 26 especies de aves zoófago-polífagas y las diferencias anatómicas en el sistema digestivo para revelar aspectos relacionados con su evolución y diversificación. El espectro trófico de las aves seleccionadas incluye varias categorías de alimentos o, como en el caso de las aves estrictamente carnívoras, una sola categoría de alimentos. Después de realizar las disecciones, se separó el tracto digestivo de la canal y se midió y analizó cada segmento digestivo. En este estudio se demostró que el comportamiento alimentario de las aves influye en las particularidades macroscópicas del sistema digestivo, más visibles en la porción craneal (cavidad orofaríngea, esófago, proventrículo y molleja), con poca información descriptiva en la literatura. En las aves piscívoras, la lengua está poco desarrollada e inmóvil, mientras que la lengua de las aves insectívoras es larga y se aleja considerablemente de la punta del pico. El esófago era estirable y presentaba pliegues longitudinales en toda su superficie en especies piscívoras y no extensible en aves insectívoras.
