Unexpected morphological variability in the eggshells of the South American caimans Caiman latirostris and Caiman yacare

Scientific Reports, 2023
AbstractEggshell morphology is a valuable indicator of the local conditions within the nests of modern crocodilians and birds. In contrast to these latter, the anatomical structure of the eggshells of most crocodilian species is practically unknown. Here, we provide the first characterization of crocodilian eggshells, using x-ray micro-CT scans.

Caiman Bite [PDF]

Wilderness & Environmental Medicine, 2006
Caiman crocodilus, commonly called the spectacled caiman, is a very widely distributed resident of the western-hemisphere wetlands. Caiman bites to humans can cause trauma and infection. There are few reports of caiman bites; however, there is information about bites by other members of the same family, including Alligator mississippiensis.

Development of the chondrocranium of two caiman species, Caiman latirostris and Caiman yacare [PDF]

Journal of Anatomy, 2019
AbstractLittle is known about the embryonic development and variation of the chondrocranium in Crocodylia and there are no works on any Caiman species. Due to the importance of cranial features in the systematics of this clade, investigating the development of the skull in embryonic stages is essential.

The respiratory mechanics of the yacare caiman (Caiman yacareDaudine) [PDF]

Journal of Experimental Biology, 2018
The structure and function of crocodilian lungs are unique compared to other reptiles. We examine the extent to which this, and the semi-aquatic lifestyle of crocodilians affect their respiratory mechanics. We measured changes in intratracheal pressure in adult and juvenile caiman (Caiman yacare) during static and dynamic lung volume changes ...

Thermoregulation in captive broad-snouted caiman (Caiman latirostris) [PDF]

Zoological Studies, 2014
Crocodilians are ectothermic animals. For this reason, the environmental temperature has substantial effects on their physiology and behavior. The thermoregulatory behavior of these animals involves the selective use of different types of environments. This behavior enables them to reach the temperature level for their metabolic activities.

Allometry of reproduction in broad-snouted caiman (Caiman latirostris) [PDF]

Brazilian Journal of Biology, 2001
In the present study regression equations are established between broad-snouted caiman (Caiman latirostris) captive reproductive females snout-vent length (SVL) and body mass (BM) and the following clutch characteristics: egg mass, egg "length" (maximal diameter), egg "width" (minimal diameter), hatchling BM, hatchling SVL, clutch size (number of eggs),

Nasal soft‐tissue anatomy of Triceratops and other horned dinosaurs

The Anatomical Record, EarlyView.
Abstract Although ceratopsid dinosaurs possess a characteristically hypertrophied narial region, soft‐tissue anatomy associated with such a skeletal structure and their biological significance remain poorly understood. The present study provides the first comprehensive hypothesis on the soft‐tissue anatomy in the ceratopsid rostrum based on the Extant ...

A second species of non‐crocodyliform crocodylomorph from the Late Triassic fissure deposits of southwestern UK: Implications for locomotory ecological diversity in Saltoposuchidae

The Anatomical Record, EarlyView.
Abstract The Late Triassic–Early Jurassic fissures of the Bristol Channel area (southwest England and south Wales) are renowned for their diverse vertebrate faunas. These assemblages have yielded an array of predominantly small‐bodied forms that are crucial to our understanding of the early evolution of several major tetrapod clades.
