The function of the exaggerated structures that adorn many fossil vertebrates remains largely unresolved. One recurrent hypothesis is that these elaborated traits had a role in thermoregulation. This orthodoxy persists despite the observation that traits exaggerated to the point of impracticality in extant organisms are almost invariably sexually selected. We use allometric scaling to investigate the role of sexual selection and thermoregulation in the evolution of exaggerated traits of the… 

The nature of allometry in an exaggerated trait: The postocular flange in Platyneuromus Weele (Insecta: Megaloptera)

An ancestral condition of dual incipient ornamentation in Platyneuromus is suggested, with a subsequent departure of size and shape of POF in males, triggered by sexual selection.

Does mutual sexual selection explain the evolution of head crests in pterosaurs and dinosaurs

It is concluded that mutual sexual selection presents a valid hypothesis for the functions of ornithodiran cranial crests and the integration of mutualSexual selection into future studies is critical to the authors' understanding of OrnithodIRan ecology, evolution and particularly questions regarding sexual dimorphism.

Female preference for super-sized male ornaments and its implications for the evolution of ornament allometry

These data appear to be the only experimental evidence from the wild of a female preference function that has been implicitly assumed to drive selection that results in the evolution of positive allometry in male ornamentation.

Recognizing sexual dimorphism in the fossil record: lessons from nonavian dinosaurs

This study revisits prior analyses that purport to find quantitative evidence for sexual dimorphism in nine dinosaur species and presents the first statistical investigation of sexualDimorphism across Dinosauria.

Allometric growth in meiofaunal invertebrates: do all kinorhynchs show homogeneous trends?

Statistically significant results were found in all the trunk segments, meaning that these body units grow proportionally correlated with the body, contrary to the results obtained for the spines.

The ‘species recognition hypothesis’ does not explain the presence and evolution of exaggerated structures in non‐avialan dinosaurs

It is concluded that species recognition was not the evolutionary mechanism most likely to be driving the appearance and persistence of exaggerated structures in non-avialan dinosaurs.

A Comparative Study of the Role of Sex-Specific Condition Dependence in the Evolution of Sexually Dimorphic Traits

A comparative study suggests a common genetic/developmental basis of sexual dimorphism and sex-specific plasticity that evolves across the phylogeny—and that the evolution of size consistently alters scaling relationships and thus contributes to the allometric variation of sexual armaments or ornaments in animals.


It is shown that positive allometry is predicted to evolve under much broader conditions than previously recognized, and on the assumption that mating success is not necessarily zero for males with the lowest trait values.

Canine Evolution in Sabretoothed Carnivores: Natural Selection or Sexual Selection?

Scaling relationships indicate the probable importance of sexual selection in the evolution of the hypertrophied sabretooth anterior dentition.

Empirical evidence suggests that positive allometry may be the exception rather than the rule in sexual traits, that directional sexual selection does not necessarily lead to the evolution of negative allometry, and that many sexual traits exhibit sex differences in allometric intercept rather than slope.

Eye size in geckos: Asymmetry, allometry, sexual dimorphism, and behavioral correlates

Adult eye size varied interspecifically in correlation with parameters of behavioral ecology: eyes were significantly larger in nocturnal than in diurnal species, and significantly smaller in cursorial than in scansorial species.

Quantitative aspects of relative growth and sexual dimorphism in Protoceratops

The Upper Cretaceous Djadochta Formation of Mongolia has yielded a remarkable ontogenetic series of skulls and skeletons of the primitive ceratopsian dinosaur, Protoceratops andrewsi. Twenty-four

Convergent evolution of sexual shape dimorphism in Diptera

Comparisons of phenotypic variation in body shape in true flies suggest that a shared pattern of covariation among traits may have channeled the evolution of sexually dimorphic body elongation in these species, and static allometries may have been shaped by species‐specific selection pressures or genetic architectures.

A review of the literature indicates a substantial lack of empirical evidence for these various mechanisms and highlights the need for experimental studies that specifically address the fitness costs of being large at the ecological, physiological, and genetic levels.


It is shown that male horn length depends on factors proposed to affect the mean mate number per mating male, correlating positively with group size and negatively with male territoriality, which suggests that whereas group size increases the opportunity for sexual selection, territoriality reduces it because territorial males are unable to follow and monopolize female groups as effectively as males in nonterritorial species.

Thermal Regulation in Sail Lizards

The sail of Dimetrodon grandis was the end form of an evolutionary series of pelycosaurs that had tended to develop increasingly large sails, with features strongly suggesting an early attempt at temperature regulation.

New materials of Dimetrodon teutonis (Synapsida: Sphenacodontidae) from the Lower Permian of Germany

Additional specimens of the sphenacodontid synapsid Dimetrodon teutonis. including a maxilla, dorsal vertebrae, scapulocoracoids, a humerus, and partial, articulated hindlimbs that consist of the

A new species of Dimetrodon (Synapsida: Sphenacodontidae) from the Lower Permian of Germany records first occurrence of genus outside of North America

This first record of the sphenacodontid synapsid Dimetrodon outside of North America provides not only additional biological evidence of a continuous Euramerican landmass during the Early Permian, but also the absence of any major physical or biological barrier to faunal interchange of terrestrial vertebrates.
