Correlation Structure of the Cheek Teeth Enamel Crown Patterns in the Genus Equus (Mammalia: Equidae): an Analysis by Geometric Morphometrics with Outline Points
Russian J. Theriol. 20(1): 70–81 © RUSSIAN JOURNAL OF THERIOLOGY, 2021 Correlation structure of the cheek teeth enamel crown patterns in the genus Equus (Mammalia: Equidae): an analysis by geometric morphometrics with outline points Igor Ya. Pavlinov*, Natalia N. Spasskаya ABSTRACT. Correlation structure of the cheek teeth enamel crown patterns in the genus Equus was studied by means of geometric morphometrics using outline points as descriptors to reveal the levels of morpholog- ical integration of the toothrow elements. Crown patterns in 34 upper and 31 lower toothrows (260 teeth in total) from 30 horse species were analyzed, the respective sets of 70 to 150 outline points were processed using the elliptic Fourier, principal component, and cluster analyses. The most correlated were shown to be the serial homologous crown elements within premolar and molar toothrow portions and less across the total toothrow. Correlation between occluding upper and lower teeth was shown to be low. Such correlation structure allowed identifying several levels of integration of the cheek teeth crown patterns in the genus Equus. A possibility of considering the serial homologous crown elements as the modules of the evolutionary developmental structure of the equine toothrows was discussed. Certain perspectives of similar studies in the specialized artiodactyles were emphasized. How to cite this article: Pavlinov I.Ya., Spasskаya N.N. 2021.

In contrast, the equine fossil record shows that an extraordinarily richer diversity existed in the past and provides multiple examples of a highly dynamic evolution punctuated by several waves of explosive radiations and extinctions, cross-continental migrations, and local adaptations.

This site was formed in association with a peat bog located on the banks of the old Damas River and has conserved abundant late Pleistocene mammalian fauna and fl ora materials. A date of 11457 ± 140 14C yrs B.P. was obtained from a molar and agrees with our stratigraphic age model. We have identifi ed the fossils as pertaining to the species Equus (Amerhippus) andium, which confi rms its presence in central-south Chile. Furthermore, the recorded geographic location indicate that the metapodial adaptations of the specimens previously described agree with the reconstructed late Pleistocene landscape of Pilauco, dominated by soft volcanic soils and isolated forest patches over large extensions of grasslands. Key words: Equus, Equus (Amerhippus) andium, late Pleistocene, Pilauco.

INTRODUCTION to HORSE EVOLUTION: ANATOMICAL CHARACTERISTICS, CLASSIFICATION, and the STRATIGRAPHIC RECORD © 2008 by Deb Bennett, Ph.D
INTRODUCTION TO HORSE EVOLUTION: ANATOMICAL CHARACTERISTICS, CLASSIFICATION, AND THE STRATIGRAPHIC RECORD © 2008 by Deb Bennett, Ph.D. The impetus for producing this educational article was a telephone conversation with a man whom I normally enjoy. He’s a cowboy, and grew up on a ranch. He’s a kind fellow who has done a good job with not only a lot of horses, but also his kids, who are likewise very fine people. He’s a Christian – a commitment that I respect – and his children were not only raised in their church, but have gone on to attend Bible College. At the same time, this fellow knows that I’m a paleontologist interested in fossil horses. In our recent conversation, at one point he suddenly burst out, “I can’t understand it! Belief in evolution is simply stupid!” I was quite taken aback at his lack of respect for my point of view, because his attitude invalidates my experience and beliefs in a way that I would never impose in return – not to mention that it goes against nearly every piece of advice that St. Paul ever gave. What could possibly cause an otherwise reasonable man to make such a statement so vehemently to someone he knows it is going to offend? Why of course — because the fellow cares about me; he wants my soul to be saved, even at the cost of his own. Why does he think my soul is in danger of damnation? Because he Dr. Deb’s favorite image of “stupid believes that the words he reads in the Bible are to be taken paleontologists” (Moe, Larry, and Curly absolutely literally – no room for metaphorical interpretations, of the Three Stooges) textual criticism, or alternative readings.

However, while the overall picture of equid evolution is well known, the details are surprisingly poorly understood, especially for the later Pliocene and Pleistocene, c. 3 million to 0.01 million years (Ma) ago, and nowhere more so than in the Americas. There is no consensus on the number of equid species or even the number of lineages that existed in these continents. Likewise, the origin of the endemic South American genus Hippidion is unresolved, as is the phylogenetic position of the ‘‘stilt-legged’’ horses of North America.

Buenos Aires, 30-6-2006 ISSN 0002-7014 Ancient feeding, ecology and extinction of Pleistocene horses from the Pampean Region, Argentina Begoña SÁNCHEZ1, José Luis PRADO2 and María Teresa ALBERDI1 Abstract. To reconstruct the diet and habitat preference of fossil horses, we measured the carbon and oxygen isotope composition of 35 bone and tooth samples of Equus (Amerhippus) neogeus Lund, Hippidion principale (Lund), and Hippidion devillei (Gervais) from 10 different Pleistocene localities in the Pampean region (Argentina). To compare the three species by stratigraphic age, we divided the samples into three groups: lower Pleistocene, middle-late Pleistocene and latest Pleistocene. Samples of Hippidion devillei from the lower Pleistocene were more homogeneous, with δ13C val- ues ranging between -11.73 to -9.79‰. These data indicate a diet exclusively dominated by C3 plants. In contrast, Hippidion principale and Equus (Amerhippus) neogeus from middle-late Pleistocene showed a wide range of feeding adap- tations (with a range of δ13C values between -12.05 to -8.08 ‰ in Hippidion and δ13C values between -11.46 to -7.21 ‰ in Equus (Amerhippus)). These data seem to indicate a mixed C3 - C4 diet, while data from the latest Pleistocene suggest 18 a tendency toward an exclusively C3 diet for both species. Furthermore, the results of δ O indicate an increase of ap- proximately 4ºC from the early to latest Pleistocene in this area. Several nutritional hypotheses explaining latest Pleistocene extinctions are based on the assumption that extinct taxa had specialized diets.

FARIÑA, ADA CZERWONOGORA and MARIANA DI GIACOMO Universidad de la República, Laboratorio de Paleobiología, Facultad de Ciencias, Iguá 4225, 11400, Montevideo, Uruguay Manuscript received on November 30, 2012; accepted for publication on June 12, 2013 ABSTRACT The South American Pleistocene mammal fauna includes great-sized animals that have intrigued scientists for over two centuries. Here we intend to update the knowledge on its palaeoecology and provide new evidence regarding two approaches: energetics and population density and relative abundance of fossils per taxa. To determine whether an imbalance exists, population density models were applied to several South American fossil faunas and the results compared to those that best describe the palaeoecology of African faunas. The results on the abundance study for Uruguay and the province of Buenos Aires during the Lujanian stage/age reveal that bulk-feeding ground sloths (Lestodon and Glossotherium) were more represented in the first territory, while the more selective Scelidotherium and Megatherium were more abundant in the second. Although the obtained values were corrected to avoid size-related taphonomic biases, linear regressions of abundance vs. body mass plots did not fit the expected either for first or second consumers. South American Pleistocene faunas behave differently from what models suggest they should.

Nuevo Registro De Equus (Amerhippus) Santaeelenae (Mammalia, Perissodactyla) Del Pozo De Asfalto De Inciarte (Pleistoceno Superior), Estado Zulia, Venezuela
AMEGHINIANA (Rev. Asoc. Paleontol. Argent.) - 43 (3): 529-538. Buenos Aires, 30-9-2006 ISSN 0002-7014 Nuevo registro de Equus (Amerhippus) santaeelenae (Mammalia, Perissodactyla) del pozo de asfalto de Inciarte (Pleistoceno Superior), estado Zulia, Venezuela Ascanio D. RINCÓN R.1, María Teresa ALBERDI2 y José Luis PRADO3 Abstract. NEW RECORD OF EQUUS (AMERHIPPUS) SANTAEELENAE (MAMMALIA, PERISSODACTYLA) FROM THE POZO DE ASFALTO DE INCIARTE SITE (LATE PLEISTOCENE), ZULIA STATE, VENEZUELA. Fossil remains of Equidae from the asphaltic well of Inciarte quarry are described and taxonomically determined. We compared the low- er p3-4 from Inciarte with Equus (Amerhippus) andium, Equus (A.) santaeelenae, E. (A.) insulatus and Equus (A.) neogeus remains from several localities in South America using multivariate analysis. The results of this analysis indicate that Equus (Amerhippus) santaeelenae (Spillmann) is represented in the quarry. Its pa- leoecological implications are discussed. The resource partitioning preference of this species supports the several nutritional hypotheses to explain latest Pleistocene extinctions. Resumen. Los fósiles de Equidae del pozo de asfalto de Inciarte son descritos y determinados taxonómi- camente. Se han comparado los p3-4 inferiores de Inciarte con los de Equus (Amerhippus) andium, Equus (A.) santaeelenae, Equus (A.) insulatus y Equus (A.) neogeus de varias localidades de América del Sur medi- ante análisis multivariante. Los resultados de este análisis indican que la especie Equus (Amerhippus) san- taeelenae (Spillmann) está representada en el yacimiento. Se discuten sus implicaciones paleoecológicas. Algunos autores sugieren que un estrés nutricional, producto de un cambio rápido en las comunidades vegetales, podría ser una de las causas que expliquen la extinción de fines del Pleistoceno.
