Composition of White Rhinoceros Colostrum and Changes During Early Lactation to Mature Milk. [PDF]

open access: yesZoo Biol
The colostrum phase of white rhinoceros milk ends after 2 days of lactation. The mature milk phase commences after 5 days. The fat content peaks at days 3–4. The Δ9‐desaturase 16 and ‐18 indexes peak at days 2–3. ABSTRACT The proximate composition of milk from seven free‐ranging white rhinoceroses during the first 20 days of lactation is reported with ...

Deep-time preservation of amino acids in mammalian fossil tooth enamel [PDF]

open access: yesCommunications Biology
Tooth enamel, primarily composed of bioapatite, is a promising archive of endogenous organic matter for studying ancient fauna. Despite its low organic content (~1%), protein residues have been identified in teeth up to 24 million years old.

Comparative study of the body proportions in Elephantidae and other large herbivorous mammals. [PDF]

open access: yesJ Anat
In this study, we examine the differences in the body proportions of Elephantidae and other large herbivorous mammals, identify similarities and unique features, and associate these features with the benefits and constraints imposed by their body plan.

Accommodation of Dental Variations During Jaw Growth in Ungulate Mammals. [PDF]

open access: yesJ Exp Zool B Mol Dev Evol
Using geometric morphometrics, we compared the covariation pattern of the dentition and the palate during growth in 23 ungulate species. ABSTRACT The growth of teeth and jaw bones is intimately linked in vertebrates, especially in mammals due to their specialized dentition and limited body growth.

New materials of plesiacerathere (Perissodactyla, Rhinocerotidae) from the late Early Miocene of Northern China [PDF]

open access: yesPeerJ
As a member of Aceratheriinae, the genus Plesiaceratherium in Europe is widely distributed and highly diverse. However, only one species of Plesiaceratherium (i.e., P. gracile) exists in China with a discontinuous distribution range.

A taxonomic review of the genus Rhinoceros with emphasis on the distinction of Eurhinoceros (Perissodactyla, Rhinocerotidae) [PDF]

open access: yesZooKeys
This study examines the ecomorphological characteristics of two Asian rhinoceros species: the critically endangered Sundaic rhinoceros and the vulnerable Indian rhinoceros.

Deciphering the influence of evolutionary legacy and functional constraints on the patella: an example in modern rhinoceroses amongst perissodactyls [PDF]

open access: yesPeerJ
In mammals, the patella is the biggest sesamoid bone of the skeleton and is of crucial importance in posture and locomotion, ensuring the role of a pulley for leg extensors while protecting and stabilizing the knee joint.

Enamel carbon, oxygen, and strontium isotopes reveal limited mobility in an extinct rhinoceros at Ashfall Fossil Beds, Nebraska, USA [PDF]

open access: yesScientific Reports
Ashfall Fossil Beds in Nebraska, USA, was a mid-Miocene (11.86 ± 0.13 Ma) watering-hole that preserved hundreds of herbivores in volcanic ash. The short-legged, barrel-bodied rhinoceros, Teleoceras major (Mammalia; Rhinocerotidae), is abundant at Ashfall

A new late Miocene elasmotheriine rhinoceros from Morocco [PDF]

open access: yesActa Palaeontologica Polonica, 2021
We describe here the first definite representative of the subfamily Elasmotheriinae in North Africa. It comes from the upper Miocene site of Skoura near Ouarzazate, on the southern slope of the Central High Atlas in Morocco.

New material of Epiaceratherium and a new species of Mesaceratherium clear up the phylogeny of early Rhinocerotidae (Perissodactyla) [PDF]

open access: yesRoyal Society Open Science, 2020
Reduction of the anterior dentition (i.e. incisors and canines) is a major adaptative trait of the Rhinocerotidae among Perissodactyla. However, the corresponding evolutionary sequence was lacking a robust phylogenetic frame to support it thus far. Here,
