The contents of a special issue of Quaternary International (QI), consisting of 13 articles and contributions by 45 authors (25 from abroad), was recently presented to Dr James Simpson Brink. The papers represent the broad range of topics covered by Dr Brink’s research interests.  

The special issue of QI was initiated to coincide with James Simpson Brink’s 60th birthday after he recently celebrated 35 years of ground-breaking research at the National Museum of Bloemfontein.

Dr Brink is affiliated to the Centre for Environmental Management at the University of the Free State (UFS).

Prof Louis Scott, researcher in the Department of Plant Sciences at the UFS, was the executive guest editor, and was part of a team of three guest editors (Dr Liora Horwitz from the Hebrew University in Jerusalem, and Dr Daryl Codron from the National Museum in Bloemfontein) who worked on this special issue of the journal, QI. 

In honour of a friend and colleague
“Dr Brink made contributions to osteology, Quaternary palaeontology, and archaeozoology, by investigating the environments and mechanisms that drove the evolution of mammal communities of southern Africa,” said the guest editors. 

“By studying the morphology of the endemic black wildebeest he demonstrated how the species evolved in the central interior of South Africa. He pioneered descriptions and dating of faunal assemblages that make up the so-called ‘Cornelian’ and ‘Florisian’ Land Mammal Ages. In this way he reconstructed the long history of environments in which Stone Age occupants survived in the region. The work included the age determination of the cranium with facial bones of an individual who lived at Floribad around 250 000 years ago.

Work enabled more important studies
“Dr Brink contributed more than purely academic insights in that he built and curated the modern mammal and fossil faunal collections of the Florisbad Quaternary Research Station. These collections made it possible for researchers, who came from all over the world, to visit the Free State and focus on spatial and temporal palaeoenvironmental trends. Apart from contributing to the functional diversity of mammalian species, this enabled the investigation of morphological and behavioural variations across populations and communities,” said the editors.

The topics of the papers in this special issue of QI are interdisciplinary and include different methods in archaeology, vertebrate palaeontology and past (or palaeo-) environmental reconstruction. The ages dealt with range from the relatively recent Iron Age to the Oldowan period, which is over a million years old.

According to Prof Scott, with a degree of overlap in the interdisciplinary fields studied, the papers can be arranged into 1) taphonomy and archaeozoology, relating to the processes resulting in the formation and preservation of fossil material in archaeological sites, 2) Stone Age archaeology, dealing with artefacts, stratigraphy and palaeoanthropology, and 3) palaeoecology, that includes palaeontology, isotope studies and palaeoenvironmental reconstructions.

The journal, published by Elsevier, will be distributed worldwide.

Research on locomotion of giraffes valuable for conservation of this species

to galloping.

The meaning of the Arab term Giraffe Camelopardalis is ‘someone who walks fast’. It is precisely this locomotion of their longnecks that encouraged researchers, Dr Francois Deacon and Dr Chris Basu, to study the animals more closely.

Despite the fact that giraffes are such well-known animals, very little research has been done on the manner in which these graceful animals locomote from one place to the next. There are only two known ways of locomotion: the slower lateral walking and the faster galloping. Most animals use these ways of moving forward. It is unknown why giraffes avoid intermediate-speed trotting.

Research of great value to the industry

Research on the manner in which giraffes locomote from one place to the next will assist the industry in understanding aspects such as their anatomy and function, as well as the energy they utilise in locomoting from one place to another. Information on the latter could help researchers understand where giraffes fit into the ecosystem. This data is of great value for large-scale conservation efforts.

Universities working together to collect data

Dr Basu, a veterinarian at the Royal Veterinary College in the UK, has studied the animals at a zoo park in the United Kingdom. He visited the University of the Free State (UFS) in order to expand his fieldwork on the locomotion of giraffes. This study was done in cooperation with Dr Deacon from the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research in South Africa and other African countries.

The fieldwork for the research, which was done in the Woodland Hills Wildlife Estate and the Willem Pretorius Nature Reserve, preceded research on the movement and the forces involved in the locomotion of giraffes. Due to the confined fenced area in the zoo park, it was practically impossible to study the animals at speed. “The study of actions ‘faster than walking’ is crucial for gathering data on, inter alia, the frequency, length, and time associated with each step.


Technology such as drones offers unique
opportunities to study animals like giraffes.



Technology used to ensure accuracyTechnology such as drones offers unique opportunities to study animals like giraffes. Apart from the fact that it is possible to get high-quality video material of giraffes – moving at speed – it is also a very controlled device that ensures the accuracy of data.

It is the first time ever that a study has been done on the locomotion of giraffes with this level of detail.
Research on the study will be published in the Journal of Experimental Biology.

The project was approved by the UFS ethics committee.
