Red-flanked duiker (Cephalophus rufilatus). The little slits they have right below their eyes are their preorbital glands, which are seen in many species of artiodactyls and used for scent marking.

Red Flanked Duiker
This species will often follow foraging primates (such as Tantalus monkeys and baboons), feeding on the flowers, fruits, and vegetation that get dropped from the treetops. They are also able to stand upright on their hind legs to reach food that is above their normal reach. Typical of duikers, this species is shy and quickly flees into cover if alarmed. The alarm call is a shrill bark or loud snort.

Pachycephalosaur domes: Function
Welcome back! We last left our heroine (that’s me!) as she gave a brief overview of the history of interpretations of pachycephalosaur domes. We now return to your regularly scheduled program.
However, little discussion was had of the function of the pachycephalosaur dome in this early work, with suggestions limited to the broad category of “armour” (ex: Gilmore, 1924). 
Tumblr media
(Image: A skeletal restoration of Stegoceras validum showing pachycephalosaur anatomy as known in 1924. Outlined parts are inferred from comparison with Hypsilophodon. Image from Gilmore (1924).)
The first worker to propose a functional use of pachycephalosaur domes was Edwin Colbert in 1955, who compared the domes to the cranial “bosses” of artiodactyls and suggested that they may have been used similarly in head-butting battles - here used to mean head-to-head smashing contests -  over mates. 
Galton (1971) thought this was a pretty boss idea, and pointed out that the domes of pachycephalosaurs were made of very thick solid bone. Bone takes a lot of energy to maintain; despite looking like a static, dead rock, it is in fact a living tissue that is constantly remodeling itself (hence why you can repair after a broken bone!). If the domes were just for display, Galton argued that it’d be much more beneficial for them to be hollow. (This would also make them lighter to carry around.)
This still left the suggestion of the dome being used as an anti-predator weapon. Galton argued that this also was unlikely — after all, if something is trying to kill you, why not have a sharply pointed head instead of a dull, rounded one? Finally, Galton pointed out that the neck articulation was rotated to the bottom of the skull, a condition that we’ve seen is extremely rare among animals. He argued that this was an adaptation for transferring stresses away from the brain and into the body after two pachycephalosaurs bonked heads.
Tumblr media
(Image: *Bonk*. <Drawings of pachycephalosaur skulls bonking into each other, with arrows showing his interpretation of how forces would be transferred>. From Galton (1971).)
Sues (1978) agreed that the thickening of the skull functioned to reinforce it for use as a battering ram. In order to see whether it had any structures that indicated special adaptations for bonking heads, he cut a pachycephalosaur dome open and looked inside it.
Modern animals that butt heads with each other are, of course, in danger, because the skull contains the brain, which is a part of the body that you generally don’t like getting sloshed around. A completely solid dome, while very durable, might thus not be the best way to go if you’re bonking into things. This is because it would lead to all forces traveling directly into the brain, without absorbing any of the impact. A more springy dome that keeps its strength but can deform would mean that that stress gets reduced. It’s the same reason why modern cars are designed to crumple to keep you safe. 
So in order to counter that, modern head-butting mammals have hollow areas on their heads that are reinforced on the inside with bony struts. Here’s an example of that in a Cape Buffalo:
Tumblr media
(Photo: The skull of a Cape Buffalo (Syncerus caffer), which has broken open, revealing a complex series of sinuses and body struts under the horns. Source)
 So what did Sues find when he cut open the skulls of pachycephalosaurs? See for yourself:
Tumblr media
(Image: A thin section through the dome of a Stegoceras validus - this section is cut from “ear to ear”, if that helps you imagine it (though note that their ears weren’t quite in the same place as ours; this is just to help clarify what’s being shown here). I’ll describe anatomically what’s going on in the next paragraph. Image from Sues (1978).)
First things first, those big cracks are not anatomical features; so far as I can tell, they are just cracks in the specimen. What we’re really looking at here are the much smaller bony struts and cavities that radiate away from where the brain would be towards the outside of the skull. Sues termed these radiating trabeculae, and argued that they served a similar function to the sinuses in buffalo. They are not nearly as big as the ones in buffalo, but Sues suggested that differences in brain size and structure might have meant that such protection wasn’t as necessary in pachycephalosaurs.
This idea that the pachycephalosaur skull could resist stresses was elaborated on by Snively and Cox (2008), who, using computer models, demonstrated that point stresses applied to higher-domed skulls would diminish rapidly with distance from the point of contact. They found that flat-headed pachycephalosaur skulls would propagate stresses through their structures far more. Based on these results, they predicted a high occurrence of injury to the surface of the dome. 
Tumblr media
(Image: Biomechanical computer models of the flat-headed Homalocephale and the dome-headed Pachycephalosaurus. The former shows high stresses throughout the “dome”, while the latter shows stresses diminishing near the point of contact.)
Their predictions were confirmed by Peterson et al. (2013), who examined domes across pachycephalosaur diversity for evidence of injury. Fully 22% of specimens observed showed injuries to the frontoparietal dome, and 7% of specimens had 6 or more lesions. This is an insanely high frequency of injury, and lends some support to the idea that they were hitting their heads against something. Injuries were concentrated near the peak of the dome, as might be expected were domes used in butting behaviour; all flat-headed specimens examined lacked head injuries. 
Tumblr media
(Image: Six different pachycephalosaur domes, all with surface injuries (indicated with white arrows). Image from Peterson et al (2013).)
Snively and Theodor (2011) offered comparisons to modern head-butting mammals including giraffes, musk oxen, and duikers by examining bone density. Their results showed that pachycephalosaur cranial domes exhibit particularly dense bone superficially but much less dense bone as one moves deeper into the dome, a pattern seen also in head-butting artiodactyls, and suggested that this supports them using their heads to hit things with. 
Tumblr media
(Image: Scans through the skull of Stegoceras, showing higher bone density in red and lower in blue. Higher-density bone is concentrated towards the outside of the dome, with lower-density bone inside. Modified from Snively and Theodor (2011).)
Modern animals that butt heads typically have broad-flat surfaces (as in bighorn sheep) or otherwise branches or structures to maintain contact (as in ibex, for example). Pachycephalosaurs have neither of these, instead having rounded domes; if two ran at each other, it is easy to image how they might glance off each other and injure their necks. Sues (1978) thus argued that the domed shape might indicate flank-butting (in which animals would ram each others’ sides). 
Tumblr media
(Image: Problems with pachycephalosaurs bonking heads. Modern bighorn sheep skulls have wide surfaces of contact, while pachycephalosaurs would have only a very small point on the top of a round dome. Image from Carpenter (1997))
 This was elaborated upon by Carpenter (1997), who noted that the head-butting hypothesis supposes that the skull and vertebral column act in a straight line to transmit forces through the body (rather than into the neck). Carpenter observed that, though no complete neck is known from a pachycephalosaur, the orientation of the back vertebrae and of the socket on the skull necessitate a gently S-curved neck and back, as in most ornithischians. As such a curved neck would transmit stresses diagonally on the spinal column, it risks breaking the neck. Today’s head-butting mammals solve this problem by having tall spines on their neck and back vertebrae, but these are not present in pachycephalosaurs. 
Tumblr media
(Image: Schematic drawing of a pachycephalosaur skeleton, showing S-curved neck and transmission of stress shear-wise to vertebral column. Modified from Carpenter (1997).)
He agreed that flank-butting was a more likely use of pachycephalosaur domes, pointing to similar behaviour in modern African antelope. Finally, Carpenter pointed to the wide ribcage of pachycephalosaurs as possible evidence of thickening the torso to better protect against butting behaviour. 
Tumblr media
(Image: Drawing of two pachycephalosaurs butting each others’ flanks. Modified from Carpenter (1997).)
Goodwin et al (1998) agreed about flank-butting, and also believed that the structure of the dome would not have offered protection against stresses as the trabeculae were not interconnected. Instead, they interpreted the structures instead as artefacts of rapid growth of the dome.
Bony reinforcements of the tail are pretty common in dinosaurs; they are most extensive in the “duck-billed” hadrosaurs, in which the tendons of the back have turned to bone and effectively make the entire back and tail stiff and unable to move. 
Pachycephalosaurs have similar-looking structures on their tails, and Goodwin et al. suggested that the reinforced tail of pachycephalosaurs may have served a role in flank-butting behaviour, offering that it may have been used as a defensive weapon against other pachycephalosaurs.
Tumblr media
(Image: Skeletal drawing of Stegoceras. Note the complex “basket” of bones reinforcing the tail. Image by Scott Hartman @skeletaldrawing​.)
However, the idea of the tail as a defensive weapon was rejected by Brown and Russell (2012). These authors demonstrated that, amazingly, the “basket” of bones reinforcing the tail are not tendons, but instead the divisions between the individual muscle blacks that have turned to bone! This is a condition that’s unknown in any other tetrapod (though it’s present in some fish). Due to the location of the ossifications within the muscles rather than the skin, these authors argued that it would not be useful as a weapon. These authors instead suggested that the the tail served to brace the body in a tripodal stance during flank-butting, an idea first proposed by Maryańska and Osmólska (1974).
The first major objection to be raised against generalised butting behaviour in pachycephalosaurs was by Goodwin and Horner (2004), who sliced into the domes of pachycephalosaur skulls of different ages. Building off of work done by Goodwin et al. (1998), they argued that the “radiating trabeculae” that had been cited by previous authors as being adaptations for reducing strain on the brain are instead temporary features associated with the rapid growth of the skull and disappear as the animal ages, and that the shape of the adult dome was ill-suited for dissipating stress. 
Tumblr media
(Image: Thin sections of two pachycephalosaur domes, the left from a younger individual, the right from an older individual. Stage II (the less dense, spongier bone) is propotionally thicker in the younger individual. Images are not to scale. From Goodwin and Horner (2004).)
The authours instead argued that pachycephalosaur domes functioned as species-recognition characteristics, as they were apparently not sexually dimorphic (to be discused in a future post, which will be linked here).
This idea received criticism for failing to address why animals would evolve such thick and dense structures if they were just for display, and I confess I don’t buy the idea at all. . Lehman (2010) also took issue with the characterisation of the dome histology, concluding that the radial structure of the bone was present even in the most superficial, densest bone zone, albeit with a decreased amount of vascularity; and that the less compact, vascular bone was maintained at least until the individual attained adult size. He further noted that trabecular struts of a form similar to those found in pachycephalosaur frontoparietal domes are strongest against compressional stress along their long axis, consistent with high strength in pachycephalosaur domes. 
Longrich et al (2010) argued that the dome could not possibly have functioned in species recognition, because dome shape is not significantly different between different species — an observation that, to my view, is an extremely convincing argument against the “species recognition” idea. These authors also pointed out that some degree of asymmetry was not uncommon in pachycephalosaur domes, and noted that this is a common trait of featured which have been sexually selected (both in display structures and intra-specific weapons).
This was a bit of a longer post this week, but I wanted to make sure I had a good overview of different proposed functions of the dome. This series will conclude next week with a look into who had the dome, and finally what I think they were doing with it! A link to that will be >here< once it’s up.

I have no knowledge of deers I will classify them all as “deers”. Sure some look different but they are all same ish.
YEAH like of it has 4 legs and antlers it's deer or deer adjacent to me tbh. antelope? yeah sure. giraffe? close enough. heck not even all species of deer have antlers, water deer don't have any at all, just tusks
I do wanna learn the difference between them just for "not mislabeling them"s sake you know but it's VERY HARD when some of them look so similar. the first one is a species of antelope, a red-flanked duiker, and the second is a mouse deer
Tumblr media Tumblr media
how on EARTH are these completely different species im 😭

Bronx Zoo, New York City (No. 38)
African Plains allows visitors to walk past lions, African wild dogs, and Grévy's zebras, and see herds of Thomson's gazelles, lowland nyalas, and slender-horned gazelles sharing their home with lesser kudus, marabou storks, grey crowned cranes, blue cranes, and red-flanked duikers. Hybrid giraffes (Baringo × reticulated giraffe) roam nearby. The exhibit originally opened in 1941 and was the first in the country to allow visitors to view predators and their prey in a naturalistic setting as well as allowing large predators such as lions to be exhibited cage-free. This success was achieved through the creation of a series of deep moats, a set-up which can still be found at the zoo today. The wild dogs, however, can be viewed close-up from a glass-fronted viewing pavilion. The zoo has bred their lions on multiple occasions, including one male and two females born in January 2010 and three males and one female born in August 2013. The zoo, in partnership with the NY Daily News, held a contest to name the 2010 cubs, which made their public debut in April 2010. The winning names were Shani, Nala, and Adamma. The 2013 cubs were named Thulani, Ime, Bahata, and Amara and the three males can still be found on-exhibit at the zoo. The Carter Giraffe Building, a section of African Plains, features indoor/outdoor viewing of the zoo's giraffes and southern ostriches (Struthio camelus australis), and is also home to spotted hyenas, common dwarf mongoose, and southern white-faced owls. In June 2009, two aardvarks imported from Tanzania joined the exhibit. In September 2010, the pair gave birth to a male named Hoover, the first to ever be born at the zoo. In 1924, the zoo became the first in North America to exhibit the species. 
Until 2009, the southwestern corner of African Plains was home to the endangered Arabian oryx and blesbok. Due to budget cuts and the unpopularity of the species with visitors, they were phased-out of the collection. This section of the exhibit remains empty.  In 2017 they received two baby cheetahs from the San Diego Zoo. Cheetahs are now part of their animal encounter programs. They were replaced by the hyenas.
