Well it’s been a wild month-and-a-third of competition, but Dinosaur March Madness 2023: Rising Stars has come to an end! Congratulations to our four finalists: Big Parrot, Meme Reboot, Spikey Creatur, and Gay. After a final brutal slugfest Caihong emerged as the victor by a significant margin, winning all three separate matches. Shockingly, the Queer Neurodivergent Web Site felt rather fond of the shiny fluffy rainbow colours dinosaur!
Caihong joins the hallowed halls of DMM winners past, alongside Corvus, Maiasaura, Halszkaraptor, and Amargasaurus, making it the third maniraptoran to claim the top spot! The people love a bird, is what we’re learning.
A huge thank you to the members of the ADAD team who pulled this all together with planning, researching, writing, arting, the whole lot! @zygodactylus, @raptorcivilization, @i-draws-dinosaurs, @otussketching, @albertonykus, everyone who’s put their time and effort into this project is an absolute legend.
And thank you so much to everyone who voted, made posts and debated in the notes!! It was absolutely wonderful to see how much people got into it especially after having taken A Bit of a hiatus, the enthusiasm that all of you have really makes the contest what it is!
That’s all for now, we hope y’all had a fun time and got to learn about some sick new dinosaurs! And coming up next year, of course, we’re leaving the dinosaurs behind... on our long-awaited trip... into the Permian

It Came From The Trash Heap (We Don't Talk About Kholumolumo)
A wastebasket taxon is what happens when species can't be easily classified and instead get hurled into a "catch-all" category.
…But that's not the only kind of taxonomic tangle that can befall a new discovery.
When a scientific name is assigned to a new species, but it isn't given a corresponding formal description and type specimen, it becomes a nomen nudum – a "naked name". Without a proper description and assigned holotype the name isn't valid, and the new species isn't technically accepted by the wider scientific community.
This has even happened to some surprisingly famous names. In the 1920s Velociraptor mongoliensis was briefly given the nomen nudum "Ovoraptor djadochtari" before getting its much more familiar name when it was officially described. Meanwhile the giant pterosaur Quetzalcoatlus northropi was stuck as a nomen nudum for decades, only finally getting a proper published description in 2021.
And there's another particular long-standing nomen nudum that became mildly infamous – "Thotobolosaurus", the "trash heap lizard".
Tumblr media
Discovered next to a literal trash pile in the village of Maphutseng in Lesotho, a few scattered and broken bones of this "prosauropod" sauropodomorph dinosaur were first found in 1930. But it wasn't until the mid-1950s that a more extensive bonebed began to be unearthed at the site, and over the next decade over 1000 fossil fragments were collected.
In the mid-1960s the remains were initially classified as belonging to Euskelosaurus browni (which is now considered to be a wastebasket taxon), but just a few years later in 1970 the "Maphutseng Beast" was re-evaluated as a species new to science. It was referred to as "Thotobolosaurus mabeatae" – based on the local name of the discovery site, "Thotobolo ea ‘Ma-Beata" (trash heap of Beata’s mother) – but this name was never actually formally published.
Despite "Thotobolosaurus" being an undescribed nomen nudum it nonetheless went on to be repeatedly referenced in scientific literature over the next few decades, and appeared in several popular dinosaur books (even as recently as 2020!).
In the mid-1990s it was alternatively named "Kholumolumosaurus ellenbergerorum" in a Ph.D. dissertation, with this name derived from the kholumolumo, a reptilian creature in Sotho mythology, and the Ellenberger brothers who worked on the site. But this also didn't count as a formal publication and instead became a second nomen nudum for the species.
Eventually, 90 years after the first bones were found and 50 years after the debut of the name "Thotobolosaurus", this long-neglected sauropodomorph was finally given a proper published full anatomical description in 2020.
And it also got a third name, this time officially valid, based on the second one from the 1990s: Kholumolumo ellenbergerorum.
For something associated with trash for so long, Kholumolumo is actually now one of the most completely-known prosauropods. At least five different individuals were present in the collected fossil material, possibly as many as ten, and between them most of the full skeleton is represented – with the exception of the skulls, which are only known from a couple of small fragments.
We now know Kholumolumo was rather heavily-built, with chunky limb bones and unusually short shinbones. It would have been one of the biggest animals around in the Late Triassic (~210 million years ago), measuring at least 9m long (~30') and weighing around 1.7 tonnes (1.9 US tons), but despite its size it seems to have still been bipedal.
Due to the highly disarticulated nature of the bones the fossil site may have been a "bone accumulation area", a place where dismembered bits and pieces of different carcasses were regularly carried to be eaten by a predator or scavenger – essentially a trash heap, fittingly enough. A couple of "rauisuchian" teeth have actually been found among the remains, which might indicate what was chomping on these particular Kholumolumo.

opposite to conventional representation, massopoda sculpture of the late Triassic period was often brightly painted. Imagine the ancient city roads flanked with kneeling Kholumolumo Ellenbergerorum warriors such as this one

VOTE JAKAPIL FOR DINOSAUR MARCH MADNESS
@a-dinosaur-a-day
No other contestant in the final four is such A Creature™️ the way that Jakapil is. Jakapil is simultaneously the ultimate being to exist from the perspective of a dinosaur-obsessed child and a fascinating, paradigm-shifting paleontological enigma. Literally the perfect dinosaur, what more could you want
Why vote for Jakapil?
the most likely scenario here is that this guy represents a hundred million year old ghost lineage of basal thyreophorans that we’ve never discovered before. The less likely scenarios are bipedal armored ceratopsian or a completely new kind of ornithsician, both of which have been genuinely considered by some paleontologists! Whatever the case, Jakapil represents a brand new, never-before seen lineage of dinosaurs unlike anything we’ve ever known before, and that’s SO COOL
Aesthetically, this is a bipedal armored dinosaur with tiny abelisaur-grade arms, estimated to be less than 5 ft long and 15 lb (or 1.5 m and 7 kg max). Literally perfect. I’m really bad at visualizing measurements but I’m pretty sure you could pick it up and hold it in your arms if you tried. Sure you could do that with Heracles or Caihong, but you don’t need a Time Machine to pick up parrots and shiny bird things - there’s nothing like Jakapil for you to hold and snuggle today
They’re so friggin weird. It’s got jaws like a ceratopsian or a heterodontosaur, a jaw bone that no other basal thyreophorans have, arm anatomy shockingly similar to abelisaurs, and THEY CAN CHEW. I know that chewing seems really normal to us humans but it’s so weird to see outside of mammals. Practically the only other dinosaurs that chew are ornithopods. Jakapil seems like it’s trying to be as many kinds of dinosaur as possible, which further supports my statement that it is the Ultimate Dinosaur
It’s armored and covered in spikes. ‘Nuff said
Also a friendly reminder that the only other known bipedal thyreophoran is Scutellosaurus, which was from Early Jurassic Europe. Jakapil is from late Cretaceous South America, so this guy just popped up across the world a hundred million years later with practically no trace of its ancestors. How did this happen? What the fuck were its ancestors doing in that time? Heracles may have given us neat answers to New Zealand-y questions, but Jakapil gave us questions we didn’t even know needed to be asked
I’ve said it once and I’ve said it again, South America’s fauna has been friggin' amazing since the Cretaceous and never stopped. Automatic points for being a South American dinosaur. This guy lived alongside Giganotosaurus and Buitreraptor!!
What about the other contestants, you may ask? Kholumolumo is only here for the meme. Outside of the funny name and it’s absurdly convoluted history to getting formally named, what do you actually know about it? How much does it contribute to our understanding of dinosaurs compared to the other contestants?
Caihong is basic. I’m sorry but I won’t back down from this (for another few months at least). I love dromaeosaurs as much as the next person, but literally all that Caihong has going for it is it’s ultra-inridescence. Any other Chinese dromaeosaur could provide the rest. Look past your instinctual love of shiny things and vote for something that breaks away from everything we thought we knew to become something truly unique!
As for Heracles... I actually have nothing bad to say about Heracles, I love New Zealand's fauna and giant flightless birds (especially on islands). But while I love Heracles for everything it stands for, I feel like Jakapil stands for so much more. Heracles is a wonderful addition to our knowledge of it's lineage and environment, but also... is it really that surprising to find a giant flightless bird in New Zealand that belongs to that a family endemic to New Zealand? Jakapil is just such a bizarre, fascinating, unexpected discovery from so many perspectives. It is truly the ultimate dinosaur, and we should honor it as such
As of the time of writing there's still four days left at the polls and Jakapil is a steady second place in all three of them. We still have time to win this for Jakapil and dethrone Caihong!

Round Four: Kholumolumo vs Bajadasaurus
Kholumolumo ellenbergerorum
Tumblr media
Artwork by @alphynix, written by @i-draws-dinosaurs
Name meaning: Kholumolumo (giant reptilian dragon from Sotho folklore) named for Paul and François Ellenberger (the original excavators of the fossils)
Time: 210 million years ago (Norian stage of the Late Triassic)
Location: Lower Elliot Formation, Lesotho
Kholumolumo is an old friend with a new name. Its previous informal name, “Thotobolosaurus” meaning “trash heap reptile”, was truly magnificent and became one of the great memes of Ye Olde 2010s Palaeo Tumblr! Needless to say it was a bittersweet moment to see our old buddy finally published but lose its iconic name in the process. Rest in peace, Trash Heap Lizard.
The reason it wound up with that name is because the fossils were in fact found basically right next to the local rubbish dump of the village of Maphutseng in 1955. The trash pile turned out to be sitting on a bone bed of around five to ten animals, and over the course of several years they were excavated and moved to the University of Cape Town. Unfortunately, and perhaps appropriately to the name, the subsequent study of these fossils ended up being a complete trash fire. Specimens went missing that have never been found, professional relationships fell apart, and the animal itself wasn’t mentioned in the literature until 1970 when it was dropped into a discussion on the stratigraphy of the Elliot formation and named “Thotobolosaurus mabeatae” without any description of the fossils. This made the name “Thotobolosaurus” a nomen nudum (naked name) and thus invalid.
Finally in 2020 all the tribulation paid off and it received a proper initial description, although many fossils that weren’t lost in the chaos still remain under study and could be the subject of future papers. It’s nice to see our beloved trash heap of a dinosaur finally coming into its own!
Bajadasaurus pronuspinax
Tumblr media
Artwork by @i-draws-dinosaurs, written by @i-draws-dinosaurs
Name meaning: Downhill reptile with forward-bent spines
Time: 145 to 132.9 million years ago (Berriasian to Valanginian stages of the Early Cretaceous)
Location: Bajada Colorado Formation, Argentina
Initially published in 2019, Bajadasaurus became pretty much instantly popular because of its bizarre, forward-pointing double mohawk of spines on its neck. The only other dinosaur like it is Amargasaurus, a dicraeosaurid sauropod that was thought to be entirely unique in its neck spines. The initial hypothesis in the paper describing Bajadasaurus was that the front-facing spines would have been passive defense structures that could impale predators that tried to make a charge at the otherwise-vulnerable head. However, a recent paper on Amargasaurus in 2022 has potentially turned that idea on its spiny head, suggesting that based on the interior bone histology of the spines as well as the outer texture Amargasaurus’ multi-pronged neck actually supported some sort of fleshy sail instead! The study didn’t include Bajadasaurus in its analysis, but based on its similarities to Amargasaurus it’s reasonable to assume that this forward-swept spine was also more of a sail, turning a deadly defensive fortification into a showy display feature!

Round One: Ngwevu vs Kholumalumo
Tumblr media Tumblr media
Factfiles:
Ngwevu ntoloko
Tumblr media
Artwork by @i-draws-dinosaurs, written by @i-draws-dinosaurs and @zygodactylus
Name meaning: Grey skull
Time: ~190 to 180 million years ago (Pliensbachian to Toarcian stages of the Early Jurassic)
Location: Clarens Formation, South Africa
Ngwevu is a dinosaur with a case of baby-face so bad it was classified as another genus for 40 years. Initially discovered in 1978 and thought to be a specimen of Massospondylus, turns out it was just a really baby-looking prosauropod of a different kind! Many times in evolution animals will retain “baby” characteristics into adulthood - the classic and easily recognizable trait being large, round eyes, but also other features such as stunted proportions and chunkier limbs, depending. It seems that Ngwevu went through one of these processes, looking more similar to juveniles of other prosauropods (such as Massospondylus) than adults, all while actually being adults themselves. Predictably, it had a squat face with large eyes, a wide snout, robust proportions, and a thick body - babified Massospondylus! It probably had a more generalist diet than its cousin, indicating probable niche partitioning as the two lived in the same environment. The Clarens Formation, coming right after the Elliot, was an arid desert dominated by dunes, with a few types of dinosaurs including ornithischians, theropods, and other sauropodomorphs. In addition, fish, crustaceans, and invertebrates are also known from this location. 
Kholumolumo ellenbergerorum
Tumblr media
Artwork by @alphynix, written by @i-draws-dinosaurs
Name meaning: Kholumolumo (giant reptilian dragon from Sotho folklore) named for Paul and François Ellenberger (the original excavators of the fossils)

Amanzia greppini
Tumblr media
Artwork by @i-draws-dinosaurs, written by @i-draws-dinosaurs
Name meaning: Named for 19th-century geologists Amanz Gressly and Jean-Baptiste Greppin
Time: 157 million years ago (Kimmeridgian stage of the Late Jurassic)
Location: Reuchenette Formation, Switzerland
Amanzia has been through a real odyssey of classifications. First discovered c. 1860, it was mistaken for a theropod and named Megalosaurus meriani in the 1870s, reclassified as a sauropod and named Ornithopsis greppini in 1922, then re-reclassified as a species of Cetiosauriscus in 1927, and then basically ignored ever since. Poor guy’s got an identity crisis now.
The actual fossils weren’t properly cleaned until 2003, and subsequent study in 2020 named it and revealed it was probably a turiasaur, an early-branching group of large sauropods that was unknown before the 2000s, so nobody working on it in the century and a half beforehand could have had any idea what they’d really found!

Round Three: Mbiresaurus vs Kholumalumo
Mbiresaurus raathi
Tumblr media
Artwork by @i-draws-dinosaurs, written by @i-draws-dinosaurs
Name meaning: Raath’s reptile from Mbire (after the Mbire district of Zimbabwe, and in honour of palaeontologist and discoverer Michael Raath)
Time: ~ 230 million years ago (Carnian stage of the Late Triassic)
Location: Pebbly Arkose Formation, Zimbabwe
There was once a time… before titanosaurs… before diplodocids… before any sauropod… when sauropodomorphs were simply Just Some Little Guy. And that is where Mbiresaurus, oldest African dinosaur ever found, comes in!
Mbiresaurus was named in 2022 from Zimbabwe, and is the only dinosaur yet named from the Pebbly Arkose formation. It’s known from a beautifully complete skeleton that has all the features of a classic Early Dinosaur. It is small, has long gangly legs and arms, and a lil head with vaguely pointy kinda multipurpose teeth. The fact that all the wild diversity and enormous size of the sauropods came out of something like this is hard to imagine, but evolutionarily step by step these little scampery dudes would work their way up!
