Hobbit Wrists and Jurassic Feathers

Hobbit Wrists

A comparison of wrist bones like those found in the “hobbit” human (left) and those of a modern human suggest that the diminutive hominin is a unique species, scientists say.

It is one of those busy news days, especially in terms of fossil updates.


The two big fossil discovery news items are primate and aves related, and of interest to Cryptomundo. One is the new Science report that a study of the wrist bones of Homo floresiensis confirms it is a new species, and not an abnormal human.

The other finding is that there were feathers on velociraptors.

Breaking fossil news on two fronts gives insights to the fact that all we know is merely part of yesterday’s unknowns.


The tiny, human-like creature living and using tools in Indonesia just 18,000 years ago really was a distinct species, not just a malformed modern human.

That is the clear implication of a new study of the so-called “hobbit”. It states that the creature had wrist bones almost identical to those found in early hominids and modern chimpanzees, and so must have diverged from the human lineage well before the origin of modern humans and Neanderthals.

Palaeontologists have battled bitterly over the diminutive skeleton ever since its discoverers described it as a new species, Homo floresiensis, three years ago.

Its exceptionally tiny brain simply did not fit with the current understanding of human evolution, particularly since no other hominid fossils in the last 3 million years, and none outside of Africa, had such a small brain.

This dissonance led sceptics to argue that the hobbit must be merely a modern human with some form of microcephaly – a disorder which causes an abnormally small head and brain.

Most of the argument has centered on the skull, even though much of the rest of the skeleton was excavated at the same time. When Matthew Tocheri, a palaeoanthropologist at the Smithsonian Institution in Washington, DC, happened by chance to see casts of the specimen’s wrist bones, he knew they told an important story.

Ancient structure

Tocheri, an expert in the evolution of the human wrist, could see immediately that the hobbit’s wrist bones looked just like those of a chimpanzee, or an early hominid such as Australopithecus, and had none of the specialisations for grasping that are seen in the wrist bones of modern humans. A careful statistical comparison gave the same conclusion.

“The modern human wrist hasn’t looked like this for at least 800,000 years, and maybe much longer,” says Tocheri. “It was immediately apparent to me that the hobbit is the real deal.”

Developmental abnormalities such as microcephaly are unlikely to change the shape of the wrist bones, he adds, because the shape of these bones is laid down very early in development, long before the genes controlling growth rates become active.

Other soon-to-be-published studies of the hobbit’s foot bones, upper arm and shoulder also suggest that its anatomy differed from that of modern humans. “As you add these up, you do certainly get a picture of something distinct and not human,” says Chris Stringer, an authority on human evolution at the Natural History Museum in London, UK.

However, Robert Martin, a primatologist at the Field Museum in Chicago, US, who is the leading advocate of the microcephaly explanation, remains unconvinced. No one has studied the wrist bones of microcephalic humans, he notes, so it is pure conjecture to say they would not look like the hobbit’s bones.Bob Holmes, Journal reference: Science (DOI: 10.1126/science.1147143)

Feathered Jurrasic

A recent museum exhibition of feathered dinosaurs gives one view of how they may have appeared.

A new look at some old bones have shown that velociraptor, the dinosaur made famous in the movie Jurassic Park, had feathers. A paper describing the discovery, made by palaeontologists at the American Museum of Natural History and the Field Museum of Natural History, appears in the 21 September issue of the journal Science.

Scientists have known for years that many dinosaurs had feathers. Now the presence of feathers has been documented in velociraptor, one of the most iconic of dinosaurs and a close relative of birds.

The fossil specimen that the group examined was a velociraptor forearm unearthed in Mongolia in 1998. They found on it clear indications of quill knobs — places where the quills of secondary feathers, the flight or wing feathers of modern birds, were anchored to the bone with ligaments. Quill knobs are also found in many living bird species and are most evident in birds that are strong flyers. Those that primarily soar or that have lost the ability to fly entirely, however, were shown in the study to typically lack signs of quill knobs.

‘A lack of quill knobs does not necessarily mean that a dinosaur did not have feathers,’ said Alan Turner, lead author on the study and a graduate student of palaeontology at the American Museum of Natural History and at Columbia University in New York. ‘Finding quill knobs on velociraptor, though, means that it definitely had feathers. This is something we’d long suspected, but no one had been able to prove.’

Previous signs of feathers on dinosaurs had been restricted to fossils found in a particular kind of lake sediment that favoured preservation of small-bodied animals.

The velociraptor in the current study stood about three feet tall, was about five feet long, and weighed about 30 pounds. Combined with its relatively short forelimbs compared to a modern bird, this indicated it lacked volant, or flight, abilities. The authors suggest that perhaps an ancestor of velociraptor lost the ability to fly, but retained its feathers. In velociraptor, the feathers may have been useful for display, to shield nests, for temperature control, or to help it maneuver while running.

‘The more that we learn about these animals the more we find that there is basically no difference between birds and their closely related dinosaur ancestors like velociraptor,’ said Mark Norell, a Curator in the Division of Palaeontology at the American Museum of Natural History and co-author on the study. ‘Both have wishbones, brooded their nests, possess hollow bones, and were covered in feathers. If animals like velociraptor were alive today our first impression would be that they were just very unusual looking birds.’

The research team also included Peter Makovicky from the Field Museum in Chicago. The work was supported by the National Science Foundation and the American Museum of Natural History.

The American Museum of Natural History is one of the world’s preeminent scientific, educational, and cultural institutions. Since its founding in 1869, the Museum has advanced its global mission to explore and interpret human cultures and the natural world through a wide-reaching program of scientific research, education, and exhibitions. The Museum accomplishes this ambitious goal through its extensive facilities and resources. The institution houses 46 permanent exhibition halls, state-of-the-art research laboratories, one of the largest natural history libraries in the Western Hemisphere, and a permanent collection of more than 30 million specimens and cultural artifacts. With a scientific staff of more than 200, the Museum supports research divisions in Anthropology, Palaeontology, Invertebrate and Vertebrate Zoology, and the Physical Sciences. The Museum shares its treasures and discoveries with approximately four million on-site visitors from around the world each year. AMNH-produced exhibitions and Space Shows can currently be seen on five continents in engagements that reach audiences of millions. Source: American Museum of Natural History.

    Mr. Coleman, 2 questions if I may

    *Do you see any links between H. floresiensis and Orank Pendek?

    The most obvious deviation for me would be the feet, but aside of that?

    Which brings me to another question:

    *Do you think these cryptid hominids are capable of using tools?

    I mean we know now the chimpanzees are very proficient in using sticks to hunt ants and usin rocks to smash nuts. But what about our buddy Sasquatch?

    The questions are open to all of course. Please feel free to share your thoughts

  2. sschaper responds:

    Dinoaves, not dinosaurs. Yep. Note that they suggest that the ancestor of velociraptor flew. We might just have the ancestry backwards. And dinosaurs might not be all one family.

  3. mystery_man responds:

    That poster of “Meet the Folks” is amazing. Anyway to allow us to click on it for a larger size? I just think that is an awesome graphic.

  4. Ceroill responds:

    I’m with M_M, that’s a great pic!

    I’ve also read that some are dissenting about the new Floriensis finding, citing variability in wrist bones. I’ll give a quote from the latest at Strangeark “Dr. Eckhardt noted, in particular, that there is ‘a lot of variation in the form of wrist bones.’ Some variations, he said, are normal and others occur ‘as the result of various pathologies, such as from injuries or from anomalies of development.’ “ I still remember back in the 70’s when feathers on dinos was first made public. I drew a cartoon for some friends showing a T-Rex covered in puffy down like a baby chick. I dubbed it Tyrannosaurus Rex Fluffia. (Yes, I know it’s unlikely that’s how it really looked. It was meant to be humorous)

    You might have been right all this time, since a lot of paleonthologists are now speculating that the offspring of T-Rex might have sported a coat of proto-feathers during their early years of their life.

    So they might have looked like fluffy chicks… from Hell 🙂

  6. Ceroill responds:

    red, true, but in my cartoon it was a full grown T Rex with the head, legs, and tail poking out of a huge puffball of down, with the ‘hands’ barely visible.

  7. mauka responds:

    Wait so Homo Fl. was around 18,000 years ago. How long ago did modern humans come around?

  8. red_pill_junkie responds:

    mauka, current theories mantain H. sapiens appeared in Africa around 200,000 years ago, and then left the continent to spread to rest of the world around 100,000 years ago.

  9. Alligator responds:

    It’s almost a guarantee that science’s interpretation of the fossil record is constantly changing and will continue to change. When I was a kid, dinosaurs were drab-colored, cold-blooded, slow moving, stupid lizards in a swamp. Even the very term “dinosaur” came to mean something badly outdated or hopelessly outclassed in intelligence.

    No serious paleontologist or biologist holds those views anymore. In fact many dinosaur skulls show rather sizable brain cavities and room for medulla oblongata. When I expressed an opinion on a subject recently, someone called me a “real dinosaur.” My retort was that dinosaurs were one of the most diverse, successful and dominate lifeforms on the planet for over a 100 million years and it was only catastrophic external forces that wiped them out. And besides, we now know many were colorful, fast, alert and rather intelligent.

    Understanding and interpretation of existing life forms is constantly changing as well. For example: crocodiles show maternal instinct, they have a high degree of intelligence and can learn, they have a social hierarchy and their four chambered heart almost makes them endothermic. Twenty years ago, saying such stuff about crocs would have gotten you booted out of some institutions. But folks like the late Steve Irwin, Dr. Adam Britton and others have proven over and over, these animals are not what everyone wrote about in the textbooks written over the last few hundred years.

    Who knows? Maybe that bird at your feeder really isn’t a bird after all? Feathers and scales are basically made out of the same material.

    This discovery along with the discovery of the very large primate skull in Turkey(?) a few weeks ago are rewriting everything we know about the human/primate family. I think modern anthropology is really going to get a kick in the teeth sooner or later when an oversized primate skull is found in the Western Hemisphere. Much of the wilderness areas of both North America haven’t been really searched all that well. It’s now believed that they’ve found a new super volcano’s caldera it the vast South America’s wilderness area but because of its dense jungle growth haven’t yet determined its size. If they can’t find a super volcano that’s miles across, how do they expect us to believe that they’ve found all known species of primates when a very large portion of the world remains unsearched? Just this year they announced a new small primate species’ fossil that was found in Texas! The lack of courage found in the modern anthropological community astonishes me!

  11. sschaper responds:

    Show on National Geo right now about “primordial dwarfs” the main person they are examining is the exact same height as proportions – including skull – of the hobbits of Isla Flores, and he is an honor student. I also note that his ears are pointed, which is what legend would be the case with such people in Europe.

    He is perfectly proportioned, but 1/4 the mass of a normal adult.

    I don’t know what his wrist bones look like. But the argument that the hobbits could not make the tools is at least potentially refuted, as he too, has a small brain.

    In fact, they all have ears like this, and large noses, large eyes, etc. They all look related.

    Worth catching a repeat if one is interested in the hobbits.
