Massive thank you to my course team and our wonderful learners for an amazing six weeks in the world of dinosaurs: http://edx.org/course/dinosaur-ecosystems

See you next time!


Highlights from December 2018 to January 2019 trip to New York and Argentina

Visit the American Museum of Natural History and then flew down to
Argentina for field work, research + Dinosaur Ecosystems MOOC filming w/ Diego Pol of the Museo Paleontológico Egidio Feruglio. Saw a number of importance specimens across Neuquen and Rio Negro provinces and meet a number of wonderful colleagues for the first time: Rodolofo Corio, Leonardo Filippi and Jorge Calvo. Visited Federico Agnolin and colleagues at the Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” in Buenos Aires. Worked with Santiago Reuil to produce two cardboard dinosaur masks for Dinosaur Ecosystems.


Amber symposium in Bangkok, Thailand

Had a great trip to Bangkok for a Burmese amber workshop.


Research visit to the Verulamium Museum in St. Albans, UK

Had a wonderful time working with the curator David Thorold and Tom Kaye to LSF Roman artefacts.


HKU research visit by Thomas G Kaye

Great having Tom Kaye at HKU Department of Earth Sciences to work on a range of ongoing projects supported by the HKU Faculty of Science RAE Improvement Fund.


Australia October 2019: SVP Annual Meeting & ANSTO neutron and synchrotron imaging experiments

This was one of my favourite SVPs so far. It was a pleasure to moderate the bird origin and evolution session with Aurore Canoville and to contribute a talk on flight-related soft tissues. PhD student Arindam Roy talked about palaeocolour reconstruction at the podium symposium ‘From molecules to macroevolution’. Had an awesome experience conducting neutron and synchrotron imaging experiments with Joseph Bevitt of ANSTO.


Amniote palaeocolour reconstruction

What colour were fossil animals?

Find out about colour reconstruction in ancient reptiles and mammals as well as a new study framework in our open access Biological Reviews paper: https://onlinelibrary.wiley.com/doi/10.1111/brv.12552

Congratulations to Arindam Roy on his first peer-reviewed publication!


Summer fieldwork in Wyoming, USA

Summer fieldwork in central eastern Wyoming with Tom Kaye included a visit to the home of T. rex and Triceratops! 🦖🤠


Born to run: early birds ready to fly after hatching

Using LSF imaging, we revealed feathering around the body of a ~126 million year old enantiornithine bird hatchling🐣 This indicates that it came ‘out of the egg running’ and was probably ready-to-fly! 🐥 This precocial strategy appears to be the primary one among early birds, unlike most living birds which have helpless newborns that require more parental care. Troodontids may also have been precocial so precociality probably had deeper theropod origins.


The identify of the first discovered fossil feather

The first discovered fossil feather was originally referred to the iconic bird Archaeopteryx. Using LSF, we reveal that the long lost quill of the fossil specimen and use its complete morphology to show that it does not match the plumage of known Archaeopteryx specimens. Instead, the feather seems to belong to another feathered dinosaur!


Highlights from December 2018 – January 2019 research trip to Argentina

  • Talk on theropod flight origins at Investigadores y Becarios UEL, Fundacion Miguel Lillo in Tucuman as a guest of Prof. Pablo Goloboff:

  • Carnotaurus and paravian specimens at Museo Argentino de Ciencias Naturales “Bernardino Rivadavia” in Buenos Aires w/ Fernandos Novas, Federico Agnolin and colleagues:
  • Dinosaur footprints in the Maastrichtian Yacoraite Formation of Jujuy Province.
  • Visits to the spectacular Parque Nacional Talampaya & Parque Provincial Ischigualasto in Patagonia:
  • Visit to Ricardo Martinez’s lab and the early dinosaurs in the Museo de Ciencias Naturales in San Juan.
  • Visit to Museo Paleontológico Egidio Feruglio in Trelew w/ Diego Pol at 
  • Fieldwork in the Carnotaurus locality. Late Cretaceous & Palaeogene La Colonia Formation of Chubut Province:

Pterosaur feathering discovering in Nature Ecology and Evolution

Delighted to share a co-authored Nature Ecology & Evolution paper w/ Prof. Michael Benton (Bristol) and Prof. Baoyu Jiang (Nanjing) about pterosaur integumentary structures.

It was a great pleasure to #LSF the Nanjing specimen with Tom Kaye to show the extent of its soft tissue preservation (black in the image).

The integumentary structures we describe look just like those of feathered theropod dinosaurs, which we suggest indicates a deeper origin of feathers.

International Palaeontological Congress 5 – Paris, France

 From July 9th – 13th, I attended the fifth International Palaeontological Congress in Paris, France. I presented two talks on theropod flight origins and my collaborator Dr. Diego Pol presented a third talk on our recent work on phylogenetic methods. The congress was really enjoyable and productive. I joined a post-congress fieldtrip to the famous Early Cretaceous Angeac-Charente locality, which involved helping with their on-going excavations. I produced this video on it as part of the upcoming second edition of my HKU MOOC Dinosaur Ecosystems.

Symposium poster                                   Group photo of attendees

From March 29th-31st, our lab hosted the inaugural International Pennaraptoran Dinosaur Symposium at HKU with Prof. Xing Xu (IVPP). 30 attendees from 7 countries shared and discussed their work on pennaraptoran dinosaurs to deepen our understanding of avian and flight origins. The symposium: documented existing points of consensus and disagreement in the field; built consensus in new areas through symposium discussions; reported cutting-edge discoveries in new areas of research and discussed their future directions. The results of the symposium will be published in a journal volume in 2019 and focuses on the consensus that was built on unresolved issues.

Mr. Arindam Roy collecting his best talk prize on day 2. Mr. Josef Stiegler (GWU, USA) was awarded the best talk prize on day 1.  Thanks to our judges Dr. Peter Makovicky and Dr. Hans Larsson!


A new species of crownward troodontid

Almas ukhaa, a short-snouted crownward troodontid

In December 2017, Dr. Rui Pei, an ex-VPL postdoc, announced the discovery of Almas ukhaa, a new species of short-snouted crownward troodontid from the Late Cretaceous of Mongolia. Almas is described in the paper ‘Osteology of a new Late Cretaceous troodontid specimen from Ukhaa Tolgod, Ömnögovi Aimag, Mongolia‘ in American Museum Novitates.


The mandible of Gigantoraptor, the largest beaked theropod

The mandible of Gigantoraptor, the giant oviraptorosaur.

In November 2017, Ms. Fion Wai Sum MA, an ex-undergraduate student of mine, published her first scientific paper in Scientific Reports on the ‘Functional anatomy of a giant toothless mandible from a bird-like dinosaur: Gigantoraptor and the evolution of the oviraptorosaurian jaw‘.

This paper is the first detailed description of the spectacular jaw of this iconic oviraptorosaur and leverages new insights to comment on the evolution of the oviraptorosaurian jaw. This study was part of Fion’s faculty Overseas Research Fellowship and departmental Final Year Project, both of which were co-supervised by Prof. Xing Xu of the IVPP. This project was completed in collaboration with colleagues in Inner Mongolia, including Prof. Lin Tan of the Longhao Institute of Geology and Paleontology.

Fion is continuing her work on the oviraptorosaur skull as an MSc student of Dr. Stephen Brusatte at the University of Edinburgh. Fion will be starting a PhD on the same subject at the University of Birmingham in October 2018. Her supervisors will be Dr. Stephan Lautenschlager, myself and Prof. Richard Butler.


A new species of asymmetrically feathered troodontid

Jianianhualong tengi an asymmetrically feathered troodontid

Jianianhualong tengi  is from the Early Cretaceous of Northeastern China. It has transitional features and along with Sinusonasus provides evidence of mosaic evolution in troodontids.

The asymmetrical feathers in this taxon represent the first record in a troodontid. Taken together with other paravian feathering data, this new find suggests that the common ancestor of Paraves possessed asymmetrical feathers too.

The study is co-lead with Prof. Xu Xing of the Institute of Vertebrate Paleontology and Paleoanthropology (Chinese Academy of Sciences) and Prof. Philip Currie of the University of Alberta (Canada).

Feathered dinosaur Anchiornis in the flesh

The wing of the stemward paravian, Anchiornis.

In this study, we produced the first quantitative body outline of a feathered dinosaur with the help of laser-based fossil imaging (laser-stimulated fluorescence imaging). We used these data as other soft tissue details of the wing and feet to comment on the functional anatomy of stemward paravians.
