Australian dinosaurs and the Emu Man

Australia dinosuar tracksThere are over 1000 dinosaur tracks, with the largest variety discovered so far of more than 20 different dinosaurs types, preserved in a huge area, now becoming known as the Western Australia Dinosaur Coast or Australia's Jurassic Park.

These coastal dino footprints have been documented near the beautiful beach of Broome, along the Dampier Peninsula over a 16 mile stretch. There is a suggestion that the number of sites could be over 15 and range over a distance of 125 miles.

No Australian dinosaur fauna fossils have previously been found for this period (dated at 130 million years old), yet these dinosaurian tracksites fossilised in the Broome sandstone have a big variety over a big distance. How, why, when?

dinosaurian tracksitesTracks range in size from small (20 cm) to very large (>1.5m). Over 20 different types of tracks exist, including those of theropods (3-toed bipedal carnivores), sauropods (massive, long-necked quadrupedal herbivores) ornithopods (bipedal herbivores) and thyreophorans (armoured quadrupedal herbivores covered in plates and spikes).

Lithofacies analysis revealed 16 repeated facies types that occurred in three distinctive lithofacies associations, indicative of an environmental transgression between the distal fluvial to deltaic portions of a large braid plain, with migrating sand bodies and periodic sheet floods. The main dinosaurian track-bearing horizons seem to have been generated between periodic sheet floods that blanketed the preexisting sand bodies within the braid plain portion of a tidally influenced delta, with much of the original, gently undulating topography now preserved over large expanses of the present day intertidal reef system.

How were so many different tracks, over such a wide area, with a wide variety of local conditions, preserved long enough to have been fossilised?

Ultra rapid or instant transformation and fossilisation of the host material?

The same event that also wiped out or evolved these Australian animals?

Marala, the Emu Man, and Australian Aboriginal dinosaur mythology

Were Australian Aborigines around to witness the formation of diamonds at the Argyle mine, as passed on in their oral history?

Is the Aboriginal folklore of the Marala the Emu Man an explanation of what they could see but did not observe this time, or did they?

Marala Emu ManOf course, the dinosaur tracks have always been known to the Aboriginal custodians of the land. For thousands of years, dinosaur tracks in the 130-million-year-old sandstone have been part of the cultural heritage of the people of the Dampier Peninsula and greater west Kimberley. The tracks are integral to a ‘song cycle’ that extends along the coast from Bunginygun (Swan Point, Cape Leveque) to Wabana (Cape Bossut, near La Grange) then inland to the southeast over a total distance of approximately 450 kilometres, tracing the journey of a Dreamtime creator being known as Marala or ‘Emu Man’.

Australian Aboriginal mythologyOne of the important Bugarrigarra beings within the Song Cycle is called Marala [marala] The folklore of footprints in stone: from Classical to Antiquity to the Present. Marala, also referred to as ‘Emu Man,’ was the ‘lawgiver,’ and instilled in country the codes of conduct for behavior needed to help ensure its well-being, and there are numerous Bugarrigarra stories and parts of stories in which he features. In the process of moving through the Song Cycle from south to north, as well as in and out of the sea, Marala left behind three-toed tracks. He also left behind the grooved impressions of his tail feathers (his ‘ramu’ or ceremonial engravings) when he sat down to rest and create his law ground. Today, three-toed dinosaur tracks (typically those assigned to Megalosauropus broomensis) and impressions of cycad-like bennettitaleans (Marala's tail feather impressions and ramu) are seen as testimony to Marala's journey as narrated in the Song Cycle. A concentration of M. broomensis tracks at a Song Cycle place on Cable Beach is also known as Maralagun [place of Marala].
