The last meal of a 75-million-year-old Tyrannosaur has been revealed by scientists – two baby Dinosaurs.

Researchers say the preservation of the animal – and of the small, unfortunate creatures it ate – shines new light on how these predators lived.

It is “solid evidence that tyrannosaurs drastically changed their diet as they grew up,” said Dr Darla Zelenitsky, from the University of Calgary.

The specimen is a juvenile Gorgosaurus – a close cousin of the giant T. rex.

This particular Gorgosaur was around seven years old – equivalent to a teenager in terms of its development. It weighed about 330kg when it died – about a tenth of the weight of a fully-grown adult.

The hind limbs of two, small bird-like dinosaurs called Citipes are visible beneath its rib cage.

“We now know that these teenage [Tyrannosaurs] hunted small, young dinosaurs,” said Dr Zelenitsky, one of the lead scientists in this study, which published in the journal Science Advances.

An array of earlier fossil evidence, including evident bite marks on the bones of larger dinosaurs that match tyrannosaur teeth, have allowed scientists to build a picture of how the three-tonne adult Gorgosaurs attacked and ate very large plant-eating dinosaurs which lived in herds.

Dr Francois Therrien, from the Royal Tyrell Museum of Palaeontology, described these adult tyrannosaurs as “quite indiscriminate eaters”. They probably pounced on large prey, “biting through bone and scraping off flesh,” he told BBC News.

But, Dr Zelenitsky, added, “these smaller, immature tyrannosaurs were probably not ready to jump into a group of horned dinosaurs, where the adults weighed thousands of kilograms”.

‘Toes poking through the ribcage’

The fossil was originally discovered in the Alberta Badlands in 2009 – a hotspot for dinosaur hunters.

Entombed in rock, it took years to prepare and it wasn’t immediately obvious that there was prey inside. Staff at Alberta’s Royal Tyrell Museum of Palaeontology eventually noticed small toe-bones sticking out from the ribcage.

“The rock within the ribcage was removed to expose what was hidden inside,” explained Dr Therrien, who is the other lead scientist in this study. “And lo and behold – the complete hind legs of two baby dinosaurs, both under a year old.”

Dr Zelenitsky said that finding only the legs suggested that this teenage Gorgosaurus “seems to have wanted the drumsticks – probably because that’s the meatiest part”.

The Gorgosaurus is a slightly smaller, more ancient species than T. Rex. Fully grown, these were – as Dr Therrien put it – “big, burly tyrannosaurs”.

They transformed as they matured. “Juveniles were much more lightly built – with longer legs and very blade-like teeth,” he explained. “Adults’ teeth are all much rounder – we call them ‘killer bananas’. “This specimen is unique – it’s physical proof of the juveniles’ very different feeding strategy.

While the adults bit and scraped with their powerful “killer banana” teeth, “this animal was selecting and even dissecting its prey – biting off the legs and swallowing them whole”.

Prof Steve Brusatte, a palaeontologist from the University of Edinburgh and the National Museum of Scotland, said that seeing prey in the dinosaur’s guts gave a real insight into the animals: “They weren’t just monsters, they were real, living things and pretty sophisticated feeders.”

Recalling a depiction of T. rex in the 1993 film Jurassic Park – where the giant dinosaur chased a car through the fictional theme park – Prof Brusatte added: “A big, adult T. rex wouldn’t have chased after a car – if cars or jeeps were around back then – its body was too big, and it couldn’t move that fast.

“It would be the youngsters – like this gorgosaur – the children of T. rex that you’d have to keep an eye on.”

The Commander of the Sri Lanka Navy, Vice Admiral Damian Fernando attended the 15th edition of Trans-Regional Seapower Symposium, organised by the Italian Navy in Venice in Italy, on 6 and 7 October 2026.

The symposium was held at the Italian Navy‟s historic Arsenal in Venice under the theme “From Regional Waters to Global Influence: Generating Effects Across the Midland Seas of the World”.

Organised biennially by the Italian Navy since 1996, the symposium brings together heads of foreign navies, naval representatives, academics, industry representatives and scientific researchers to discuss maritime security and the role of regional maritime dynamics in shaping the global balance.

The sessions of the symposium aimed to present an analysis of the relevance and influence of regional dynamics on global balances and their relative implications within the maritime domain.

Thus, topics discussed included; ‘Geopolitical Background: Global and Regional Dynamics in Comparison,’ ‘Pivotal Role of Cooperation among Regional Alliances as Security Providers,’
‘Maritime Regional Security Complexes, Global Order and Sea-Based Flows – What Role for Navies?,’ ‘New Arctic Chessboard: Seapower, Resources and the Race for Connectivity,’ ‘Future-
Proof Capabilities: A Naval Force Designed to Operate Across Oceans, Act Within Regions and Deliver Effects on the Ground,’ ‘Future Seas: Industrial Scale, Decisive Mass and Innovation –
Securing the Maritime Domain’ and ‘Future-Proof Leadership: Preparing Maritime Commanders and Sailors for Complexity,’

Cooperation fostered through symposiums of this nature, which bring together a multitude of global maritime stakeholders, will enable the Sri Lanka Navy to respond collectively to maritime
challenges, in pursuit of maintaining a safe, secure, prosperous and a stable ocean region.

Elephant enrichment programme centred on the Thabbowa Reservoir proves successful

Published

As part of the new government’s initiative to formulate scientifically grounded, long-term solutions to the human-elephant conflict, a programme aimed at sustainably fulfilling the natural food and water requirements of wild elephants within forest ecosystems is being successfully implemented.

Spearheaded by the Ministers of Environment, guided by the Secretary to the Ministry of Environment, and supported by all affiliated institutions, this initiative transforms tanks (reservoirs) and forest tracts in high-conflict areas into enriched zones for wild elephants.

To facilitate this forest enrichment drive, 113 forests have already been declared protected reserves under the Vanaspathi National Programme. The initial phase of establishing tank enrichment zones was launched around the Kala Wewa and Thabbowa reservoirs.

Accordingly, the Ministry of Environment and ‘Clean Sri Lanka’ jointly carried out an initiative to develop these reservoir
catchments into designated enrichment zones.

A year ago, an operation to eradicate invasive plant species that posed a severe environmental threat to the Thabbowa reservoir precinct was conducted with the comprehensive labour and
technical support of government officials, environmental scientists, the tri-forces, and residents.

Since the new government’s policy of “A Sustainable Biosphere, An Evergreen Life” is practically implemented at the ground level, officials from the Department of Wildlife Conservation and the Department of Forest Conservation have been continuously monitoring the ongoing progress and
field conditions of this collaborative project under ministerial directives.

During these field reviews, it was observed that following the removal of invasive flora, the tendency of wild elephants to wander into villages searching for sustenance has notably declined; instead, they increasingly frequent the naturally regenerated grasslands along the reservoir fringes.

Having proven this ecological model’s success through trials at Thabbowa and Kala Wewa, the Ministry of Environment has finalized all necessary blueprints to swiftly replicate it across other sensitive wetland systems and reserve zones where human-elephant conflict is prevalent.

By enriching wildlife habitats, this sustainable, eco-friendly, and scientific strategy protects human lives and cultivated farmlands while securing space for wild elephants in their native habitats, continuing to show promising results across high-conflict regions.
