Triceratops Had Huge Nose to Control its Body Temperature, Suggests Curious Scientist

Scientists wanted to know why the iconic triceratops had such an unusually large nose compared to most species—both past and present.

Their new study shows the triple-horned dinosaur had a huge nose to help control its body temperature.

The team used CT scans of fossilized Triceratops skulls and compared their structures with modern animals including birds and crocodiles.

Through direct observation and inference, the research team reconstructed how nerves, blood vessels and structures for airflow fit together in the skulls.

They concluded that horned dinosaurs probably used their noses not just for smelling but also to help control temperature and moisture. Project Research Associate Dr. Seishiro Tada, from the University of Tokyo Museum in Japan, wondered about moisture control while studying a fossilized triceratops.

“I have been working on the evolution of reptilian heads and noses since my master’s degree,” said Dr. Tada.

“Triceratops in particular had a very large and unusual nose, and I couldn’t figure out how the organs fit within it even though I remember the basic patterns of reptiles.

“That made me interested in their nasal anatomy and its function and evolution.”

Horned dinosaurs (or Ceratopsia) had some of the most elaborate skull types—and Triceratops was the most iconic and instantly recognizable.

But due to its relative uniqueness, the internal anatomy of Triceratops skulls has been poorly understood, until Dr. Tada explored the internal soft tissues using modern tools at their disposal.

“Employing X-ray-based CT-scan data of a Triceratops, as well as knowledge on contemporary reptilian snout morphology, we found some unique characteristics in the nose and provide the first comprehensive hypothesis on the soft-tissue anatomy in horned dinosaurs.

“Triceratops had unusual ‘wiring’ in their noses.

“In most reptiles, nerves and blood vessels reach the nostrils from the jaw and the nose. But in Triceratops, the skull shape blocks the jaw route, so nerves and vessels take the nasal branch.

“Essentially, Triceratops tissues evolved this way to support its big nose.

“I came to realize this while piecing together some 3D-printed Triceratops skull pieces like a puzzle.”

The findings, published in the journal The Anatomical Record, also revealed a special structure in Triceratops’ nose called a respiratory turbinate, which almost no other dinosaurs are known to possess. Yet modern birds have them, as do modern mammals.

The structures are thin, curled surfaces within the nose that increase the surface area for blood and air to exchange heat.

Dr Tada says Triceratops probably wasn’t fully warm-blooded, but the researchers believe the structures helped keep temperature and moisture levels under control as its large skull would be difficult to cool down otherwise.“Although we’re not 100% sure Triceratops had a respiratory turbinate, as most other dinosaurs don’t, some birds have an attachment base (ridge) for the turbinate. Horned dinosaurs have a similar ridge at the similar location in their nose as well. Triceratops Had Huge Nose to Control its Body Temperature, Suggests Curious Scientis

Multiple Types of Plastic Are Turned into Vinegar Using Sunlight-Powered Process Without Emissions

Researchers at the University of Waterloo have discovered a way to turn plastic waste into acetic acid, the main ingredient of vinegar, using sunlight.

The breakthrough offers a promising new approach to reducing plastic pollution through photocatalysis, while simultaneously creating a useful, value-added chemical product through a process inspired by nature.

“Our goal was to solve the plastic pollution challenge by converting microplastic waste into high-value products using sunlight,” said Dr. Yimin Wu, a professor of mechanical and mechatronics engineering at the University of Waterloo, Canada.

Plastic waste, notably microplastics, has been found across many of the planet’s ecosystems, raising concerns about threats to terrestrial and marine life as well as human health. Plastic recycling rates remain low around the globe.

To tackle this problem, the team developed a bio-inspired photocatalysis process using iron atoms embedded in carbon nitride, a way that certain types of fungi break down organic matter using enzymes.

When exposed to sunlight, the material drives a series of chemical reactions that transform plastic polymers into acetic acid with high selectivity. The reaction takes place in water, making it particularly relevant for addressing plastic pollution in aquatic environments.

Acetic acid is widely used in food production, chemical manufacturing and energy applications. The study shows it can be produced from common plastic wastes, including PVC, PP, PE and PET, and remains effective across mixed plastic compositions.

This makes the approach well suited to real-world waste streams, offering a promising alternative to plastic incineration, and could support more circular approaches to material use while providing a new strategy for upcycling plastics.

“Both from a business and societal perspective, the financial and economic benefits associated with this innovation seem promising,” said Roy Brouwer, executive director of the Water Institute and a coauthor of the article supporting the techno-economic analysis.

“This method allows abundant and free solar energy to break down plastic pollution without adding extra carbon dioxide to the atmosphere,” Wu adds.

The findings also point to new possibilities for addressing microplastics directly. Because the process degrades plastics at the chemical level, it could help prevent the accumulation of microplastics in water systems.While still at the laboratory stage, the team envisions that this approach could be adapted for scalable, solar-driven recycling and environmental cleanup and the photocatalytic upcycling system can be further enhanced through strategic engineering of the materials and manufacturing processes.
