The belief that plastic dinosaurs are made from the byproducts of real dinosaurs is a fun idea, but it is not true. Fossil fuels, which are used to make plastic, are derived from ancient organic material, but not from dinosaurs. The misconception likely stems from the association between the words fossil and dinosaur, and the use of dinosaur imagery in advertising by oil companies like Sinclair Oil in the 1930s. In reality, fossil fuels are formed from the remains of microscopic organisms like phytoplankton and microalgae, which lived in the ocean millions of years ago.

Plastic is a form of biomass, made from petroleum
Plastic dinosaurs are not minerals, but they do contain fossil fuels, which are made from the remains of ancient organisms. Most oil comes from ocean life buried on the seabed, and while some of this may have come from dinosaurs, it is mostly made up of plants and other aquatic organisms.
Plastic is a human-made polymer derived from petroleum, a fossil fuel created by biomass. Petroleum is made from aquatic phytoplankton and zooplankton, and as such, plastic is considered a form of biomass. The process of creating plastic involves extracting and refining crude oil and natural gas to yield useful chemicals, including "monomers" (molecules that are the basic building blocks of polymers). These monomers are then converted into higher molecular weight hydrocarbons (polymers) through a process called polymerisation.
Bioplastics are a type of plastic made from renewable biomass sources such as corn starch, rice starch, cellulose, and soy protein. They were the first plastics to be created, historically, but they have been largely superseded by fossil-fuel plastics derived from petroleum or natural gas. However, with increasing scrutiny on fossil-based plastics, bioplastics are gaining interest again. Bioplastics have the advantage of being independent of fossil fuels, which are finite resources with environmental impacts. They can also have a lower carbon footprint than their fossil counterparts, especially when biomass is used as a raw material.
That being said, not all bioplastics are more sustainable than fossil-based plastics. Some bioplastic processes result in a higher carbon footprint, and the biodegradability of bioplastics depends on their molecular structure and the environmental conditions. For example, PLA is a biodegradable bioplastic, but it may not biodegrade in all climates. Additionally, the difficulty of performing injection moulding with PLA often results in the use of petroleum-based chemical additives, which can contaminate the existing plastic recycling stream.
Overall, while plastic is a form of biomass made from petroleum, the specific type of plastic and its method of production play a significant role in determining its environmental impact.

Fossil fuels are organic material, but not fossils
Fossil fuels are indeed organic materials, but they are not fossils. The term "fossil fuel" is a misnomer that has caught on and is still widely used. Fossil fuels include coal, petroleum (oil), natural gas, oil shales, bitumens, and tar sands and heavy oils. They are formed from the remains of organic matter produced by photosynthesis, where green plants and certain other organisms transform light energy into chemical energy.
The process of converting organic materials into fossil fuels typically takes millions of years of geological processes. Aquatic phytoplankton and zooplankton that died and sedimented in large quantities under anoxic conditions began forming petroleum and natural gas through anaerobic decomposition. Over time, the organic matter chemically altered into a waxy substance called kerogen, which further transformed into liquid and gaseous hydrocarbons.
While fossil fuels originate from organic matter, they are not derived from fossils or dinosaur bones. Most of the fossil fuel material we use today comes from algae, bacteria, and plants, some of which date back to the Devonian Period, 419.2 million to 358.9 million years ago. The world's coal deposits, for example, were formed about 300 million years ago, long before the evolution of dinosaurs.
Additionally, the idea that fossil fuels are not derived from ancient organic matter has been proposed. This theory suggests that hydrocarbons could form from chemical reactions deep inside the Earth, rather than from the decomposition of organic matter. While this concept has gained some support, it has not yet reached mainstream acceptance, and more research is needed to explore the synthesis and stability of these compounds.
In conclusion, while fossil fuels are indeed organic materials, they are not fossils in the traditional sense of the word. The term "fossil fuel" is a misnomer, and these fuels are primarily derived from ancient organic matter such as algae, bacteria, and plants, rather than dinosaur fossils or bones.

Oil is derived from ancient living things
The leading theory on the origin of oil is the "biogenic theory", which states that oil comes from the remains of tiny organisms like bacteria, plankton, and algae. These organisms lived millions of years ago and, over time, their remains were transformed by heat and pressure into the oil we use today. This process, known as petroleum formation, can take anywhere from 1 million to 1 billion years. While the exact chemical transformation is not fully understood, we know that the organic material is broken down into smaller molecules composed of carbon and hydrogen atoms, which then become either petroleum or natural gas depending on the liquid or gaseous state of the mixture.
This theory is supported by the fact that oil is often found in sedimentary rocks, which are formed by the accumulation of organic material and sediment over time. However, there is also evidence of oil reservoirs in non-sedimentary rocks, which has led to the development of the "abiogenic" theory of petroleum origin. This hypothesis proposes that some of the earth's petroleum and natural gas deposits were formed inorganically, without the involvement of ancient living things.
While the exact contribution of abiogenic sources to the earth's oil reserves is still debated, it is clear that the majority of our oil does come from ancient living things, even if they are not dinosaurs. The idea that oil comes from dinosaurs is a poetic notion, but in reality, most of our oil comes from the remains of tiny organisms that lived long before the dinosaurs evolved.
So, while a plastic dinosaur toy may contain a small amount of oil derived from ancient living things, it is important to remember that the oil itself is not directly from dinosaurs. The complex hydrocarbons that make up plastic have a long and intricate history, and the story of their formation is one that geologists are still working to understand.

Sinclair Oil's dinosaur logo perpetuated the myth
The Sinclair Oil Corporation was an American petroleum corporation founded by Harry F. Sinclair on 1 May 1916. The corporate logo featured the silhouette of a large green Brontosaurus dinosaur, based on the then-common idea that oil deposits beneath the earth came from the dead bodies of dinosaurs. Sinclair's advertising writers first had the idea to use dinosaurs in Sinclair marketing back in 1930. They were promoting lubricants refined from crude oil believed to have been formed when dinosaurs roamed the earth. The original campaign included a dozen different dinosaurs, but it was the gentle giant, the Apatosaurus, that captured the hearts of Americans. The use of the dinosaur logo and mascot, an Apatosaurus, perpetuated the myth that oil deposits beneath the earth came from dinosaurs. This myth was further perpetuated by Sinclair's sponsorship of dinosaur exhibits at the Chicago World's Fair in 1933-1934 and the New York World's Fair in 1964-1965. These exhibits, known as "Dinoland", featured life-size replicas of dinosaurs, including a 2-ton animated model of a Brontosaurus. Sinclair also marketed a line of rubber Brontosaurs with wiggling heads and tails, as well as inflatable dinosaurs, further associating their brand with dinosaurs.
The connection between Sinclair Oil and dinosaurs can also be traced back to the paleontologist Barnum Brown, who authored promotional materials for the company in exchange for funding for his dinosaur fossil expeditions. This mutually beneficial arrangement helped to solidify the link between dinosaurs and oil in the public imagination.
It is important to note that the idea that oil comes from dinosaurs is a myth. Most scientists agree that petroleum is formed from the fossils of plants and tiny marine organisms, not dinosaur fossils. Despite this, the association between Sinclair Oil and dinosaurs, perpetuated through advertising and exhibits, has left a lasting impact on popular culture, as evidenced by the continued appearance of the Sinclair dinosaur, "Dino", at events like the Macy's Thanksgiving Day Parade.

Water in the ocean has been part of a dinosaur
Water dinosaurs, or marine reptiles, lived during the Mesozoic era. These were not dinosaurs in the traditional sense but were a diverse group of marine creatures that inhabited the oceans, rivers, and lakes. They were found in various parts of the world, including North America, North Africa, China, and Germany. Some preferred shallow waters, while others lived in deeper waters. Some species were adapted to swim in freshwater, while others inhabited saltwater environments.
The term "sea dinosaurs" is misleading. Dinosaurs, as we typically define them, were land-dwelling creatures. However, some dinosaurs inhabited coastal areas and may have even swum from time to time. Spinosaurus, for example, lived in humid environments near water and is believed to have been a water-loving dinosaur. It had several unique features, including a long, crocodile-like snout and powerful arms with sharp claws. Other dinosaurs, like the Saltasaurus loricatus, were once believed to remain in the water to support their body weight, but this theory has been disproven.
The water dinosaurs were a fascinating group of marine reptiles, including the plesiosaurs, ichthyosaurs, and mosasaurs. Plesiosaurs had a small head, a long neck, and a turtle-like body. Ichthyosaurs, or 'fish lizards' in Ancient Greek, were diverse, with some living in coastal waters and others in the deepest parts of the ocean. Mosasaurs were large predators with long, slender bodies, paddle-like limbs, and a powerful tail.
The water cycle has always circulated the planet, and it is possible that the water in the ocean today has been part of a dinosaur. Water that doesn't flow into lakes or rivers seeps through the surface of the Earth, and can get absorbed by plants or fall deeper into the ground until it reaches natural storage areas called aquifers. This water, often referred to as 'hard water', tends to collect extra minerals on its journey through the Earth. So, the water in your glass may be the same water that dinosaurs drank about 65 million years ago.

Frequently asked questions
No, a plastic dinosaur is not a mineral. Plastic is not considered a mineral because it is a synthetic, man-made material and not naturally occurring, which is a key requirement for a substance to be classified as a mineral.
Minerals are naturally occurring substances that are inorganic and have a definite chemical composition and a characteristic crystalline structure.
Some examples of minerals include quartz, which forms through natural geological processes and has a consistent chemical structure.
