The First Dinosaur by Ian Lendler

The First Dinosaur tells the remarkable story of how scholars and scientists came to unravel the mystery of ancient life on Earth and to discover the dinosaur. The First Dinosaur traces the journey, step by step by telling the story of how the first four bones of the first dinosaur, Megalosaurus were found and ended up as part of a collection of fifteen bones in total. But within that story are multiple other stories of men and one woman who worked tirelessly to unravel the story of the Earth's past.

The Megalosaurus story begins with the discovery of a bone, two feet long and weighing twenty pounds by workers in a quarry in Oxfordshire, England in 1676. Dr. Plot, a chemistry professor at Oxford University, did not know that he was looking at the bone from an extinct animal that was in fact the first dinosaur, Megalosaurus. At this time, no one knew that reptiles of enormous size once roamed the Earth. The remains of animals, dug up out of quarries weren't really understood. They were called "formed stones" and people did not know where they came from, what they were or how they were formed.

To try to understand what he was given, Plot compared his bone with that of an elephant and saw that it was much larger. He believed it may have come from a race of giant humans. What he did do was record his observations for future scientists, measuring, describing and drawing the unusual bone in his book, The Natural History of Oxfordshire. 

In 1666, an enormous white shark was caught by fisherman in the Mediterranean Sea. Florence had become a learning center of science, so the Grand Duke of the city ordered it to be brought to his city. The Grand Duke Ferdinand de' Medici had created the Accademia del Cimento or "school of experiments" in 1657. It was the beginning of the Scientific Revolution and Florence was the center of new scientific endeavours. It embodied new way of thinking about the world. Previously "many European scholars believed that all human knowledge was contained in a few books, such as the Holy Bible." The students and professors of the Accademia  were the first to use Galileo's scientific method of observing and questioning.

Nicolaus Steno, a master dissectionist who dissected human cadavers to learn the secrets of the human body, was invited by Grand Duke Ferdinand to the Accademia. Steno, in his dissection of the shark head, noted that the teeth in the shark were similar to the "tongue stones" found by the thousands in Malta. In his book about the shark dissection, Steno wrote that the tongue stones were shark teeth, connecting the living animal with the remains of once living animals in the ground. He was the first to determine WHAT fossils are - the remains of animals and plants. And in fact, we now know that "tongue stones" are teeth from megalodons, giant prehistoric sharks that lived millions of years ago.

Robert Hooke, a scientist who improved many instruments such as the microscope, read Steno's book and was fascinated. Hooke was the first person to apply the scientific method by working in a laboratory and running experiments.  Hooke published a book, Micrographia, of his drawings of the natural world as seen through the microscope. His observations led him to theorize that fossils or "formed stones" might be the result of a process he called "Petrifaction".

In seventeenth century Europe and England, the idea of extinction, that entire species of animals and plants could die out was not considered possible. This was because the Bible was taken literally and it was thought that all the animals currently alive on the Earth had been there from the beginning of a world that was believed to be 6000 years old. However, Hooke, through his studies of fossils, began to consider the possibility that the past might look very different from the present and that fossils were the clue to helping understand the past. 

Collecting fossils was a pastime of the aristocrats that had begun several hundred years earlier. These fossils became a type of entertainment kept in a "cabinet of curiosities". Eventually a large museum, the Ashmolean Museum, housing a huge collection of fossils and "curiosities" opened at Oxford University and was overseen by Dr. Plot. The fascination with fossils created a booming industry in which fossils were dug up and sold by quarry workers in Oxford.

In 1699, Dr. Edward Llwyd saw a large tooth for sale in the window of a quarry worker's house in Stonesfield, a small town outside of Oxford. The quarries in this area were rich with fossils and this fossil tooth was different - it was the type of tooth used to rip flesh. It was in fact, the second Megalosaurus fossil and it came to be stored at the Ashmolean Museum. 

At this time many scientists were struggling to understand what was called "the Seashell Problem". Many fossilized fish skeletons and sea shells were found in rocks well above sea level, in mountains and even deserts. How could this be? To solve the seashell problem scientists needed to understand "Where do fossils come from?" and "Why are they found where they are?" Nicolas Steno in searching for answers to these questions went to Malta where the tongue stones were found and through observation developed what came to be known as Steno's First Law of Super-Position: "...rocks form in flat layers on top of one another." This meant that the oldest rocks formed the bottom layers. So how to account for younger rocks that contained seashells?

To answer these questions meant that scientists had to reconsider the time frame of the Earth. In the early 1700's calculations by James Ussher, an archbishop of the Church of Ireland determined that the Earth was formed on Sunday, October 23, 4004 B.C. But more and more, the evidence in the rocks did not support the biblical view of life on Earth. Scholars had turned to the Bible for answers and believed that Noah's Flood was the explanation.  However, some scholars began to think differently and offered strange and unusual theories to explain the seashell problem. 

By this time, the third fossil unknowingly belonging to the Megalosaurus was purchased by Sir Christopher Pegge. It was a large jawbone with some intact teeth and it too ended up in the Ashmolean Museum.

The next major development came with the birth of the Industrial Revolution and the use of coal to run factories. With the construction of canals to transport coal to factories in the cities, William Smith, an engineer was able to map the layers of rock that were exposed with each excavation. Smith came to recognize the same layers or strata as he called them, that he had noticed during his work in the Mearns Pit coal mine. Smith began mapping the strata all over England using the fossils he found in each layer and eventually created a geological map of England. This process took him 14 years. The importance of Smith's work is that he "understood that the strata and their fossils were telling a story" of the past in England.

Each new discovery simply generated more questions: "Why did each strata start and stop?...What causes these eras to come to an end?...What happened to the animals who were alive when the end came?..." From this point on, Lendler follows the story into France where revolution let to drastic social change and new ideas about the natural world. One key idea was proposed by renowned scientist Georges Culvier: life on Earth experienced extinctions on a catastrophic scale.

As more fossils were discovered, scientists began to realize the world was much older than they had ever thought, and that there was a world before humans and before that a world even before mammals. William Buckland, Mary Anning, Gideon Mantell, Richard Owen and Charles Lyell would all work in their own way to change forever how we think about the past.

It would be Culvier, with his brilliant ability to identify a collection of fifteen bones at the Ashmolean Museum, as a new type of land reptile that had never been seen before. This was the Megalosaurus. The discovery would be William Buckland's to announce to the scientific community. The age of dinosaurs had begun again....

Discussion

The First Dinosaur is detailed and fascinating account of how scientists came to discover dinosaurs. To do so required a monumental shift in how scientists viewed our world and our place in the world and how we viewed the past. 

Ian Lendler takes readers on a 200 year journey from the first known discovery of what would eventually be identified as a dinosaur bone to the coining of the word "dinosaur" by Richard Owen and and exhibition of the first dinosaurs at the Crystal Palace in London. Along this journey, young readers will meet many of the major players, who not only worked long arduous hours searching for fossils, but who often struggled for years to have their efforts recognized. In some cases, such as Mary Anning, their contributions would take centuries to be recognized. 

His portrayal of the main players offers interesting perspectives on characters such as William Buckland, Gideon Mantell, Richard Owen and Mary Anning. Young readers will find each person comes alive on the pages of The First Dinosaur. There is William Buckland whose over-the-top personality  included eating every kind of animal he could find. Gideon Mantell whose obsession with fossils saw him lose both money and family while making fantastic contributions to science. Richard Owen whose hatred of Mantell led him to actively work against this good man even after Mantell's death. And Mary Anning who discovered three of the dinosaurs on exhibit at the Crystal Palace but whose enormous contributions to paleontology went unrecognized for 200 years. Lendler also touches on the relationships many of these men had with one another and how the class structure in England influenced scientific endeavours.

One of the more interesting aspects Lendler features is the move away from a biblical perspective that early geologists and paleontologists had to make. In the seventeenth century man's place in the cosmos was based heavily on what was taught in the Bible. But the Bible is not a scientific work but rather an account of man's relationship with God. This was not the view of the Bible in the seventeenth century because it was considered a history of the world with the most important events recorded. Galileo was the first to challenge the way man would think about himself in the universe. For many scientists such as Richard Owen, there was no reconciling the biblical version with these new ideas. For others like William Buckland, who spent his life trying to prove Noah's flood, the new ideas prevailed.

Lendler touches on the effects revolutions played in the discovery of dinosaurs, including the Scientific Revolution, the French Revolution and the Industrial Revolution. He shows how these revolutions changed society and brought about different ways of thinking.

While there is a much detail in this book that might bog down younger readers, Lendler entices his readers with plenty of interesting photographs, illustrations done in pen, ink and digital medium and sidebars of information. There is a Bibliography, an Index, and Lendler includes an Epilogue which tells what happened to the major players in the quest for the first dinosaur. The First Dinosaur is a must read for those who are interested in dinosaurs and the past.
