Love in the Age of Trilobites (A Guide to Palaeozoic Relationships)

Valentines Day – Romance Among the Trilobites

As Valentine’s Day approaches, many people’s thoughts turn to those of romance. Whether romantically inclined or not, what with the outpouring of ads for flowers, cards and chocolates it’s hard to fail to notice the upcoming happy day that will see bunches of flowers sent and a box of chocolates is

However, for the palaeontologist this time of the year may be the appropriate time to reflect on the mysteries around such as prehistoric creatures with leviathans from the past – the dinosaurs, managed to find a partner and creation. One thing is for sure, dinosaurs and prehistoric animals in common with every other creature on the planet were able to breed and reproduce. These are extremely successful animals, many species from the past may be extinct now, with no surviving offspring but it is worth remembering that they were once highly successful. Take Trilobites for example, first found in Cambrian strata, the last of which became extinct around 250 million years ago. The superstars of the Mesozoic, the dinosaurs may be familiar to every student on earth. Animals like Tyrannosaurus rex may be more familiar to some students than the existing megafauna of animals that lived in places like the northern latitudes of Russia. How did dinosaurs naturally manage to reproduce and what strategies did they use to protect the eggs they laid and how did they take care of their young, these are the questions that have puzzled scientists. many years. Surprisingly, when you think that all we have to go on are a few fossilized bones, the answers to these questions and many others as they are a slowly and surely.

Sir David Attenborough, the highly respected author and presenter of the BBC history series, has been a lifelong collector of fossils. He had a fondness for them, and would fondly recall long summer days from his childhood when he would ride his bicycle from his home to a local quarry with exposed Jurassic sediments, to search for Ammonites and Brachiopods. When you remember you can just tell him the story of how he was tricked by a clever Moroccan seller on the purchase of a Trilobite fossil that he loves. the Atlas Mountains are famous for their best Trilobite fossils. Trilobites are an extinct group of aquatic arthropods. Our bodies are armored and have three distinct parts – hence their name.

Desperate to get a specimen for his own fossil collection, Sir David tries to negotiate with a dealer in the hope of driving up the price. You call to see a “very special fossil”, one that is sure to be extremely rare and personally very expensive. The fossil consists of a pair of Trilobites, which were cleaned in a pose that indicates that these poor invertebrates had their fate in the time of fusion. The interesting thing about this fossil, along with a Trilobite on the second specimen, of Sir David, is simply the horror of what you see. After a long period of haggling, customary in that part of the world, Sir David became the proud owner of a part of the fossil record that showed the breeding of two Trilobites.

Fake Fossils

Whether he had suffered from too much desert sun, or whether he had been carried away with the joy of seeing such wonderfully preserved fossils, it is difficult to say. It was later in the car that took him away from the small town from where he bought the valuable specimen that he began to think about this fossil and what it actually represented.

Trilobites as arthropods, is an extremely successful phylum. They are divided into at least nine major orders by scientists, similar in their diversity, distribution and evolutionary life. However, it is highly unlikely that any of their myriad forms were actually created by physical contact. As with many members of the Arthropoda today, marine animals such as crabs, lobsters and other crustaceans, the females would have produced the eggs, which had been outside their bodies and the males would have fertilized them – outside as it were. There was no need for a pair of these Trilobites to get, no love among Palaeozoic invertebrate animals, certainly no more than we see today in the reproductive habits of spiders and horseshoe crabs.

When Sir David took a closer look at the fossil, he realized that the specimen was not one but actually two. Each of the Trilobites has been cleverly glued into place, the whole diorama is nothing more than a superior creation, but a completely imagined game of a complex fossil preparation specialist. The purpose of this design is not to surprise the area of ​​science showing evidence of internal reproduction among Arthropods, although sophisticated ones like Trilobites. The reason is much more, why bother to sell two pieces when they can be stuck together to make a “special” fossil to fool a foolish tourist.

Poor Sir David, it speaks volumes for his self-deprecating nature that he is happy to tell this story, at a time when he is turning out to part with hard-earned money for something that is completely owned by a fossil expert. a community. However, instead of having pride of place in your fossil collection, I believe that particular item has been firmly “retired” and is now tucked away in a basement far from the eyes of any curious visitors who might visit and ask about your fossil collection.

Something as certain as the Trilobite external fusion, we bet that there are many more such “special” fossils that live in other people’s collections – fake fossils, carefully and intelligently put together to give the impression of passionate conflict from 300 years ago.

It turns out that this particular fossil, is not a testament to the reproductive processes of an invertebrate, but a testament to the subtleties and wisdom of a type of vertebrate, the skill in extracting resources from pieces of fossilized organic remains seems to know. there is no border.
