⭐⭐⭐⭐.5/5, rounding up to 5⭐ "Jurrasic" Jemma Thorne is an Palentologist and head of Geology at Swanbourne University and is well known in her field. Jemma is walking her dog Dino on the beach one morning when they find a complete Plesiosaurus skeleton and manage to unearth it. However depite being the largest skeleton ever found it seems that the skeleton is not good luck as everywhere Jemma goes, someone is trying to kill her. I very much enjoyed that Jemma was a "real character." She was written as a strong, smart individual and remained so for the entire book. Unlike many books that have their female characters making crazy dumb choices, Jemma did her best to be mindful of her actions. There were a few times when her heart overrulled her head, but that happens to the best of us. Jemma, as a character, is also strongly adversely affected when two people close to her die, one of which she believes she is indirectly responsible. Jemma becomes depressed and angry, lashing out at those arlund her and isolating herself. These are real emotional actions that are missing from many thrillers. Delaney did a great job writing a woman who we could empathize with and also look up to. This is a debut indie novel that is being turned into a series and i cannot wait to continue it.

    ***Contains Spoilers****

    A Dangerous Fossil started off as a bit of a slow burn and did contain slow chunks throughout it, but overall was enjoyable. I wanted there to be a connection though between the stolker and the theft and was disappointed when they were completely unrelated. It felt a little unnecessary. I also wished Sally had played a bigger role instead of just the irritating coworker. But the mother/daughter dynamic was great to see develop and I hope we will see that continue in book 2.

    A Dangerous Fossil: A Jurasssic Jemma Mystery by John J. Delaney

    On an English coast, main character Jemma Thorne unearths a massive plesiosaur fossil. As in, the entire skeleton! A huge discovery for her as it will help her to keep the local museum from being bought out and replaced. But…there are some plot twists in the story involving that fossil. Theft, murder, police investigations, and love affairs to name a few. The characters were likable and well developed, and the story flowed perfectly. This isn’t my usual genre choice of book, but I really enjoyed it and how fast-paced it was. Jemma is one clever lady! I definitely recommend this one to anyone who enjoys a good mystery!

    After uncovering a once in a lifetime fossil at the beach, events unfold one after another, becoming clear they are not coincidences. Enjoyed the read, however there was too much telling and not enough showing. At times, lost my attention and didn't keep me emersed in the storyline.

    5.0 out of 5 stars Cozy mystery filled with layers of enigmas to unravel
    Reviewed in the United States on December 15, 2022

    John J. Delaney’s murder mystery, A Dangerous Fossil (a Jurassic Jemma Mystery), is set in the small coastal town of Lulcombe, England where two-hundred-year-old seams of fossil-filled rocks from the early Jurassic period attract fossil hunters and tourists. When native-born, 43-year-old Jemma Thorne and her Springer Spaniel, Dino, head out to scour the beach for fossils following a storm, she has no idea how it will change her life.

    Dressed in heavy boots and a long-waxed coat she steps out into the dark of a windy, rainy early morning with her rucksack, dog, and hopes of beating the local fossil hunters to what the waves have kicked up on shore. Dino’s barking draws her attention to a large section of cliff that slipped during the storm, and Jemma makes a lifetime discovery. A plesiosaur skull. And it gets better. The whole skeleton is preserved. And it is huge. A major find. “Jurassic Jemma” is excited. Not only will it put Lulcombe on the map but it will also save the museum from being bought out and replaced by a large development that would ruin the sleepy little town. But time is not on her side. The tide is rising.

    This cozy mystery murder takes place in the museum. Delaney masterfully weaves a tangle of complicated relationships linking several people with possible motives in this entertaining whodunit. Jemma’s independent lifestyle becomes cramped with surveillance. All she wants is her independence back. When the police can’t come up with answers, Jemma makes a plan of her own. It puts her life at risk, but she’s willing to take the chance if she can get her life back and, if she’s lucky, get “Plessie” back in the process.

    A Dangerous Fossil features a strong independent female protagonist in Jemma Thorne. Fossils are her passion and her home life as a divorced, single mom with a college-aged daughter and detective boyfriend let her personality, independence, strengths, and weaknesses shine. I recommend this page-turner to fans of cozy mysteries, detective novels, and soft-boiled mysteries. If you enjoyed reading the Ruth Galloway series by Elly Griffiths or Duncan Kincaid/Gemma James series by Deborah Crombie, this book is for you. Delaney provides plenty of neatly packaged clues for readers to follow. A Dangerous Fossil is a five-star cozy mystery winner filled with layers of enigmas and secrets ready to be unraveled.

    I am KICKING myself for not reading this book sooner. I was hooked from the very beginning. I had absolutely no idea what direction the book was going to go take, and every twist brought me in more and more! I have never read a book like this before, combining crime with fossils! The research into palaeontology and geology is so obvious, which made me love it even more!

    At 363 pages long, this took me just under 4 hours to read. I highly recommend this, and as at the time I’m writing this review - I’ve almost finished book 2!

    This was a different story to what I normally read. More cozy rather than hardboiled.
    John has got the touch and he writes the story at an easy pace so despite being a mystery thriller, as a reader I never felt pressurised to speed up. Uncanny but sure shot was the way the story progressed.
    The action was controlled and the reactions of the characters spot on.
    Jemma seems like a dear and I would like to read more about her.

    4.0 out of 5 stars If you like the Ruth Galloway series by Elly Griffiths , I think you'll like this
    Reviewed in the United Kingdom on January 24, 2023
    Format: KindleVerified Purchase
    I am a big fan of the Ruth Galloway series so this book seemed right up my alley. History and science and mystery, and in an interesting location.

    I will admit that on the first attempt,  I didn't make it past the first chapters.  That's not unusual for me though - I read a lot of books and sometimes it can depend on my mood whether a book grabs me from the start. I was interested enough to give this one another try though, and I'm very glad I did. On the second attempt,  I just tore through it and was reluctant to put it down.

    The highlights for me were the quality of the writing, which was really good and confident, some interesting subplots, and some nice little touches that I hadn’t come across before – I remember thinking the trick with the drone was very clever! The story flows very well, and really holds the attention.

    The only reason I took away a star is that, for me personally at least, some of the scenes and characters felt either superfluous to the story or just not believable. It seemed to be mainly the ‘badies’ or potential ‘badies’. And I think it only stood out because the other characters were well rounded , and we saw them flaws and all, whereas a few just seemed like caricatures of meanness. It’s only a minor quibble though and didn’t take away from my overall enjoyment.

    I sincerely hope that this is only the first in a new series that I can get stuck into. I love when I come across a new book or series of this quality and I am really looking forward to learning more about the work of a fossil hunter, and to soaking up more of the atmosphere and history of Dorset’s Jurassic coast.
