“Rock Removal is About to Get a Lot Easier!”

 


When a fossil is found in the rock, paleontologists don’t actually just dig the fossil itself out of the rock but they remove it along with a block of the surrounding rock, called matrix, to later be prepared further in the lab. Like this 4 million year old ?Macoma sp. clam you see here, the matrix needs to be carefully cut back or completely removed, depending upon the fragility of the fossil.  Here you see traditional hand pick removal of the matrix, which fine-tunes the block for later compact storage in a public museum!  That method is about to be augmented with pneumatic help.

With our new small business development grant I’ll be purchasing two new air scribes; the “Velociraptor Mark II” and the “T. rex” from Zoic Palaeotech.  I’ve wanted air scribes for quite awhile, but have never been able to afford them for prep work until now!  Looking forward to upping my prep game now that my business is off the ground.

“A Good Week for Business, and More”

 


I am pleased to announce that “Pacific Paleontology”, our new paleontological mitigation venture, has been chosen to receive a $5000.00 U.S. Small Business Administration Dream Fund Grant! The grant will be used to buy essential equipment that is needed to effectively preserve and archive fossil discoveries made at local construction sites here in Santa Cruz and Monterey Counties! 

And on a related note, Pacific Paleontology received its first contract this week to monitor a small subdivision project right here in Scotts Valley, Santa Cruz County! The site is literally right around the corner from our house and will be excavating down into the very same layer of rock that got me involved in paleontology all those decades ago as a boy roaming the hills around my home; the Santa Margarita Formation. This layer of unconsolidated sands and gravels is widespread throughout central and southern California and hosts an extremely rich and well-known Miocene (12-15mya) marine fauna. I am looking forward to pinning that first dollar bill in my prep lab very soon! 

And in other related news I have been invited to the Digitization Academy with iDigBio as the Paleontological Collections Advisor for the Santa Cruz Museum of Natural History. There is a big push today in natural history museums to make their collections available digitally on the web for the wider scientific community to access. My classmates come from institutions in a global community; Africa, South America, Europe, etc., who are making natural history collections available worldwide. So researchers from anywhere in the world who would like to study the fossils in our museum’s collections can login to see photos and other data on the specimens representing the evolutionary history of life in the Monterey Bay! It really is phenomenally exciting to be a part of helping to make that piece happen for our museum and our community.  Super exciting!

“The Megalodons of Calakmul”

 

This Megalodon jaw reconstruction here, very well-done by the way, as well as a host of other well-reconstructed extinct species discovered from the area, including this Gomphotherium, are to be found at the Museo de Naturaleza y Arqueologia de Calakmul, Calakmul, Campeche, MX.  Susan and I literally stumbled upon this extremely well-done little museum in the middle of the Mayan jungle isolated from any other towns on our honeymoon ten years ago.  Calakmul, a biosphere reserve now, is the name of the newly discovered ancient Mayan city that once existed here.  It would have been about 7.7 square miles in area with 6,250 structures discovered so far!  The base of the great pyramid covers almost 5 acres, making it the largest Mayan construction in existence and while we were there it was actively being explored by researchers! It is a UNESCO World Heritage Site and you can read more here for a good general introduction to this incredible recent archeological discovery.

The Lost World: A Boyhood Home in Scotts Valley, CA

A peek inside at my upcoming book by the same title, volume on adds to the experience.  My family and I built an amusement park named “The Lost World” in Scotts Valley, CA.  My father, Larry Thompson, mother Peggy, and grandparents William and Florence Thompson, helped design and build the park around Axel Erlandson's "Tree Circus", a completely unique grove of grafted trees.  In Scotts Valley, my father met Axel, originally a bean farmer from Turlock, CA, who had moved himself and his trees to the town several years before.  Then in his 70's, Axel wanted to sell the trees and my dad purchased them to continue Axel’s legacy.  My dad tended to the trees, making upgrades to the pathways and added a creek and waterfall, while Axel relaxed and watched the Lost World park grow up around his creations.  Because the new Hwy 17 bypass skirted around Scotts Valley Dr. shortly after we purchased the trees, our main avenue of customer traffic was cut off.  My dad needed a way to attract visitors back to the growing park.  Being influenced by Sir Arthur Conan Doyle’s original film “The Lost World” (1925) he then created "Dinosaur Land", where dozens of huge life-size animatronic dinosaurs lived and could be seen from the new freeway, attracting visitors from San Jose going to the Boardwalk back around to our park.  My dad died when I was 5, and only a year after opening his park, in 1965.  I then grew up, until I went away to college, in Axel Erlandson's "Castle" that he built in the park (seen in the photos)  amongst the incredible forest of grafted trees and families of life-sized dinosaurs.  When I became old enough, I tended the trees and the dinosaurs too.  Not surprisingly, I became a paleontologist and a science teacher, now recently retired from teaching and creating a paleontology business of my own: “Pacific Paleontology” here in Santa Cruz and Monterey.  I have been writing a book on the history of our Lost World amusement park and Axel Erlandson’s Tree Circus and would welcome anyone sharing memories, photos, videos etc. to wthompsonctems@gmail.com or just txt to 831-535-8545.

Patterns & Processes in Rockfall Dynamics from 1977-2022

Since 1977 when I was 17 I have been fascinated by the dynamic nature of our coast here along the Monterey Bay.  I can never go down to the same shore twice; it’s in constant flux, never the same as it was the day before.  One of the things that I have been tracking as a paleontologist here are the rockfalls that are continually happening as a coastal erosional process.  These rockfalls are singularly amazing, not only in

their size and scope, but in the history of our bay that they reveal.  With each new fall, like turning the pages of a book, new information comes to light and a more complete picture of the history of our bay begins to form in my mind.  This process is a decadal revelation; only imaginable over long periods of time, with emergent information coming to light in the longer scale that is not visible from year to year.  Not year-to-

year; but more expansive time over 10-, 20-, 30-, and 40-years that allows one to understand geological time, Deep Time, better.  With each turn of the page, new and varied creatures are revealed that were not known before and more details of the ancient physical oceanography of the California coast emerges with each new strata set that comes to the light of day.  Interacting with a single place over a large expanse

of time such as this can engage one in processes that are not visible in the day to day.  There is a larger periodicity of non-random dynamic processes that overlies a place such as this.  Some of those processes present themselves to me, others may only be inferred over even larger expanses of time, not known to a single life span.  I will end with a quote from one of my favorite authors, Pulitzer Prize winning Wallace Stegner

who has written some of my most comforting literature on the American west.  I came to know Wallace, or rather his writing, through my father, who I did not really know at all in the sense of “father” since he past away when I was 5.  From a longing to know who my father was, I was introduced to Wallace, since my father and Wallace

grew up in the same small Canadian town together, Eastend, in the early 1900’s.  In reading the words of Stegner it allowed me to feel close to the father I never knew, and at the same time allowed me to learn an appreciation for a sense of place.  This is a quote from one of Wallace’s last essays, the year before he died at age 84; from “The

Sense of Place” by Wallace Stegner. Copyright 1992 by Wallace Stegner. Reprinted by permission of Random House, Inc. “So I must believe that, at least to human perception, a place is not a place until people have been born in it, have grown up in it, lived in it, known it, died in it – have both experienced and shaped it, as individuals, families, neighborhoods, and communities, over more than one generation. Some are born in their place, some find it, some realize after long searching that the place they left is the one they have been searching for. But whatever their relation to it, it is made a place only by slow accrual, like a coral reef.”  I hope you all have a strong sense of place, wherever that may be, however diversified, however tangible or conceptual. In this particular place on Earth I am comforted, because it recalls the work of Wallace Stegner, who in turn certainly knew my father, and by such circuitous routes I, too, can know my father.

Olivella's graveyard at Pandora's Cave!


Here is Olivella's Graveyard (now referred to the genus Callianax) at Pandora's Cave, New Brighton State Beach; the first shell bed unconformably overlying the finer sandstone layer immediately below it.  One can see here bivalves such as Leukoma and Macoma, a naticid, perhaps Natica clausa, and the Nassariids Demondia californicus and Nassarius.  Portions of this shell layer, which does not stretch continuously for the entire length of the section and is thus more aptly referred to as a Lag or Shell Bed or Lens, consists partly of concreted shell blobs and loosely concentrated shells in which the gastropods are preserved mostly whole and the bivalves are predominantly broken prior to burial.  Olivella's Graveyard represents a moderately shallow water (27-46m) storm deposit and is one of many dozens of examples of "missing time", or  unconformities, in the evolutionary record of our Monterey Bay where once-existing layers have been eroded away by storms during the Pliocene Period about 3 million years ago, never to be seen again.

Life's Perfect Circle...

 


I am happy to share that I’m adding a new position as Paleontology Collections Advisor at the Santa Cruz Museum of Natural History to my schedule! I officially began my career as a paleontologist with the museum 46 years ago now, in 1976 when I was 16. It brings me unparalleled joy to now be working with the museum once again, completing my life's circle with the original institution that I began with all those years ago. https://www.santacruzmuseum.org/
