Presumably a slow swimming grazer-detritivore. Alternative combination: Elonichthys cupidineus Lambe, 1916. Taxonomy according to fossilworks.org. Diagnosis for Albertonia according to Schaeffer and Mangus, 1976, pp. 545-548: "A parasemionotid (as defined by Patterson, 1973, pp. 262, 287) specialized in having deeply fusiform body and greatly elongated pectoral fins. Small acuminate marginal teeth present on mobile maxilla and dentary. Suspensorium nearly vertical. Preopercular present; opercular and subopercular subequal. Longest pectoral fm rays about one-half length of body. All fins bordered by fringing fulcra; fin rays distally segmented. Caudal fin hemiheterocercal, weakly cleft, and probably equilobate. Scales rhomboidal, deeper than wide in anterior flank region; posterior border of all scales pectinate.“ Quote from Schaeffer and Mangus, 1976, p. 548: “Albertonia cupidinia . . . is a deeply fusiform fish: the maximum body depth is about one-third of the overall length. The impressively elongated pectoral fins, composed of approximately 21 rays, are equal to about one-half of the total body length. The pelvic fins, which are very much smaller and include nine or 10 rays, are situated at the deepest part of the ventral contour. The dorsal fin, composed of about 17 rays, arises in front of the anal, which has approximately 18 rays. The short-lobed hemiheterocercal caudal fin is composed of about 30 principal rays and is externally homocercal. The scales are rhombic with serrated posterior borders. There are about 40 scale rows between the cleithrum and the origin of the hypochordal lobe of the caudal fin." Identified by Dr. N. Micklich (Hessisches Landesmuseum Darmstadt - HLMD).

BC Paleontology Educational Booth at the Cranbrook Rock & Lapidary Club Mineral, Fossil & Gem Show
BrennanThePaleoDude posted a topic in Partners in Paleontology - Member Contributions to Science
I was invited to set up an educational booth at the Cranbrook Rock & Lapidary Club's Mineral, Fossil & Gem Show in October. It was a huge hit with the local collectors and members of the public. I was able to chat with a diversity of people ranging from families to fanatics and even some familiar faces from social media swung by to say hi. I am excited for the next event and will definitely be spending more time in Cranbrook. Such a welcoming community of fossil hunters and great number of Cambrian sites. Here are some photos of my table display. I wanted to spice things up and add fossils from around the world for this event as well as feature some of my current work.- 8 replies

Cretaceous Porcelain Crab Petrolisthes landsendi new species Late Cretaceous (Comox/Haslam Formation) Saanich Peninsula, Vancouver Island, British Columbia, Canada Donated to the Royal British Columbia Museum, Victoria, BC https://www.researchgate.net/publication/347129633_A_new_species_of_Petrolisthes_STIMPSON_1858_Anomura_Porcellanidae_from_the_Upper_Cretaceous_upper_Santonian_of_Vancouver_Island_Canada It was determined that this fossil specimen collected by me and formerly residing in my collection was potentially a new species. After sending the specimen to Torrey Nyborg for examination, it was confirmed to be a new species of Porcelain crab from the late Cretaceous of Southern Vancouver Island. This new species was determined to be the "oldest species of Petrolisthes Stimpson, 1858 and is the first species from the northeastern Pacific".

Since the group was so helpful with this post, I thought I would ask again with a couple of rock finds from last week's fishing trip on the Flathead River in south eastern British Columbia. I found several rocks that looked like these two in the next three pics. This rock is about 12" long and the next two pics are the same rock from different angles. The "shards" in the rock caught my attention. Are they fossils? This is a different rock from the previous one, but it had the same type of shards. This next rock contains what appears to contain segmented worms, or cases. The first picture with the ruler is the rock face-on. The following two pics are of the rock from either end. Does this rock contain fossils? Thanks!

Hi Everyone, I was hoping that someone is good with odd bivalves here. I was searching around my favourite spot at Northwest Bay in the Nanaimo Group of Vancouver Island Canada. One of the spots is in a layer of very soft shale that erodes out onto the beach. I undercovered this fossil which I initially assumed was a pocket of young Inoceramus vancouverensis. This is very common in the Nanaimo Group, but not at this location. As I looked further I noticed elongated material that had a thin shell coating under the bivalve shells, Then I noticed the layer of coalified material between the shell and thin layer of shelly material. Could this be Martesia, the shipworm? As the fossil material is very flattened it takes a bit of imagination to figure out its shape in 3 D. Any help would be great!

Because it's only a short ferry ride away from the mainland, I often try to make a point to go to Vancouver Island when I have some time free, both to explore its natural beauty and to hunt for fossils in its rich and varied Cretaceous deposits. Much of the eastern coast of the island adjacent to the Strait of Georgia, as well as many of the smaller islands just offshore, are underlain by the Nanaimo Group - an ancient marine basin whose age extends from about 90 to 65 million years. Many of the shorelines, creeks, and quarries of Vancouver Island, where the formation crops out, can be explored for their fossil bounty. I've just come back from a solo camping trip a few weeks ago, where I spent most of my time exploring the abandoned shale pits east of Nanaimo. While this was the main purpose of the excursion, it also gave me a good reason to visit the Courtenay and District Museum to get some paperwork sorted to donate a fossil cycad seed I found on a previous trip (detailed here). That said, I'm going to cheat a little in this post, and also include some photos and finds from two previous trips - one earlier in the spring, and another from late last summer. Anyway, I hope you enjoy! First I'll start with some photos from the field.

Something that has been a long time coming... As I have no air tools for prepping fossils, I got the bee in my bonnet to try using bits of wood and glue to break away bits of matrix partially covering leaves from McAbee specimens that I collected years ago (before the gov't ban on collecting there). It worked pretty well on these few pieces I tried. The only difficulty came when the matrix to be removed was too thick and integrated with the surrounding matrix. Then it would only peel the thinnest layer off the top. Another round or rounds could eventually accomplish the task in this case, as I did in one instance. Glue used was Lepage's gel-type superglue. I let them cure for a half a day to a day before pulling. Soaking the stick in a jar of acetone frees the broken-off piece if wanting to retain it (as I did with the Ginkgo below). This could work on any number of similar fossils from e.g. Green River, etc. but I can't guarantee consistent results!

Blakeburn Amber (Allenby Fm., 52.5-48 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
“Blakeburn Amber” Coalmont, British Columbia Allenby Fm. (Princeton Group) 52.5-48 Ma Weight: 0.8g Dimensions: 16x16x13mm Lighting: Longwave UV The final entry in a series of ten, detailing various rare ambers from European, Asian, and North American localities. This is a fine example of an in-situ piece of amber. The matrix is high-volatile type B bituminous coal, which contains small portions of methane; it has a bright vitreous luster due to it containing over 90% vitrinite (a “maceral”, or component of coal, derived from woody plant tissue). Geology of the Allenby Fm.: Within the Tulameen Basin lies the Tulameen Coalfield, which covers approximately 6.2 square miles (10 sq. km.), and is located about 12.5 miles (20 km.) northwest of Princeton, B.C.; within the Allenby Fm. is three members/layers: an upper member of sandstone and conglomerate 600 m thick, a lower sandstone member 100-150 m thick, and a middle member 130 m thick; the middle member is predominantly mudstone and shale and contains two coal seams, the upper seam containing amber. The main seam lies 25-40 m above the lower seam, is 15-21 m thick, and is of much higher quality than the lower seam: it is from this layer that much of the mining was done. Botanical Source: Nearby, the Allenby Fm. is composed of three Members, the middle being the Vermillion Bluffs Shale: it is known for its rich deposits of plant fossils. Approximately 9.3 miles (15 km.) southeast of the Tulameen Coalfield, is the famous Thomas Ranch locality: here, the majority of the plant fossils consist of cupressaceous remains, “Metasequoia occidentalis” being the most common; at Tiger Mountain (Washington State, USA), Eocene-aged amber occurs alongside Metasequoia and Taxodium leaf imprints, which are plentiful. It is quite possible that Blakeburn and Tiger Mountain ambers were derived from a Cupressaceae source tree. History of Mine: In 1899, analyses on the coal of the Tulameen Basin were submitted to the Geological Survey of Canada, and mining began in 1904 in the Blakeburn Creek area; the owners of the mines, Coalmont Collieries, Ltd., created 5 mines over the next 30 years, with mines No. 1 and No. 2 opening in 1913. No. 3 and No. 4 began production in the 1920s, but were shut down in the 1930s due to fires and flooding. It was in the No. 4 mine that a tragic incident occurred on August 13, 1930: an explosion killed 45 men, and was believed to have been caused by a buildup of methane (released from the high-volatile type B coal, mentioned earlier) from closed-off mining areas. The official explanation by the mining company claimed methane was not a major contributing factor; interesting, considering that the fire bosses of the mine asserted to the workers beforehand that the mines were gas-free. From 1900 to 1940, 2.2 million tons of coal were produced, with the No. 5 Mine closing in 1940. Sporadic exploration has been done in the area since 1960, and in 2002, Compliance Coal Mining was planning to open a mine in the Tulameen Basin.

Hello all, I recently collected this interesting permineralized fruit from the Browns River on Vancouver Island, B.C. This river exposes outcrops of the lower Trent River formation of the Nanaimo Group, which represents a relatively nearshore Campanian marine environment. The fossil itself was found in an outcrop of fairly poorly consolidated sandstone, which also contained large pieces of coalified wood debris and a poorly preserved, crushed ammonite. I'm not particularly optimistic about getting a positive ID on this, but I am interested to see what others think about it, and would definitely appreciate some educated suggestions about a possible affinity. As far as I'm aware, fossil fruits from the Nanaimo Group are quite rare, so I would also be interested to know if anything similar to this has been found before or not. (Fossil is ~1.5cm long, the angle it's photographed at isn't completely flat). Front (note the longitudinal groove): Rear (this end is partially eroded away, presumably because it was the part sticking out of the rock): Top (note the round scar of the hilum): Bottom: Surface texture: Thanks for your attention! @Wrangellian@fossisle

Canadian Amber (Allenby Fm., 52.5-48 Ma)
Barrelcactusaddict posted a gallery image in Member Collections
From the album: Fossil Amber and Copal: Worldwide Localities
3.0g of amber, from the same lot in the two associated entries. This mid to late-Ypresian material comes from an old site near the abandoned mining town of Blakeburn, which site and its gangue piles are now technically owned by a coal mining company (although the existing legal claim of the individual who collected this amber is being overruled by the company). The amber is found primarily in association with Metasequoia sp. remains/imprints, however Pinus and Pseudolarix (among others) remains are also found in a lesser quantity at the site.© Kaegen Lau

Rough amber from an old site near Coalmont, British Columbia. The original site is now closed to collecting, since a mining company somehow got a court injunction and has "jumped" the owner's legal, active long-standing claim. The claim owner has informed me that he is not able to collect larger specimens (>3g fraction), as he had been able to in the past.© Kaegen Lau

Hi all. A real Newbie here wondering if anyone can ID this as Coprolite? It's 3" in length and weighs 100 grams (it's hard as rock). I found it amongst all the rocks on the beach on the eastern coast of the island (Georgia Straight side). Does that mean that it may have come from an ancient sea creature? Thanks for any info. Cheers!
