I've been out a number of times already this year, mostly revisiting local spots until the semester is done and I can commit to more exciting locations. Some of my previous trips this month even netted another fragment of Terataspis that will need some patient prep to reveal as anything halfway decent. The snow is gone, and today saw temperatures soar to 20 degrees. A site with about a few acres of dumped mid-Devonian rock just north of me in town seemed a natural fit for the day. I had prospected it before, and generally knew what to expect: a miserable, dense, mostly blank, occasionally reworked limestone with intervals of high energy "beds" (more like chaotic jumbles that split wherever), filled with small horn coral, brachs galore, some gastropods, occasional giant rostroconch, a few tentaculitids, and of course my focus: trilobites. The trilobites will never appear complete in these environments, of course. Although their pygidia occur frequently, other parts do not, and the diversity is fairly low -- mostly proetids. A few representative Pseudodechenella sp.

Well it has finally opened to the public on December 4rth. "The new Dawn of Life Gallery" at The ROM is perhaps the best gallery on the planet covering the earliest life to the emergence of land dwelling creatures. I was fortunate to have a tiny part in the new gallery having prepared a number of the museums specimens and also having donated and sold them some pieces . Here is a tiny taste of what you can see in the new gallery. It will not disappoint.

Hi everyone, I am very new to fossil hunting and am hoping to find some trilobites. I am located in along Lake Huron in Ontario, Canada on a rock formation from the middle Devonian period. I broke open a rock on my second trip and found this but I am not positive what it is. I think it could be a fossilized pygidium from a trilobite but i am really just guessing. I have attached to photos of the fossil, if anybody could help me identify it or steer me in the right direction that would be greatly appreciated. Thanks.

Found this along the shores of Lake Ontario in Canada. Measures about 2" x 1.5". Any ideas what it is/was? Thanks!

I purchased this from a woman in Ontario, Canada with no other information as to what it may be. Does anyone have any ideas?

I was walking my dogs this afternoon (EST) and I noticed a rock that was kind of rusty looking but spherical from the angle I was looking. I picked it up for some reason and when I flipped it over I saw some fossils I've seen before and a couple I haven't. The more I looked at it I thought this maybe part of a skull that sea life made a home in possibly? There is one fossil that almost loos like it still has color but that maybe the hue off the marbleized fossil I guess too. The fossil is very heavy and round almost oval shape aside from one section that is maybe missing? Also looks like a very small piece broke off or was scrapped off. You can see the white spot where this may have happened in the side view pics. I couldn't find my tape measure sorry. I used a AAA battery in a bunch of pics since I'm pretty sure that's a world wide standard. You can also refer to a 500ml Round bottom Pyrex flask. It's not a perfect fit but it would be very close to filling the bottom half of the flask.

My friend found this on a beach on lake erie, I'm thinking barnacles?

This was found in SW Ontario along the coast of Lake Huron. It looks trilobite-like, but I’m new to the area and am unaware of fossils in area. I would appreciate any assistance in identifying this. Thank you!

Trypaulites calpyso Trypaulites erinus Total: 40 New: 17 I'll be parking all my trilobite hunts for the year in this thread. With winter ending much sooner than we are accustomed to up here, it's about time to get back into the hammer-swing of things. This year is an ambitious one, no less on account of having spent some quality time with old literature, maps (new and old), to plot out a series of areas to prospect all across the province. A significant amount of fieldwork is planned as part of a broader research project. This past weekend was the season opener for me, with temperatures hitting about 4 Celsius on Saturday, and near 12 Celsius on the Sunday. By now, almost all the snow has burned off, with just a few shadier spots remaining. This is the view as I set out through the bush around sunrise. The ground was still frozen, which was fine as it made trekking over mud much easier.

Two more that stump me! The first is from Humber River, and the second was found on the beach of Lake Ontario, in Toronto. 1. I see iron deposits, I assume. Judging from the staining and the smell it leaves on my fingers! But the little whorls are confusing. As are the little flat edges that sparkle and that serrated? Indentation. I suppose 'serrated' isn't the word, but I can't quite describe it! Seems like a weird conglomerate of different things. (Fear not. The needle is used for depositing water into my ant colonies but I figured it was a good way to measure as it doubles as a tiny ruler.) 2. I'm fairly certain this is a just a rock, but I'm not sure what's going on with the shining bits. Pyrite perhaps? Though pyrite isn't a fossil, of course. Hopefully this isn't an irritating ask! If it is, I'll happily refrain from any further rock shenanigans.

Hello! I was here a few years ago asking for ID, and I'm back again. I scour the Humber river in Toronto for water insects and rocks, usually, and I found what I think are some fossils! If anyone can help me identify them, I'd be very grateful. I have some pictures below. The 'fossil', if it is a fossil, is just slightly under a centimeter across. (As a bit of an aside, I'm an avid fan of rocks but I can't usually figure out what they are, other than nice to look at. Is this an appropriate place for potentially IDing those, as well? Or should I find a rock forum in particular?) 1. This is the only one I think I know! I'm assuming those are crinoid bits in there. The rock itself is a little over two inches across. This is the front, And this is the back. 2. All I know is this seems shellish. Front and back, below. About an inch, maybe a little more. 3. This one seems similar to the one above, but I've got an eye for bugs, not for fossils. An inch across, if not a little more. 4. No idea where to start with this. The upper left corner is what caught my eye. The macro shot is a bit blurry. My apologies! The 'fossil', if it is one, is about a centimeter wide, slightly less.

While going through mostly Amherstburg/Lucas Fm material with some Dundee Fm today, I encountered this fairly large cephalon (~5 cm wide). Odontocephalus (n.sp?) pygidia have appeared in this material, along with Pseudodechenella and Crassiproetus (and just one tiny "Mystrocephala" pygidium). Overall, though, it is miserable, chalk-cherty, bituminous, generally low sedimentation material. It seems a match for Trypaulites, but it seems a bit on the large side (and the exaggerated anterior "prow" gives me pause). Apart from age of the material, I can likely rule out Anchiopsis given the absence of the occipital spine. If it is Trypaulites (making my first cephalon find of this genus), I am not entirely satisfied with making that call more certain on the basis of either images in Ludvigsen or Lespérance. I could be overthinking what could simply be an artifact of preservation or a natural in-genus morphological variation, but always best to get a second opinion.

A recent visit to one of my special Dundee Fm locations yielded the usual assortment of fragments of Coronura aspectans, Pseudodechenella sp. Odontocephalus (n.sp.?), Trypaulites sp., and Crassiproetus sp. This one fragment was found in the talus of my splits (so I could not locate the impression, and it sits on the natural edge of the rock). The material is a near-shore fissile facies of the Dundee Fm (SW Ontario). Comparing against other usual fragments has not made for a satisfactory enough match for me. I'm including a closeup grey-scaled image of the fragment, and a regular photo (which includes a Coronura aspectans pleural segment above the fragment). The pygidial "margin" appears quite a bit larger and effaced. For scale reference, the pygidial axis measures 1.1 cm in length.

I know crinoid "forests" are a dime a dozen, but still its nice to find one so packed . . . And some bryozoan pieces, my first that I can identify with a bit of confidence . . . but please correct if I'm mistaken. Cheers!
